Ebox T8 V Octa-Core Android TV Box Review – Part 2: Android Firmware, EBMC, and Benchmarks

January 25th, 2017 1 comment

EBox T8 V (version 5) is the new EntertainmentBox.com  TV box specially geared towards the UK market with its choice of apps and online shop based in the United Kingdom. It’s an upgrade to EBox T8-4 I reviewed last year, replacing Amlogic S905 quad core processor by Amlogic S912 octa-core processor, but keeping most of the same features including the SATA bay and EBox user interface. Since we’ve already checked out the hardware, likely based on Zoomtak U Plus, I’ll focus on the firmware in the second part. It will be a shorter reviewed than usual since I have already tested many Amlogic S912 TV boxes, and I’ll refer to T8-4 review when the user interface is identical, and instead focus on what has changed, and the usual suspects like audio pass-through, 4K video playback, DRM support, WiFi performance, etc…

EBox T8 V Setup Wizard, Setup, OTA Firmware Update, and Default Apps

I had already plugged the provided 1TB SATA drive into the device during the unboxing post, but I’ve also connected another USB hard drive, as well as HDMI and Ethernet cables, the RF dongle for S77 Pro air mouse that came with the box, a USB keyboard to take screenshots, and finally the power cord.

The power button on the box should be red, so if you want to start the TV box, press the button on the box, or the power button on the IR remote control, the power button will change to blue color, and the display will show “boot”. If you want to use the air mouse to turn on the device, you’ll need to use the IR learning function to learn the power key from the IR remote control. I’ve tried and it works well. The boot normally takes around 30 to 35 seconds. Note that the boot animation includes some music, which can be annoying if other people sleep, and you forgot to turn the volume down…

The first time, you’ll go through a setup wizard for language, screen scale network, since nothing has changed here, I invite you to check EBox T8-4 Setup Wizard & Configuration section of my previous review for details.

Beginners Launcher – Click for Original Size (1920×1080)

The launcher is also the same, but you now have an option to switch between the “beginners launcher”, which includes Ebox Apps Hub and Ebox app for support, and the more barebone “experienced launcher” shown below.

Experienced Launcher – Click to Enlarge

The Experienced Launcher setting interface is exactly the same as in T8-4, but the company made another Settings app for the Beginners Launcher.

As fas I could tell however, all settings were the same, but just presented in a different way. The Speed Test is new, but it’s just an Ookla speed test to check your ISP performance. Note my fiber optic connection is 20/10 Mbps to the bandwidth was maxed out in that test.
The Advanced icons redirect to the familiar Amlogic Settings app.

It’s also interesting to quickly check out the system info that shows the model number is q201_9377, which can be useful in case you’ll want to use an alternative firmware. Few people will likely try that, since you pay extra for firmware and support for the box.

Click to Enlarge

The list of app is what makes this box further different from the competition with UK specific apps such as BBC iPlayer, FilnOn Live, and WookieSports, with the latter not present in T8-4.

The company did not include TVCatchUp app this test, but for people who wants to watch UK programs but live outside the country, IPvanish app was added to let you setup VPN. You may want to check Installed App & IPTV streaming section in T8-4 review for details about the UK streaming apps.

Finally, I went to EBox OTA, it could find a new firmware, and the upgrade went smoothly.

Check out OTA firmware section of my previous review for more info about that.

Power consumption is fine with 0.2W is power off mode with the two hard drives connected, and around 8 Watts at idle. The air mouse also worked well, and once you’ve programmed the IR remote control’s power button to the air mouse, you won’t need the IR remote at all. If you exclusively run Kodi (EBMC) then the IR remote control might be a little better since you can access some features like Zoom, aspect radio, and audio directly from the remote, and you won’t need a mouse pointer at any times.

The user experience of the new T8 V was very much like the one of the previous model with the firmware working well, except that I had a “App not Responding” window appear twice, and the mouse cursor is quite small when you set video output to 4K.

Video and Audio Support in EBOX MC (Kodi 16.1) & DRM Info

EBOX Media Center (EBMC) is based on SMPC 16.4, itself a fork a Kodi 16.1 with optimization for Amlogic processors.

Before playing any videos, I disabled amcodec as instructed in a paper included with EBOX T8 V package.

I also enabled automatic frame rate switching via “Adjust display refresh rate” option….

… as well as audio pass-through, with Dolby and DTS. Note that DTS-HD and TrueHD options are missing, and as we’ll see below not working, so you’d better enable Dolby Digital (AC3) Transcoding too.

I played 4K videos over a SAMBA share using Gigabit Ethernet:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 (H.264, 30 fps) – OK
  • sintel-2010-4k.mkv (H.264, 24 fps, 4096×1744) –  OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265) – OK
  • MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC) – plays, but not perfectly smoothly
  • phfx_4KHD_VP9TestFootage.webm (VP9) – OK
  • BT.2020.20140602.ts (Rec.2020 compliant video; 36 Mbps; 59.97 Hz) – OK
  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • big_buck_bunny_4k_H264_60fps.mp4 – Not smooth, and audio delay (OK, not supported by Amlogic S912)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) –  OK
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – Slow motion
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – OK, but not perfect at all times.
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Plays but could be smoother

4K video playback working about as well as on other Amlogic S912 TV boxes, but automatic frame rate switching does not work, so if the video output is set to 4K @ 60 Hz, and you play a 24 fps video it might not be as smooth as it could be.

HDMI audio-pass through works but is limited to Dolby and DTS 5.1. Tested with Onkyo TX-NR636 A/V receiver.

  • AC3 / Dolby Digital 5.1 – OK (Dolby D 5.1)
  • E-AC-3 / Dolby Digital+ 5.1 – OK (Dolby D 5.1)
  • Dolby Digital+ 7.1 – PCM 2.0, no audio *
  • TrueHD 5.1 – PCM 2.0, no audio *
  • TrueHD 7.1 – PCM 2.0, no audio *
  • Dolby Atmos 7.1 – PCM 2.0 with audio *
  • DTS HD Master – DTS 5.1 only
  • DTS HD HR – DTS 5.1 only
  • DTS:X (not supported by Onkyo TX-NR636) – DTS 5.1 only

* If you set “Dolby Digital (AC3) Transcoding” in the settings, audio will be transcoded, and output Dolby D 5.1 audio.

EBox T8-4 Benchmarks – Antutu, Storage and Networking

I’ve run Antutu 6.x to make sure the system did not have any issue with performance, and T8 V achieved above 41,000 points, in line with the scores of other Amlogic S912 TV Boxes.

The 1TB internal hard drive (NTFS) shipped with the device was properly recognized with performance ~30 MB/s you’d expect from USB 2.0, while my external hard drive NTFS and exFAT partition could be mounted, and also delivered as expected with the recurring low write speed (5.88 MB/s) on exFAT partitions typical of the vast majority of Android TV boxes. Note that the 44.50 MB/s read speed for the exFAT partition is likely wrong, and affected by the slow write speed.

Click to Enlarge

Internal storage performance (35.01MB/s & 12.15 MB/s) is OK without being outstanding, and works well enough.

My very first experience with WiFi did not quite go accordingly to plans, as the box hung when I enabled WiFi in the settings. My second attempts was successful with a 433 Mbps connection to my 802.11ac router. Performance was however underwhelming with an average of 2.4 MB/s transfer rate, that’s quite typical of Amlogic S905X and S912 TV boxes.

Conclusion

EBox T8 V offers user experience very similar to EBox T8-4, with slightly faster performance, decent 4K video playback which adds VP9 support, better support for audio pass-through albeit limited to Dolby Digital and DTS 5.1, and a few pre-installed video streaming app for the UK. I did not have any issues with the internal hard drive this time, but WiFi performance is not quite as good as on EBox T8-4.

PROS

  • Stable and responsive firmware
  • Easy to setup & e thanks to setup wizard, and bundled Air mouse.
  • 4K video playback in EBMC (based on SPMC) with H.264, H.265 and VP9 well supported
  • HDMI audio pass-through working for DTS and Dolby Digital (AC3) 5.1
  • Pre-installed IPTV apps for the UK market such as BBC iPlayer and Filmon, as well as a VPN app.
  • 2.5″ internal SATA bay
  • OTA firmware update
  • Good customer support with Live chat, forums, and online documentation

CONS

  • HDMI audio pass-through does not work for Dolby TrueHD and DTS HD
  • Automatic frame rate switching is not working
  • WiFi performance could be better
  • DRM support limited to Widewine Level 3
  • No Dolby and DTS licenses
  • Small mouse pointer when 4K is selected
  • Boot animation includes some music (potential issue at night).

EBox T8-4 + S77 Pro air mouse + 1 TB HDD bundle I reviewed can be purchased for 185.87 GBP including VAT (~$234 US), but you can also purchase the box with the standard IR remote control only for 104.99 GBP including VAT (~$132 US), or select other bundles with gamepad and/or wireless keyboard.

Mecool BB2 Pro Review – TV Box with DDR4 Memory – Part 2: Android Firmware, Benchmarks, Kodi

January 12th, 2017 9 comments

Most Android TV box comes with DDR3 or DDR3L memory, but Mecool BB2 Pro comes instead with 3GB DDR4 memory that’s supposed to offer 50% increased memory bandwidth. That’s why I was interested in reviewing the box. I’ve already checked out BB2 Pro hardware in the first part of the review, so the second part will focus on the firmware, video playback in Kodi 17, and benchmarks to find out if there’s any improvement over other Amlogic S912 using DDR3 memory. It’s not the first DDR4 box I’ve tested however, as Eweat R9 Plus powered by Realtek RTD1295 processor also included DDR4 memory, but based on my tests, there’s was no noticeable differences with Zidoo X9S based on the same processor, but with DDR3 memory. But this time, we’ll see if it is any different with Amlogic platforms.

First Boot, Settings and First Impressions

I connect a USB 3.0 hard drive to one of the USB 2.0 port, and a USB hub to the other port with two RF dongle for an air mouse and a gamepad, as well as a USB keyboard. I completed the setup with HDMI and Ethernet cables, and finally the power supply.

The system will boot automatically when you connect the power, no need to press the power button, and the boot will typically take around 25 seconds. Please note the boot animation logo could with some music, so the boot is not silent, which may be annoying if you want to use the box while others are sleeping, and turned on the TV before the box.

The launcher will look similar to regularly readers as it’s exactly the same as the one found in K1 Plus, another TV box also made by Videostrong. The notification bar is enabled by default, but not the status bar which can be enabled in the settings. This option should really be present in all boxes.

mecool-bb2-pro-appsThe list of preinstalled apps include the Play Store, Kodi, Netflix and others. You’ll also notice Kodi Updater, an app to update the likely-custom version of Kodi used in the box.

bb2-pro-kodi-updaterMy version was Kodi 17.0-Beta3 and was the latest available at the time.

The settings are also basically the same as in K1 Plus, and other Amlogic S905/S905X/S912 TV boxes. I had no troubles using WiFi and Ethernet, and set my resolution to 4k2k-60Hz supported by LG 42UB820T Ultra HD TV. Some less common settings include RGB mode (maybe to fix some pink screen issues), and Status bar (on/off), and there are settings for HDR and HDMI self-adaptation (auto framerate switching).

The internal storage has a single unified partition with 762MB used. The total capacity is reported to be 16.00GB but that’s obviously a hard-coded value, possibly to avoid customers complaining there’s not 16GB storage in their 16GB TV box box.

The box could also mount NTFS and exFAT file systems in the USB hard drive. A FAT32 micro SD was also supported.

The “About MediaBox” section report the model number is BB2 Pro running Android 6.0.1 on top of Linux 3.14.29. The firmware is rooted. OTA firmware update appears to have been implement through “Update” app, but it would detect no new firmware, so I could not test it.
bb2-pro-about-mediabox Google Play Store worked just fine, except for Bluetooth LE apps such as Mi Fit or Vidonn Smartband. Albeit it should be easy to fix, this is an issue common to almost all Amlogic S912 TV boxes. I also install the free version of Riptide GP2 through Amazon Underground.

I had no troubles using the infrared remote control up to 10 meters, and the IR learning function worked too. However, I used MINIX NEO A2 Lite air mouse for most of the review since it’s more convenient in Android. I’d recommend an air mouse with keyboard and IR learning function (to be able to turn on the device) for the best user experience.

A short press on the power button of the remote control will trigger standby mode, while a long press will pop-up a window to confirm you confirm to power off the define. I could also restart the box from the power button from the remote and the unit.

Power consumption measured in 6 different configurations:

  • Power off – 1.0 watt
  • Standby – 1.3 watt
  • Idle – 3.0 watts
  • Power off + USB HDD – 1.0 watt
  • Standby + USB HDD – 1.4 watt
  • Idle + USB HDD – 4.2 watts

Idle power consumption is the same as M12N TV box, but power off power consumption is a bit on the high side possibly partially because of the red LED that is quite bright.

This time I only measured the temperature on the top of the case, as the bottom is bright and my IR thermometer reported wrong values for the bottom. The top of the case temperature was 39°C max after Antutu 6.x, and 44°C max after playing Riptide GP2 for about 15 minutes. I also checked the soc-thermal value in CPU-Z after the games and it was 78°C, against around 55 °C in idle mode. Riptide GP2 played fine, but not perfectly smooth, like on other Amlogic S912 TV box, and performance was constant. I did not notice any obvious improvement over S912 TV boxes using DDR3 memory.

Mecool BB2 Pro feels like using other Amlogic S912 TV boxes with a stable firmware, and good performance overall, but again I could not really noticed any performance boost from DDR4 memory.

Video and Audio Playback with Kodi, Antutu Video Tester, and DRM info

BB2 Pro runs Kodi 17 Beta 3, or at least a custom version of it with TVaddons.org add-ons installed. I played most videos samples from a SAMBA share through Gigabit Ethernet.

4K video playback was OK, but for whatever reason I could not play any VP9 videos:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 – OK
  • sintel-2010-4k.mkv – OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK

  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • big_buck_bunny_4k_H264_60fps.mp4 – Not smooth, and audio delay (as expected since the VPU does not support 4K H.264 over 30 fps)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) –  OK
  • 暗流涌动-4K.mp4 (10-bit H.264; 120 Mbps) – HDD: Slow motion, and many artifacts (Not supported by S912 VPU, software decode)
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 30 fps; 243 Mbps; no audio) – HDD: Not smooth
  • tara-no9-vp9.webm (4K VP9 YouTube video) – Won’t play, stays in UI.
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) –Won’t play, stays in UI.

I also tried the 3 VP9 videos above with MoviePlayer with all I got was a black screen. That’s too bad, as I wanted to see if DDR4 memoryu would improve “Curvature of Earth” playback that is not 100% smooth on all other devices I’ve tested. Automatic frame rate switching is not working in Kodi, and MoviePlayer, so you won’t get perfect playback for 24 fps videos, unless you set the frame rate manually.

Audio support is not quite perfect, just like in other Amlogic S912 TV boxes I’ve tested. PCM output (stereo downsampling) works with Kodi, but not MX Player/MoviePlayer apps, and HDMI pass-through using Onkyo TX-NR636 receiver is a disaster in Kodi, and somewhat works with MoviePlayer.

Network (WiFi + Ethernet) Performance

In order to test WiFi performance, I copied a 278MB file between a SAMBA share and the internal storage – and vice versa – using ES File Explorer, both using 802.11n @ 2.4 GHz, and 802.11ac (433 Mbps). The results are not that good, although download speed is quite faster than upload speed.

WiFi Throughput in MB/s - Click to Enlarge

WiFi Throughput in MB/s – Click to Enlarge!

Sadly those poor WiFi numbers are quite typical of Amlogic S912 TV boxes. Note that download speed for 802.11ac was 5.05 MB/s on average, so not so bad, but upload speed @ ~1.5 Mb/s brought the average down significantly.

For some strange reasons Gigabit Ethernet suffered from the same issue, as transferring a 885MB file took 50 seconds to download (17.7 MB/s), but  2 minutes 18 seconds to upload back to my local server (6.41 MB/s). I’ve never seen that problem on other devices. My SAMBA server is connected via Gigabit Ethernet and uses a SATA drive (not USB) capable of 100 MB/s writes.

Trying a full-duplex transfer with iperf confirmed the issue:

Asymmetric performance happens more often with iperf since transfers occur in both direction at the same time. Nevertheless there seems to be some minor issues with Ethernet.

Storage performance

We’ve already seen the system could handle NTFS, exFAT and FAT32 file systems for external storage, so I tested the performance of both NTFS and exFAT partition on my hard drive as well as the internal memory using A1 SD bench app.

Click to Enlarge

Click to Enlarge

Note that both internal memory and exFAT partition had “cache reads”, which means reading operation was at least partially done from RAM. We can discard read results for both, especially since 65.71 MB/s is totally impossible over USB 2.0. What we can see however if that exFAT write speed is quite poor, but again that’s common to almost all TV boxes I’ve review. USB 2.0 NTFS partition read performance is about the best you can get through USB 2.0, and write performance is OK. The eMMC flash write speed is quite good @ 48.57 MB/s, so read speed is likely to be good too, but lower than the 104.58 MB/s reported by the app due the “cached read”.

Gaming

As I looked for benefit from DDR4 memory in this review, I was hoping that maybe games would benefit one way or other. Riptide GP2 with maximum graphics settings seemed to perform just like other Amlogic S912 TV boxes, that is… playable, but not extra smooth like on Xiaomi Mi Box 3 Enhanced for example. Performance was constant over the 15 minutes I played the game, so I did not notice any overheating and throttling issues.

Mecool BB2 Pro Benchmarks

So far I have to say I could not notice any user experience benefit from using DDR4 memory, but maybe benchmarks could give a different picture. Let’s check CPU-Z first.

Click to Enlarge

Click to Enlarge

The device is BB2 PRO (q20x) with 8x Cortex A53 cores @ up to 1.51 GHz and a Mali-T820 GPU as expected. Other settings are as expected, and we can see the real internal storage capacity available to the user: 11.87 GB. That’s perfectly normal once we take into account the space taken with the bootloader and Android operating system.

Then I ran Antutu 6.x and compared the results to M12N TV box benchmark results.

Click to Enlarge

Click to Enlarge

BB2 Pro got 363 points extra, but we can consider both devices had about the same performance. RAM test should be interesting and BB2 Pro was about 12% faster. So maybe there’s some benefit, but very minor based on those Antutu results.
mecool-bb2-pro-vellamo
Vellam score is about the same story with BB2 Pro getting 1,488, 1,020 and 2,811 points for respectively multicore, metal, and browser tests, against 1,103 (test failed to complete), 1,052 and 2,758 points on M12N. If we discard the multicore that failed to complete on M12N, results are basically the same.

Click to Enlarge

Click to Enlarge

The last benchmark of this review, 3DMark Ice Storm Extreme, shows a little improvement as BB2 Pro got 6,000 points against 5,732 points for M12N. But it’s hard to tell if it is because of the DDR4 RAM, or some improvements of the GPU drivers. If we look into details of the score, most of the improvement is with the Physics score & test (9263 point / 29.4 fps vs 8163 / 25.9 fps).

Conclusion

I have not been able to find a single use case showing a clear benefit from using DDR4 memory instead of DDR3 memory. Apart from that Mecool BB2 Pro works reasonably well, it feels fast enough and the firmware is stable. However, it also comes with most of the same caveats found in other Amlogic S912 TV box, including mediocre WiFi performance, lack of HDMI audio pass-through support in Kodi (except Dolby Digital 5.1) and DTS HD 7.1 not working in the local player (MoviePlayer), automatic framerate switching not working at all, and for some reasons I could not play any VP9 in the device.

PROS

  • Responsive and stable Android 6.0 firmware
  • Acceptable 4K H.265 and H.264 video playback in Kodi 17and MoviePlayer apps
  • HDMI audio pass-through for Dolby 5.1, DTS 5.1, and TrueHD 5.1 and 7.1 in MoviePlayer
  • Good internal storage performance leading to fast boot time (<25 seconds), and overall good system performance
  • exFAT, NTFS, and FAT32 file system support for external storage
  • IR remote control working up to at least 10 meters and IR learning function
  • OTA firmware update support (could not confirm whether it is working since no new firmware has been released yet)
  • Option to disable/enable status bar in settings

CONS (and bugs)

  • HDMI audio pass-through and automatic frame rate switching not working properly in Kodi, except for Dolby Digital 5.1
  • HDMI DTS-HD MA/HR 7.1 not supported in MoviePlayer (uses DTS 5.1 instead)
  • BB2 Pro firmware won’t play VP9 videos; tested with Kodi and MoviePlayer apps
  • Mediocre WiFi performance, especially for uploads. Ethernet is also somewhat slow for uploads (no problems for downloads).
  • DRM: Only supports Widevine Level 3
  • Dolby & DTS licenses not included (Only a problem for apps other than Kodi, for people not using HDMI or S/PDIF audio pass-through)
  • Power off power consumption on the high side (1 watt)
  • Boot logo includes some music (not too high volume, but it can be an issue if you start the box at night, and forgot to mute or lower the volume)
  • Google Play can’t install apps with Bluetooth LE requirement

I’d like to thank VideoStrong for providing a sample for review. Distributors and resellers may contact the company via the product page to purchase in quantities. Mecool BB2 Pro can also be purchased for $66.66 and up on Banggood, GearBest, and eBay, or  about the same as YokaTV KB2 with 3GB DDR3 instead of 3GB DDR4, but 32GB storage instead of just 16 GB, with the rest of the specifications being equal.

Eweat R9 Plus TV Box Review Part 2 – Android, OpenWrt, and HDMI Recording

December 24th, 2016 24 comments

Eweat R9 Plus is a device powered by Realtek RTD1295 SoC combining main functions: Android 6.0 TV box, OpenWrt NAS/router, and HDMI recorder thanks to its HDMI input port. It competes directly with Zidoo X9S which has the same features, except while Zidoo X9S has no internal SATA bay and your 2.5″ hard drive just hang outside the box, Eweat R9 Plus comes with an internal 3.5″ SATA bay that makes it much neater on your furniture… We’ve already seen that in the first part for review “Eweat R9 Plus unboxing and teardown“, and I was impressed by the hardware, but the software is even more important, and that’s what I’m going to check out in the second and final part of this review.

First Boot, First Impressions and Setup.

I’ve first inserted a 1TB 3.5″ SATA drive in the device, and then I connected an extra USB 3.0 hard drive, HDMI and Ethernet cables, two USB dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, and a USB keyboard to take screenshots, as well as U4 Quad Hybrid Android TV box to the HDMI input.

Connect the power, press the mechanical power switch on the back, and the device will boot, typically in about 40 seconds, to the main launcher. There’s no setup wizard like in Zidoo X9S, so you’d have to change configuration separately.

The top left corner includes status icons for USB, Ethernet, Bluetooth, and WiFi, and the top right corner shows the current date and time. The first time the time and date were not correctly update, and I did not get any IP address from my router… That’s because I connected the Ethernet cable to the WAN port, but once I connected it to the LAN port, everything worked fine. It’s just WAN and LAN markings are not quite correct…. Let’s go back to the launcher with 7 large icons, the “R9 Plus” icon is linked to Chrome browser (so we have two Chrome links), apps to the list of apps, EWMC links to Kodi 16.1, and 4K to the local file browser/media player. We also have 3 shortcuts on the botton that can be customized to your needs. Sadly, there’s no status nor notifications bars which can be a pain in some use cases. The small blue “rocket” on the of EWMC icon, is actually the mouse cursor (red in reality, but the screenshot app turns that blue).

The system comes with a bunch of apps including Netflix, HDMIRecorder, and QuickSupport, and I could install my own without any issues using Google Play and Amazon Underground.

eweat-r9-plus-displayThe front panel display on the unit is a little more useful than most, as it will show the current time of the day when not playing videos or music, and instead display the current video time with 4K video player, but not Kodi, while playing media files.

If you are interested to find out more about the settings, I invite you to check the Settings section of Zidoo X9S review, as Eweat R9 Plus has basically the same settings, except only “Auto 1080p24” option is available in the Display section, Deep Color Mode (AUTO, 12-bit, 10-bit, OFF) is gone, and the Playback section is missing together with “Auto 29.97/59.94 Hz”, “Force SD audio”, “Enable low performance mode (less buffer for playback)”.

I could set the resolution (“TV System”) to 3840x2160P @ 60Hz without any issues, but I’ve noticed the video output will sometimes fall back to 720p or 1080p after a power cycle. I could not find any option to adjust overscan either, so I had some black zone on all edges of my TV. Those are issues, but the latter at least should be easy to fix via firmware upgrades.

Once I found that LAN is actually WAN, and WAN is LAN, I had no troubles at all with Ethernet and WiFi, and OpenWrt options are also exactly the same as on Zidoo X9S.

You only get 9.31GB of the 16GB in Android because some part is reserved to OpenWrt, but it still more than the 8.91GB I had on X9S. In theory it should be plenty enough, but after a day or two of use, my internal storage was completely full, despite not installing that many apps.

android-storage-fullEventually I found that since my 1TV hard drive had millions of files, Android’s “Media Storage” activity had created two very large databases. Disabling Media Storage fixed the issue, and after clearing the data from “Media Storage” I had close to 8GB free. Alternatively you can add an empty .nomedia files in the directory you do not want to system to scan, for example the root of the harddrive if you don’t want it to scan anything.

Going into the About device section, we can see “R9Plus” model runs Android 6.0.1 on top of Linux 4.1.17.

about-device-r9plusThe firmware is rooted, and OTA firmware update is done with SystemUpdate app, and I could upgrade from R9PLUS_V1.1_20161130 version to R9PLUS_V1.02_20161217 version which I used in most of the review. I had to disconnect the USB drive, or the update will fail. You can leave the SATA drive inside the box during firmware upgrades.

eweat-r9-plus-firmware-updateThe update went well, and did not mess with my settings, apps, and media files.

The included IR remote worked fine up to 10 meters, but I’d really wish higher end devices such as R9 Plus would ship with an air mouse by default. I had to jungle between the IR remote control and MINIX NEO A2 Lite air mouse quite often depending on the app I used. Realtek apps such as HDMIRecorder, 4K media player, and File Manger may work better with the infrared remote control.

Eweat R9 Plus firmware is stable and responsive, but there are a few small bugs here and there that should be fixed, like the lack of screen scale option, video output resolution set by the user is not always used after a reboot, there’s no status nor notification bars, etc… I’d also wish such higher-end systems would come with an air mouse with keyboard by default to be able to fully control the TV box with a single remote.

Power Consumption and Temperature

Power control support is basic with only on or off, no standby or reboot, but the power consumption numbers are OK, albeit a little higher than Zidoo X9S, maybe because of the 3.5″ SATA drive instead of 2.5″ SATA drive:

  • Power off (SATA HDD) – 0.3 Watt
  • Idle (SATA HDD) – 9.2 Watts
  • Power off + SATA & USB HDD – 0.3 Watt
  • Idle + SATA & USB HDD –  11.2 to 12 Watts
  • SATA HDD (Copy file to SAMBA share) + Play 4K video from USB HDD + miniDLNA in the background – 18 to 19 Watts

If you has a drive with many files, miniDLNA – enabled in OpenWrt settings as DMS (Digital Media Server) – will take a lot of CPU and I/O resources, so if you don’t need it, make sure to disable it. Idle power consumption numbers are with DMS disabled.

While there’s no standby mode, we’ve seen with Zidoo X9S that standby mode is not that useful as networking and drives are all turned off. It’s just must faster to boot than from power off mode. Most cheap Android TV boxes cannot handle more than one USB hard drive, but Eweat R9 Plus had no troubles with a SATA hard drive and a USB 3.0 drive. It might be possible to add yet another USB 3.0 drive, as the power supply has a 30 Watts capacity.

It’s no surprise that with a large metal case, the device stays relatively cool at all times. The maximum temperatures measured with an IR thermometer on the top and bottom of the device were 35 and 37 °C respectively after Antutu benchmark, and 40 and 50 °C after playing Riptide GP2 for 15 minutes.

Video & Audio Playback with Kodi 16.1 and 4K App, Antutu Video Tester, and DRM Support

R9 Plus comes with Kodi 16.1 (EWMC) and 4K app to browse and play media files with the internal player. So I’ve started by testing 4K videos with both. Bear in mind that while Realtek RTD1295 supports 10-bit HEVC/H.265 up to 60 fps @ 4K, H.264 is limited to 24 Hz, which will be a problem with you shot 4K H.264 30 fps videos with a camera or your smartphone, and 4K VP9 @ 60 fps is supposed to be supported, and with DDR4 memory I had hope some progress may be made here, but unfortunately the limit is really 30 fps, which could be an issue with some (downloaded) YouTube videos. Out of Specs videos are prefixed with OoO.

For some reasons Kodi 16.1 will fail to start playing some videos the first time, but play them the second time. Just like on Zidoo X9S – but worse – Kodi 16.1 implementation is not as good as the internal player, so for best user experience you’d have to use the 4K player. Automatic refresh rate switching works with 4K app, with 23.975/24Hz, 25 Hz, 29.97 Hz and 59.94 Hz with the latest firmware. It does not work at all with Kodi.

For so the audio tests, I’ve stopped using Kodi, and only used 4K app with PCM 2.0 downmixing and audio pass-through via HDMI.

Audio Codec in Video PCM 2.0 Output HDMI Pass-through
AC3 / Dolby Digital 5.1 OK Audio OK (DD 5.1), but wrong aspect ratio
E-AC-3 / Dolby Digital+ 5.1 OK OK (DD 5.1)
Dolby Digital+ 7.1 OK OK (Dolby D+ 7.1)
TrueHD 5.1 OK OK (TrueHD 5.1)
TrueHD 7.1 OK OK (TrueHD 7.1)
Dolby Atmos 7.1 OK TrueHD 7.1
DTS HD Master OK OK (DTS-HD MSTR)
DTS HD High Resolution OK OK (DTS-HD HR)
DTS:X (not supported by Onkyo TX-NR636) OK DTS-HD MSTR

So HDMI audio pass-through is working very well, and I did not experience some of the audio cuts I had on Zidoo X9S with Onkyo TX-NR636 receiver. Those may have been fixed since Zidoo X9S review however.

Below are a few screenshots from 4K video app starting with the list of storage devices/partitions…

I’ve also quickly tested Blu-ray ISOs (Sintel and Amat videos) and both could play. Finally, I play a 2-hour 1080p video to make sure the system can play a full movie, which I does.

Antutu Video Tester score (820 points) is a little lower than on Zidoo X9S (888).

eweat-r9-plus-antutu-video-testerBut the videos that failed are exactly the same:

zidoo-x9s-antutu-video-tester-resultsDRM info crashed each time, just like on X9S, so there’s problably no DRM support at all.

HDMIRecorder App

Eweat R9 Plus HDMIRecorder, as its name implies, allows you to record video from an HDMI input source. It can record up to 1080p @ 30 fps using H.264 codec in TS or MP4 container format, with a bitrate up to 10Mbit/s.

It will also record audio, and you can select the output with the “Path” field. It will create a new “hdmi” directory to store the recorded videos.

Once recording has started, it will work in the background (see recording info in the top right corner below) and you can browse the web, watch other videos, and so on during recording.

I could then connect to the device via SAMBA, and play with the recorded video with both Totem player ad VLC in my Ubuntu 16.04 computer.

Click to Enlarge

That part works fine, and looks similar to Zidoo HDMI In app, however it lacks some goodies like PiP support and UDP broadcasting found in Zidoo X9S. So if so those functions are important to you, Zidoo X9S clearly has an edge of Eweat device here.

OpenWrt and NAS functions

If you want to learn more about settings up OpenWrt on Eweat R9 Plus, I’ll redirect you to OpenWrt and NAS functions section of Zidoo X9S review as all features are identical.

You can control OpenWrt manin function in Android settings…

… and fine tune OpenWrt settings through LuCi web interface.

I tested SAMBA, FTP, and Bittorrent. Performance on Eweat R9 Plus was very good with FTP transfer at ~105 MB/s, and 40 MB/s for SAMBA file copy to the internal SATA, very similar to Zidoo X9S with respectively about 90 MB/s and 50 MB/s.

Eweat R9 Plus FTP Transfer – Click to Enlarge

eweat-r9-plus-samba-transfer

Eweat R9 Plus SAMBA Transfer

Contrary to my experience with Zidoo X9S, BitTorrent worked just fine and the transfer quickly saturated my 20 Mbps Internet connection.

eweat-r9-plus-bittorrentBear in mind that firmware evolves overtime and it’s quite possible Zidoo has already fixed the issue.

This time I also tested OpenWrt opkg system manager to see if it would work. After connecting to the device through ssh, I tried to update the packages and it failed miserably:

So if you want to install packages, you’d probably have to build them yourself, or copy and install opkg packages built for ARM architecture manually.

WiFi Performance

We’ve already seen Gigabit Ethernet works perfectly above with transfers at 105 MB/s through FTP basically saturing the Gigabit Ethernet bandwidth, so I’ll only focus on WiFi in the network performance section. Eweat R9 Plus has excellent WiFi performance with both 802.11n @ 2.4 GHz, and 802.11ac (433 Mbps), roughly matching Zidoo X9S equally good performance.

All you need to know is that Eweat R9 Plus is one of the top devices for WiFi  for all devices I’ve tested over the year.

Miscellaneous Tests

Bluetooth

I could pair Vernee Apollo Lite Android smartphone with “Realtek Bluetooth”, however once I started transferring files from my phone to the device, I either got the message “Unfortunately Bluetooth has stopped”, and when lucky, the transfer was initiated with Eweat R9 Plus showing an overlay message reading “”Incoming file from another device, please confirm…”. That’s all good but since there’s no notification bar, and no pop-up window, I had no idea where to confirm the transfer, and it eventually time out. I could not test Bluetooth Low Energy, because all my device are either broken or lost.

Bluetooth is not completely useless however, as I could get Sixaxis to work with my PS3 BT gamepad clone, and I paired X1T Bluetooth earbuds successfully, and listen to a YouTube video.

Storage

Eweat R9 Plus could mount NTFS, EXT-4, and NTFS partitions on a 1 TB USB 3.0 Seagate expansion harddrive with only BTRFS failing to be recognized. A FAT32 micro SD could also be mounted in read/write mode, as well as my SATA drive formatted with NTFS.

File System Read Write
NTFS OK OK
EXT-4 OK OK
exFAT OK OK
BTRFS Not mounted Not mounted
FAT32 OK OK

A1SD bench app shows excellent sequential read and write for the SATA interface, a decent performance for all supported file systems through USB 3.0:

Click to Enlarge

Click to Enlarge

  • USB 3.0 + NTFS – Read: 37.93 MB/s – Write: 39.28 MB/s
  • USB 3.0 + EXT-4 – Read: 37.67 MB/s – Write: 39.43 MB/s
  • USB 3.0 + exFAT – Read: 37.04 MB/s – Write: 39.28 MB/s
  • SATA + NTFS – Read: 140.78 MB/s – Write: 86.30 MB/s

Eweat R9 Plus looks faster than Zidoo X9S using SATA + NTFS, but bear in mind that the hard drive used was different, so it may explain the difference. However, Zidoo was quite better for USB 3.0 using EXT-4 and NTFS, but quite poor for exFAT, which R9 Plus appears to support well.

Read and Write Speed in MB/s - Click to Enlarge

Read and Write Speed in MB/s – Click to Enlarge

I also measured internal storage performance, but unfortunately A1SD bench reported “Cached Read”, so the read speed is not valid. The write speed of about 55 MB/s is valid, and this is quite good. The actual read speed in the chart below should be lower than 140+ MB/s, but usually read speed is faster than write speed, so performance should still be good.

Gaming

I played Candy Crush Saga with the air mouse, and Beach Buggy Racing (with max quality) using a gamepad, and both games played perfectly well. Then I switched to Riptide GP2, again with maximum resolution settings. It’s started begin playable – but not quite 60fps – just like on Amlogic S905/S912 TV boxes, and Zidoo X9S, but then I noticed the image would freeze from time to time, and after a race was completed,  it may have a 10 seconds black screen before going to the main menu. So I checked the CPU usage in OpenWrt (SSH terminal), and notice miniDLNA with a high CPU usage. So I disabled DMS in Android’s OpenWrt settings, miniDLNA stopped running, and I could play the game for 15 minutes more without issues, nor performance degradation over time.

Eweat R9 Plus Benchmarks

Let’s start with CPU-Z.. R9PLUS (rtk_kylin32) model with a quad core Cortex A53 processor @ 1.4 GHz and a Mali-T820 GPU, so no surprise here.

Click to Enlarge

Click to Enlarge

The device reached 36,076 points in Antutu 6.2 against 34,976 points for Zidoo X9S Antutu score.
eweat-r10-plus-antutu

There are a few potential explanations for the small difference: 1. R9 Plus firmware is more recent, 2. it’s winter here (~ 22 °C), and 3. R9 Plus has DDR4 ram instead of DDR3 RAM. However the strange thing is that R9 Plus RAM score is 3,046 points, but Zidoo X9S got 3,960 points which does not make any sense.

eweat-r9-plus-vellamo
Vellamo 3.x scores are pretty similar with R9 Plus getting 1,430, 881 and 2,539 points for respectively multicore, metal, and Chrome Browser benchmarks, against 1,457, 831 and 2,638 points for Zidoo X9S. So it looks like DDR4 memory does not help for any benchmarks, including 3Dmark’s Ice Storm Extreme.

Click to Enlarge

4,359 points for Eweat R9 Plus against 4,574 for X9S.

Conclusion

Eweat R9 Plus is a solid device, and I really like the internal 3.5″ SATA bay, internal and external storage, as well as networking performance is really outstanding too. However I would have wished the firmware to have fewer bugs, and just like for Zidoo X9S, Realtek RTD1295 SoC has some limited 4K capabilities when it comes with H.264 and VP9. Getting the optimal performance may require some tweaks like disabling some server services.

PROS

  • Responsive and stable Android 6.0 firmware
  • 4K app plays 4K H.265 videos very well with automatic frame rate switching, and HDMI audio pass-through for Dolby TrueHD and DTS HD audio
  • Excellent Ethernet and WiFi performance
  • Excellent internal and SATA storage performance, and good USB 3.0 performance
  • NTFS, EXT-4, exFAT, and FAT32 file systems are well supported
  • HDMI Input (up to 4K60 input) with video recording up to 1080p30 (4K input is also supported but record at 1080p30 max)
  • OpenWrt NAS functions such as SAMBA, FTP, and BitTorrent running at the same time as Android, as well as router functions thanks to its two Gigabit Ethernet ports
  • Proper power handling with power off, standby, and reboot, and low power consumption in off/standby modes. The provided 36W power supply also allows the connection of multiple hard drives.
  • Dolby & DTS audio licenses are included, so audio will work in any apps
  • OTA Firmware update
  • Good hardware design with internal 3.5″ SATA bay

CONS (and bugs):

  • Realtek RTD1295 VPU limitations:
    • 4K H.264 up to 24 fps which will be an issue for 4K videos recorded with some actions cameras (GoPro/Xiaomi Yi) and smartphones
    • 4K VP9 up to 30 fps, as 60 fps is not well supported. This will be an issue for some 4K videos downloaded from YouTube
  • Kodi 16.1 (EWMC) is not really working that well with many 4K videos not playing smoothly (even those within specs) and automatic frame rate not working. So 4K app is recommended
  • No DRM support (DRM info app will crash)
  • HDMI input works, but does not include features like picture-in-picture and UDP broadcasting found in Zidoo X9S
  • You’ll probably have to use both the include IR remote control AND a air mouse or other input device to fully use the device. A air mouse specifically designed for the box would be a plus.
  • Scale screen option missing in firmware, so I had black edges on my TV the whole time (should be easy to fix with firmware update)
  • No option for status and notifications bars
  • Bluetooth file transfer is unreliable (crash) and there’s no way to confirm file transfer (related to notification bar above)
  • Tweaks may be needed (e.g. disable Media Storage and DMS) for optimal performance if you have a hard drive with many files.
  • The system will not always remember the video output set by the user (e.g. 4K 60 Hz set, but falls back to 1080p or 720p).

Eweat also lacks a community forum like Zidoo, but as long as they keep firmware updates rolling, it may or may not matter to you. Overall, Eweat R9 Plus is also a good device combining 4K TV box, OpenWrt NAS, and HDMI recording functions. Whether that’s right for you depends on your requirements and budget.

The manufacturer sent me the review sample directly. Distributors can inquire the company to purchase in quantities, but if you just need one or a few you can purchase it on Aliexpress for $175.99 plus shipping (about $200) on Aliexpress.

Merry Christmas to all!

YokaTV KB2 Review – Amlogic S912 TV Box with 32 GB Flash

December 15th, 2016 14 comments

CNXSoft: This is another review by Karl about Amlogic S912 based YokaTV KB2 TV box.

Introduction

Today we will be looking at Videostrong YokaTV KB2. Below are the specs from Videostrong website.

yokatv-kb2-specifications

This is my first S912 device so I had high expectation. I have been using it for quite some time now with no major issues. I received approximately 6 OTA updates since I started testing and some welcome updates have come.

Build

When I receive a box first thing I do is take it apart and check out the inside. I was excited when I found out it had 32 gig of storage. It is not too common.

Click to Enlarge

Then when I opened the box I was really happy to see an antenna that wasn’t soldered on. Makes it easy to add a different one. +1 for KB2. Then I noticed the heat sink. It seemed a little small. I was right, it runs warm.

Click to Enalrge

Click to Enlarge

Simple Mod

First thing to do: get this baby running cooler. When stressing the box, the temperature got over 80+°C a couple times. It ran between 70 and 75 °C on average before the mod. The case is mostly plastic except the bottom cover. Bingo! A couple squares of 5mm thermal pads between the board and the bottom of the case and thermal issues are gone.

yokatv-kb2-thermal-hack

I started SetCPU and ran the built-in stress test, it tops out around 72 °C, and quickly cools after stopping the test. I put a square approximately where the CPU is and while I had it open, where the memory is although I don’t think it is necessary. After the mod, the box runs about 60 deg Celsius.

Antutu

For this test I use SetCPU to set the Min and Max frequency for the CPU to 1.5 GHz which is the max for this processor. It will give the best score.

yokatv-kb2-antutu

Network Test

I am not sure why my WiFi was slow on the tests below. I don’t have an AC access point yet. The best I have is N, maybe that is the cause. Some friends over on Freaktab are getting some really good speeds on AC with this box. I might have damaged something when I opened the box.

Below are the results but take them with a grain of salt. I do a simple file transfer test of a large movie with optimum conditions for WiFi then one in more real world scenario.

Apps

I’ve used several apps and only Netflix and Direct Now had some issues:

  • Sling TV
  • Netflix (SD) – Stopped working after updating the app
  • Kodi
  • Chrome – Chrome works really well. I open a bunch of heavy URL’s and it performs excellent. Nothing scientific here. Go to several sites that I visit daily and I felt no lag.
  • Plex
  • Emby
  • HDHomeRun
  • Crackle
  • DirectTV Now – Worked with some hacking
  • Player-MediaCenter App – I will admit it has been a while since I tested out this app. It acts as a DLNA receiver and Airplay receiver. I didn’t have much luck in the past but I tested on my one Apple device the screen mirroring worked.

At some point Netflix stopped working. Keep getting few seconds of video then error 0013 “Sorry, we could not reach the Netflix service….” Not sure if it is Netflix update or box update that caused the issue. I went back and did some more testing to narrow the issue down. If I reverted back to the Netflix that came pre-installed I had no issue.

DirectTV Now is a new service in the US. With some persistence I was able to get it running. Video wasn’t perfect but neither was it on any devices I tested. It was surprising that it plays better on KB2 then Nvidia Shield. It is mostly watchable but stutters some. It is new so hopefully ATT will get this fixed soon. I had to do a couple things to get it working. After Googleing and a lot of experimenting I used 2 apps from play store: Hide My Root and Fake GPS. I also had to make 2 build.prop changes: ro.build.type=userdebug to ro.build.type=user and ro.build.tags=test-keys to ro.build.tags=release-keys. I tried on a couple different boxes after figuring this out and seems to work universally.

Remote Control

The remote is big but there is a built in app that is pretty convenient. There are 4 color coded buttons on the remote that you can customize to launch the apps that you want through an app on the box. There is also a dedicated app button that brings up a listing of all the apps. Everything else is pretty standard. You can also program the remote to turn your TV on and off through a learning feature. But alas I still prefer either an air mouse or touchpad with full keyboard.

Thank the gods…there is an option to turn the navigation buttons at the bottom of the screen off and on in Android settings…It is about a 50/50 split for people that like them and those that don’t. This was the first box that I have tested that gives the user an option.

Audio Passthrough

All the below tests worked. I set Android to SPDIF. I tested with latest SPMC 16.4.2 and Kodi 16.1. Turned on pass-through DTS and AC3 and all the videos below worked with no clipping. I have a 5.1 system. If I didn’t have the AC3 ticked I would get no audio on some. First box with 100% working that I have tested on stock firmware.

4k testing went well. I was able to play all videos smoothly with one player or another that it was supposed to play. Below are the test results. This box does not play 4k H.264 video @ 60fps per sec, so stutter is expected. Kodi and derivatives play best with amcodec turned off. The box ships with Kodi 17 beta but since it is beta, it is not very stable. I uninstalled it, and tested with Kodi 16.1 from the Play Store instead. I am not sure why 4k 8bit H.265 works better with amcodec turned on. I found the same results on S905x boxes. For the testing, I wanted to find the best overall solution and that is Kodi with amcodec turned off.

Alternate Firmware

Super Celeron has put together a nice modification of the latest stock firmware from 11/23. He cleaned up the firmware and made some adjustments to boot to bring idle down to about 1% and got auto frame rate switch working. See full changelog.

So to get 100% working pass-through and auto frame rate switching after installing the firmware above, as well as SPMC version 16.5.2. Codec acceleration is a little muddy at times. 4K files work best with amcodec off, and anything less work best with amcodec on. Below are my settings.

I had this box for a while now and used it as my main box and it has performed really well. Consistent updates from Videostrong is much needed in the box world. I hope it continues. Gigabit Ethernet performed really well. Pass-through working 100% is fantastic and will make a lot of people happy. Video support in Kodi is really good. VP9 support is not 100% but MX player gives everyone an option if they have movies in that format.

I would like to thank Videostrong for sending a review sample. YokaTV KB2 can be purchased on Gearbest, Geekbuying, and Aliexpress for about $68.

Firefly-RK3399 Development Board Will Fly with Rockchip RK3399 Hexa-core Processor

November 25th, 2016 11 comments

ARM Cortex A72 class development boards are usually quite expensive, and cheaper boards like Mediatek X20 development board ($200) appears to be out of stock very often, and software support is limited to Android 6.0. But things look to improve soon, as T-Chip is about to release Firefly-RK3399 development board powered by Rockchip RK3399 hexa-core Cortex A72/A53 processor.

Firefly-RK3399 (preliminary) specifications:

  • SoC – Rockchip RK3399 hexa-core bit.LITTLE processor with dual core Cortex A72 up to 2.0 GHz and quad core Cortex A53 processor with ARM Mali-T860MP4 GPU with OpenGL 1.1 to 3.0 support, OpenVG 1.1, OpenCL and DX 11.
  • System Memory – 2 to 4 GB DDR3
  • Storage – 16 to 32 GB eMMC flash + micro SD card
  • Video Output & Display Interfaces – HDMI 2.0 up to 4K @ 60 Hz, eDP 1.2 interface, YUV interface, 1x MIPI DSI interface
  • Video Decode – 4K VP9 and 10-bit H.265 video codec support up to 60 fps
  • Audio – HDMI, 3.5mm headphone jack, optical S/PDIF, built-in microphone
  • Connectivity – Gigabit Ethernet (RJ45) port, WiFi and Bluetooth
  • USB – 2x USB 2.0 host ports, 1x USB 3.0 port, 1x USB 3.0 type C port
  • Camera – 2x MIPI CSI interfaces
  • Debugging – 3-pin serial header
  • Expansion
    • GPIO female header
    • mini PCIe 2.1 M.2 slot
    • SIM card slot
  • Misc – RTC battery header; power, reset and recovery buttons; IR receiver
  • Power Supply – 12V DC
  • Dimensions and Weight – TBD

The board will support Android 6.0.1 and Ubuntu 16.04, and can achieve around 75,000 points in Antutu. I got all information above from the video embedded below.

There’s a WIP Wiki page for the board currently in Chinese only, based on support for their previous Firefly-RK3288 board, we should soon have pretty good documentation and software support in English.

What I don’t know is pricing, but T-chip is not one of the Chinese manufacturers trying to cut price with almost zero margin, which explains why they can provide decent support for their board. For reference Firefly-RK3288 board is selling in 2GB/16GB and 4GB/32GB configuration on GeekBuying for respectively $159.99 and $219.99, so I’d expect the new board to go for less than $200 / $250 based on the same configurations. The end of the video also gives the clue that the board will be launched on Kickstarter, I just don’t know exactly when.

Thanks to Nanik for the tip.

R-Box Pro 3G Android TV Box Review – Part 2: Android 6.0 Firmware

November 21st, 2016 97 comments

The vast majority of octa-core Android TV Boxes sold on the market comes with 2GB RAM, but Amlogic S912 based R-Box Pro TV box was interesting with its 3GB RAM option (aka R-Box Pro 3G), as I wondered if I would see any noticeable improvements during my tests with the extra RAM. We’ve already confirmed the the hardware comes with 3GB RAM using 2x 1GB + 2x 512MB RAM chips configuration in the first part of the review last month, and it’s now time to check out whether this translates to anything in Android, as well as go through the usual hard-to-get features to work like automatic frame rate switching and HD audio pass-through.

r-box-pro-3g

First Boot, Firmware Update, and First Impressions

One positive with the device is the four USB ports, so this time I did not need an USB hub at all, and connected a USB HDD, two RF dongles for an air mouse and gamepad, as well as a USB keyboard to take screenshots. I completed the hardware setup with Ethernet and HDMI cables, and plugged the power supply to boot the device. Boot time is rather slow compared to competitors at about one minute.

Click for Original Size

The launcher used is exactly the same as on Rikomagic MK22, and the list of apps is also quite similar with IPTV apps such as Mobdro, Netflix, FilmOn Live, and UkTVNow.
r-box-pro-app-list

r-box-pro-apps-list-2The setup is also exactly the same, so if you want to find out more about the interface and setup options you can read Rikomagic MK22 review, while you’ll find more details about the IPTV apps (Mobdro / Filmon) in MXQ Plus / M12N TV box review.

I had no troubles with the settings when configuring WiFi and Ethernet, and the system kept the video output resolution I set (3840x2160p60) even between reboot. Part of the 16GB flash is used for the operating system, and the user still get 11.38 GB to play with, and at the end of the review after installing apps and some copying files, I only had used 3.26 GB.

r-box-pro-storageYou can also see exFAT and NTFS file systems are supported as usual, and a FAT32 micro SD card could also be mounted.

about-mediabox-r-box-proThe “About Media” box section shows R-BOX Pro 3G runs Android 6.0.1 with Linux 3.14.29, no surprise here. The firmware is rooted. I received the box early October, and when I first boot up the device the firmware was dated in September, so I checked for firmware update. They’ve done something pretty stupid as they’ve included both UPDATE&BACKUP and WirelessUpdate apps in the firmware, which is sure to confuse customers. But basically UPDATE&BACKUP app is not configured and trying to get an OTA firmware update will results in “Check Failed! Check Your OTA Servier Argent” (sic), while WirelessUpdate app appears to be configured, but can’t get any update firmware from the server, probably because they did not bother to copy any firmware… Finally, I could find new firmware on GeekBuying, but again on for “USB Burning Tool” with IMG extension, so I decided to try some new SD card method with Amlogic IMG firmware in Linux and Windows, and I finally managed to flash the firmware without using Amlogic USB Burning Tool. It took me nearly a full Saturday to make it work, but at least now I know how to do.

Nevertheless, this is 2016, and OTA firmware update is now working on most TV boxes, even some cheaper ones, so manufacturers should not expect end users to work with tools reserved to factory workers…

I had no problems using both Google Play and Amazon Underground to install apps. The remote control worked well enough up to 8 meters, and I could turn on and off the box with it.

Power handling is properly implemented with power off and standby modes, but the latter is pretty much useless based on the power consumption values I got on my power meter (with all USB devices connected as shown in top photo):

  • Power Off – 0.0 watt
  • Standby – 6.4 watts (USB HDD still on, Box LED is red)
  • Idle – 6.2 watts (Box LED is blue)

The case top and bottom temperatures were  respectively 41 and 51 °C max after Antutu 6.x benchmark, and after 15 minutes playing Riptide GP2, they rose to 42°C and 60°C respectively. The game performance was constant over time, and about the same as on other Amlogic S912 with highest resolution settings, i.e. not perfect, but playable.

Since one of the first thing I do with a new box is to check for new firmware, not having OTA firmware update, nor a simple SD card or USB flash drive ZIP firmware is not a good way to start. Sadly, even after the frustration of flash a new firmware, I had sluggishness issues with some apps show the “App is not responsive window” aking to wait or kill the app a bit more often than I’m comfortable with, and as we’ll see below my Kodi experience was one of the worse with 4K videos and audio pass-through. I certainly did not feel any benefit of having 3GB RAM over 2GB RAM with this device, as I was hoping the extra read/write buffer for the storage might improve the performance, but the opposite happened, likely because of sub-optimized firmware.

4K and Audio pass-through in Kodi 17.0 and DRM Info

The firmware I used for review (October 13, 2016) comes with Kodi 17.0-Alpha3 built on July 31, 2016 with TVaddons installed. I connected to my video samples SAMBA share and started testing some 4K videos:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 (H.264, 30 fps) – OK
  • sintel-2010-4k.mkv (H.264, 24 fps, 4096×1744) –  OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265) – OK
  • MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC) – OK
  • phfx_4KHD_VP9TestFootage.webm (VP9) – Won’t play, stays in UI
  • BT.2020.20140602.ts (Rec.2020 compliant video; 36 Mbps; 59.97 Hz) – OK
  • big_buck_bunny_4k_H264_30fps.mp4 – Started well, but after 30 seconds or so the image intermittently froze from time to time
  • big_buck_bunny_4k_H264_60fps.mp4 – Not smooth, and audio delay (hardware does not support this type of video)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK (although video did not seem as sharp as usual)
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) –  OK
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – Not smooth
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – Won’t play, stays in UI
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Won’t play, stays in UI

Most people probably don’t have VP9 videos, but considering one of the key selling on Amlogic S912 over Amlogic S905 is hardware video decoding support for VP9, it’s quite an unexpected issue, especially it is working on other Amlogic S912 TV boxes I tested so far.

Unsurprisingly, automatic frame rate switching is not working either…
kodi-17-audio-pass-through

I continued testing Kodi with HDMI pass-through to Onkyo TX-NR636 AV receiver was quite a disaster:

  • AC3 / Dolby Digital 5.1 – Audio OK (Dolby D 5.1), but video not smooth
  • E-AC-3 / Dolby Digital+ 5.1 – OK
  • Dolby Digital+ 7.1 – PCM 2.0
  • TrueHD 5.1 – PCM 2.0
  • TrueHD 7.1 – PCM 2.0
  • Dolby Atmos 7.1 – PCM 2.0
  • DTS HD Master – Black screen and no audio
  • DTS HD High Resolution – Black screen and no audio
  • DTS:X – Black screen and no audio (not supported by Onkyo TX-NR636, but should normally be heard as DTS-HD MA)

The box supports Widevine Security Level 3 DRM, which should allow for SD playback of some premium video services, but not HD or UHD.

WiFi and Internal Storage Benchmark

I’ve copied a 278 MB file between the internal storage and a SAMBA server using ES File Explorer in both direction in order to estimate WiFi performance. R-Box Pro support 802.11n and 802.11ac WiFi, so I tested both on different routers, and the system achieved 1.4 MB/s throughput using 802.11n, and 2.0 MB/s for 802.11ac on average.

WiFi Throughput in MB/s

WiFi Throughput in MB/s

rbox-pro-wifi-802-11ac-serverThe chart makes is clear that neither 802.11n nor 802.11ac performance is very. I must note than in the case of 802.11ac download performance was much higher than upload performance averaging about 3.4 MB/s. The chart on the right shows both Download (Upload from TV box – top) and Upload (Download from TV box – bottom) shows the traffic shape for 802.11ac transfer. 802.11ac download shows the performance is not stable, but at least there are no stalls, but the upload shows mostly constant throughput with several 3 stalls during transfer, so the connection does not appear to be entirely stable.

I measure Internal storage performance with A1SD bench, and the eMMC flash used in R-Box Pro delivered 39.28 MB/s read speed, and 19.31 MB/s write speed. Not the best, but those values should be enough to have responsive firmware in most conditions. So the slow loading apps issue if most probably due to a firmware/software issue then a problem with the hardware itself.

R-Box Pro 3G System Info and Antutu Benchmark

The board name is q6330, exactly the same as Rikomagic MK22, so I’d expect the firmware between those models to be very similar. R-Box manufacturer releases different firmware with their 2GB and 3GB RAM version however. CPU-Z also reports Amlogic S912 is an octa-core Cortex A53 clocked at 1.51 GHz with a Mali-T820MP GPU. 3 GB RAM is detected, or more exactly 2810 MB taking into account the hardware buffers), with 11.38 GB storage available to the user.

r-box-pro-3gb-cpu-z

Click to Enlarge

I ran Antutu 6.x to verify the performance, and 39,846 points is about what we’ve come to expect from Amlogic S912 TV boxes, with some devices getting as high as 42,000+ points.

Conclusion

I was intrigued with R-Box Pro 3G because of its 3GB RAM, but I ended getting the worse Amlogic S912 TV box of the six models I’ve reviewed so far.  OTA firmware is not working, the company does not seem to have a webpage for firmware, so I had to look on the Internet to find something on GeekBuying, with only IMG firmware requiring some Windows tools, or building your own parser in Linux in order to flash it. Clearly not user friendly. Kodi 17.0-alpha3 is installed in the box, and the list of issues is impressive: Vp9 videos can’t play, some 4K H.264 @ 30 fps video won’t play smoothly, automatic frame rate switching is not working either, and I only managed to get audio pass-through in Kodi work for a Dolby Digital 5.1 with some DTS-HD videos just showing a black screen. WiFi performance is rather weak both using 802.11n and 802.11ac WiFi, and the apps are not always loading very fast, leading the system to ask whether to wait or kill the apps. I’m pretty sure I missed some issues, but needless to say the company has a lot of work to do to make it a worthwhile device.

Kingnovel provided R-Box Pro 3G for review, and resellers & distributors can contact the company via their website. Individuals should probably not buy the device at this stage, but you can still purchase it for about $70 and up on GeekBuying,and Aliexpress. Note that the 2GB RAM version is often sold side-by-side with the 3GB RAM version, and price starts at $66.

Rikomagic MK22 Review – Part 2: Android Firmware, Video & Audio in Kodi, Benchmarks…

November 7th, 2016 4 comments

Rikomagic MK22 is one of the many Android TV boxes powered by Amlogic S912 octa-core processor with typical hardware specifications such as 2GB RAM, 16GB flash, Gigabit Ethernet and dual band WiFi. I’ve already taken the box apart to check out the hardware in the first part of the review, so I’ll focus on the firmware, but I’ll keep it short focusing on typical problem areas, as I’ve already reviewed a bunch of other Amlogic S912 TV boxes such as Qintaix Q912 or Beelink GT1.

First Boot, Firmware Update, and First Impressions

After having connected all usual cables and  accessories include a 1TB USB hard drive, and RF dongles for my air mouse and wireless gamepad, I booted the device, and after around 45 seconds (typically), I got to the main launcher.

Click for Original Size

Click for Original Size

Since I received the device about a month ago, I decided to go to the UPDATE&BACKUP app to see if there was any OTA firmware update, and unfortunately, as you can see from the screenshot below online update was not enabled in the device with the error: “Check Failed! Check Your OTA Servier Argent” (sic).

update-backup-fail

So I went to Rikomagic download page, and I could find a new firmware, the latest USB burning tool, and instructions. It did not go very smoothly, but I still managed to flash the firmware, and I explained the issues I came across in details in the post entitled USB Burning Tool Still Sucks in 2016. Still that was a disappointment to have to go through this, as the vast majority of TV boxes now support OTA firmware update through the network or SD cards, a much more user-friendly way to upgrade the firmware. The company explained that my early sample did not support OTA firmware update, but it should now. I tried again UPDATE&BACKUP, and got the same error, until I found another firmware update app called WirelessUpdate.

It won’t detect a new firmware since I have RKM MK22_161031 firmware released a week ago, but it did seem to properly check the status from the OTA server, telling that was not new update.

I won’t go into much details about the settings, as you can check my other S912 reviews for all options, for example M12N review. HDMI CEC, Playback settings (HDMI Adaptation), and Power key definition were all present in MK22 firmware. I had no troubles with settings Ethernet, WiFi, and the system automatically set my TV to 2160p @ 60 Hz and kept it that way throughout. I did not have the typical HDMI CEC issue turning on my AV receiver against my will. So it appears Rikomagic fixed some of the issues I encountered in early S912 TV boxes.

about-mediabox-rkm-mk22

I could also enter Android Marshmallow settings, and access all usual options. A single unified 11.38GB partition is used for both apps and storage from the 16GB eMMC flash, and the system runs Android 6.0.1 on top of Linux kernel 3.14.29. The firmware is rooted.

The provide remote control worked fine for up to 8 meters, as further away some keys would be missed. I reverted to MINIX NEO A2 Lite air mouse for most of the review because its mouse mode and QWERTY keyboard make it so much easier in most Android apps.

I could also power on and off (long press) the system with the remote, and make it enter standby (short press), with the following power consumption numbers when all accessories, include a USB hard drive, are connected:

  • Power off – 0 Watt
  • Standby – 5.1 Watts
  • Idle – 6.2 Watts

Temperature wise the box top and bottom temperatures reach 44 and 52 °C max after Antutu 6.x benchmark, and after 15 minutes playing Riptide GP2, they rise to about 47°C and 59°C respectively. I could not notice any performance degradation over time in the game, and performance was the same as on other Amlogic S912 TV boxes.

After my initial frustration with having to upgrade the firmware using Windows based Amlogic USB burning tool, the device actually performance well, just like other entry-level Amlogic S912 TV boxes, with the advantage of having several bugs fixed (HDMI CEC bug gone, HDMI video setting constant, …). Google Play also worked with any problems and could install all apps I normally use for reviews.

4K Video & Audio playback in Kodi 16.1, DRM Info

While some Amlogic S912 TV boxes are pre-loaded with Kodi 17.0 (alpha / beta), Rikomagic MK22 comes with the stable version of Kodi 16.1, possibly with some tweaks, as well as pre-installed add-ons.

mk22-kodi-16-1
Again, I’ll be quick in this review, as Amlogic S912 video playback performance is well known.  So I’ve only tested 4K videos, and checked whether automatic frame rate switching and HDMI audio pass-through are working. All videos were playing through the Gigabit Ethernet connection from a SAMBA share, unless otherwise noted (HDD = played from USB hard drive).

4K videos are playing reasonably well, although 2 had some unusual issues:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 (H.264, 30 fps) – OK
  • sintel-2010-4k.mkv (H.264, 24 fps, 4096×1744) –  OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) – First time: Video exited early (after 2 to 3 seconds). Second time: OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265) – OK
  • MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC) – OK
  • phfx_4KHD_VP9TestFootage.webm (VP9) – OK
  • BT.2020.20140602.ts (Rec.2020 compliant video; 36 Mbps; 59.97 Hz) – OK
  • big_buck_bunny_4k_H264_30fps.mp4 – Started well, but after 30 seconds or so the image froze with the audio still playing in the background.
  • big_buck_bunny_4k_H264_60fps.mp4 – Not smooth, and audio delay (hardware does not support this type of video)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK (although video did not seem as sharp as usual)
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) –  OK
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – HDD: Not smooth
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – OK
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Plays but could be smoother.

Automatic frame rate switching is not working just like on other Amlogic S912 devices, even after setting it in both Kodi and Android (HDMI Adaptation).

HDMI audio passthrough works for 5.1 channel audio, and I could not detect any audio cuts during testing contrary to what happens on some other devices:

  • AC3 / Dolby Digital 5.1 – Audio OK, but video not smooth
  • E-AC-3 / Dolby Digital+ 5.1 – OK
  • Dolby Digital+ 7.1 – PCM 2.0, no audio
  • TrueHD 5.1 – PCM 2.0, no audio
  • TrueHD 7.1 – PCM 2.0, no audio
  • Dolby Atmos 7.1 – PCM 2.0, no audio
  • DTS HD Master – DTS 5.1
  • DTS HD High Resolution – DTS 5.1
  • DTS:X (not supported by Onkyo TX-NR636) – DTS 5.1

So if all you really is Dolby and DTS 5.1, MK22 should be good enough, but TrueHD and DTS HD audio formats are not supported, at least in Kodi.

MK22 support Widevine Level 3 according to DRM Info, which may be useful for some premium video streaming app. This DRM level is only good enough for SD resolution on Widewine “protected” apps, as Level 1 would be required for HD and UHD resolution.

Networking and Storage

In order to evaluate WiFi performance, I copy a 278 MBfile between the internal storage and a SAMBA server using ES File Explorer in both direction. As with many recent boxes, MK22 also experience an asymmetric performance between download and upload, with the latter about twice as slow. On average Rikomagic MK22 achieves 1.6 MB/s throughput using 802.11n, not a very high performance even for 802.11n, but what’s surprising is that all Amlogic S912 TV boxes are very closely tied for 802.1n WiFi performance, so there may be an issue with Amlogic SDK, or some other limitations.

Internal performance is also important for fast loading times and overall system performance, and the eMMC used in MK22 has very good performance with 63.65 MB/s read speed, and 20.23 MB/s write speed.

That means there should not be visible slowdowns due to I/Os (provided random I/Os are fast too), and indeed during testing I did not experience any slowdowns, and found apps to load rapidly. Somehow boot time could be a bit faster with such performance.

I also tested file systems support and found FAT32, NTFS, and exFAT file systems to be supported by the device.

Rikomagic MK22 System Info and Antutu Benchmark

CPU-Z reports Amlogic S912 clocked at 1.51 GHz, so Kudos to Rikomagic here, as they are the first to report the real CPU frequency of that processor. The board name is q6330, framebuffer resolution is set to 1920 x 1080, and there’s indeed 2GB RAM (1807MB due to hardware buffers), and 11.38 GB storage available to the user.

RKM-MK22 achieved 40,827 points in Antutu 6.x, a score in line with other Amlogic S912 Android TV boxes I’ve tested so far.

rkm-mk22-antutu-score

Conclusion

I found Rikomagic MK22 to be stable and working mostly as expected, with some bugs corrected compared to earlier S912 TV box models under reviews, but with limitations frequently found in entry-level Amlogic S912 TV boxes with lack of support for automatic frame rate switching and HD audio (TrueHD, DTS HD) pass-through in Kodi, as well as DRM limited to Widewine Level 3. WiFi 802.11n is reliable, but performance is a bit weak, although similar to what you get with other Amlogic S912 devices. Storage speed is very good which ensure fast loading times and a responsive system. A big let down was lack of OTA firmware update, as I had to run USB burning tool to upgrade the firmware, but the company told me that from now on OTA firmware will be provided.

Rikomagic MK22 TV box can be purchased on the company’s Aliexpress store for $93.90 including shipping, or quite higher than equivalent competitors products. The Android box is also listed on GearBest, but still shown as “out of stock”.

Beelink GT1 TV Box Review – Part 2: Android Marshmallow Firmware

October 24th, 2016 28 comments

I’ve previously reviewed other Amlogic S912 TV boxes such as M12N MXQ Plus or Qintaix Q912, but Beelink GT1 has the advantage of being quite cheaper at $56 and up, but still come with many of the same features as more expensive devices. I’ve already posted pictures, and checked out the hardware design in the first part of Beelink GT1 review, so in the second part I’ll report my experience with Android, including video and audio capabilities, hardware features testing, and some benchmarks.

First Boot, OTA Firmware Update, Settings, and First Impressions

The device comes with two USB ports only, so I connected a USB hard drive to one of the port, and a USB hub to the other with the RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, as well as a USB keyboard to take screenshots. I completed the setup by adding HDMI and Ethernet cables, and connected the power supply to start the system.

A typical boot will take 30 seconds, and brings you to the home launcher.

You’ll find a section with date & time, and weather for your city, icon to main app (Kodi, Browser, Play Store, File Manager, Settings…), and a section with favorites, which the first time is empty, but you can easily add or remove icons as I did in the screenshot above. You’ll also have access the more favorites on the left and right of the main screen. If you’ve connect a hard drive, you’ll also get the annoying “USB device connected” window(s) at each boot just like in NEXBOX A95X TV box.

Android_6.0_USB_Harddrive

I had received the box early September, but now we are close to the end of October, so one of the first thing I did was to go to the list of apps, and start UPDATE&BACKUP app to check for any Online (OTA) firmware update.

Good, so I could update 20160819 firmware to 20160902 firmware. It did not work the first time, as my USB hard drive was connected, but I repeated the update without USB mass storage devices connected to the device, nor a micro SD card, and it worked smoothly, and did not mess with my settings, nor the few apps I installed with Google Play at the time.
beelink-gt1-ota-20160930
I went to the app again, and it found another update, so I update to firmware 20160930. I would be extra nice, if this would be handled automatically, but that’s just a minor issue. The changelog is completely useless, as they just copy “1. Optimization system 2. Minor bug fixes” for each firmware update…

I did on more check, and this was the latest version when I started the review. But before testing Kodi a few days later, I checked one more time, and I found yet another version with the exact same changelog, but a new 20161022 version which I installed successfully.

beelink-gt1-ota-20161022

So the good news is that OTA firmware update is working fine, and Beelink is providing them fairly often at this stage. I’d also like it them to offer a detailed changelog the way Zidoo is doing.

The settings part is the same as on Qintaix Q912 Android TV box, except they’ve added HDMI CEC options, and removed “Power key  definition”
amlogic-cec-control
Some of the most useful options include:

  • Device
    • Network – WiFi, Ethernet, and VPN
    • Display
      • Screen resolution: Auto switch on/off, deep color mode on/off, 1080p24/50/60, 720p50/60, 4k2k 24/25/30/50/60/SMPTE, 576p50, 480p60, 1080i50/60
      • Screen position, Day Dream, HDR (Auto, On, Off)
    • Sound -> Digital Sounds -> Auto detection, PCM, HDMI, SPDIF
  • Preferences
    • HDMI CEC – See screenshot above
    • Playback settings – HDMI self-adaptation on/off (aka automatic frame rate switching)
    • More settings – Access to Android Marshmallow settings

My Onkyo AV receiver will detect Beelink GT1 through HDMI CEC, but as usual I can’t use the arrow keys on Onkyo remote to control the device. The Android TV box will also prevent me to turn of the AV receiver, even if HDMI CEC is turned off in the box. The only work around is to disable HDMI CEC (RIHD) in the receiver itself. It’s a bug common in all Amlogic TV boxes running Android 6.0.

about_mediabox_beelink-gt1The good thing with Beelink GT1 is once I configure video output to 4K 60Hz it will stay that way all the time, contrary to many other TV boxes, not only based on Amlogic or also other processors.

We can go to More Settings to access Android Marshmallow settings with all the usual options. The settings also report an internal 16GB partition, but it’s obviously an hard coded value, possibly to avoid some customer complaining about not getting 16 GB storage, but only 11 or 12 GB… The About Mediabox section shows Beelink GT1 runs Android 6.0.1 on top of Linux 3.14.29 as per About Mediabox section. The firmware is rooted.

The included infrared remote control works OK, but the range is limited to 4 to 5 meters.  I’ve still used an air mouse for most of the review, since that type of device is more suited to Android, and a keyboard is included.

I had no problems with Google Play store, and I could install all apps I needed for review. I also installed the free version of Riptide GP2 racing game through Amazon Underground app.

The power button on the remote control will let you turn off, enter sleep mode or reboot the device, and it works… most of the time. For some reasons, at one point the box would just reboot, when I select the Shutdown option, and I could reproduce the issue 3 times. However, later one, the problem completely disappeared and turning off the device worked 100% of the time. I cannot remember if this was done before or after applying the last firmware update (20161022). You can also turn on the device from your sofa using the remote control.

Power consumption is not too bad, but bear in mind that Beelink decided to keep USB and Ethernet on in standby mode:

  • Power off – 1.0 watt
  • Standby – 2.0 watts
  • Idle – 2.4 watts
  • Power off + USB HDD – 1.1 watt
  • Standby + USB HDD – 4.0 watts (USB HDD + Ethernet still on)
  • Idle + USB HDD – 4.4 watts

That’s an advantage if you download files in the background for example, but if you want to save power, then power off mode is recommended. Ideally, power off consumption should be a bit lower than 1.0 watt.

Beelink GT1 did not get overly hot during testing. The maximum top and bottom covers’ temperatures after Antutu were respectively 47 and 51 °C, and about 47°C and 59°C after playing Riptide GP2 for 20 minutes.

Based on several comments I had read last month, and earlier this month, about apps crashing, some green screen flickering, and even Kodi forums recommending to avoid Amlogic S912 TV boxes and giving the “Buggiest Android Kodi Box award of the quarter” to “any Amlogic S912 box running Android Marshmallow 6.0”, so I was expecting a lot of troubles with the device. However, my experience was actually pretty good, as the firmware was responsive, I did not experience apps crashing nor random reboot at any times, never saw the green screen issue, and as we’ll see below, Kodi worked reasonably well for a cheap device. So either I was lucky, or the firmware update since then, helped fixed many of the issues. This does not mean it’s perfect, as it still have HDMI CEC issues, small pointer at 4K resolution, and other small bugs.

Video & Audio Playback with Kodi 16.1, Antutu Video Tester 3.0, and DRM Support

Beelink GT1 comes pre-loaded with a version of Kodi, but I’m not sure which, as while in Google Play I saw a few apps needed some upgrade, and I just clicked on upgrade all, and I only saw too late than it would mean an “upgrade” to Kodi 16.1 from Google Play. But finally, I found it may not be a bad idea, as usually I test the pre-installed version of Kodi, but for that review I can see how Kodi 16.1 from Google Play works on an Amlogic S912 TV box.

beelink-gt1-kodi-16-1
Some piracy add-ons are installed in the box by default, and an installation from the Play Store, will not remove them. I first went to the settings to make sure Video->Playback->Adjust display refresh rate is set to Always, as I had already enabled HDMI self-adaption in Android settings.

I played all videos from a SAMBA share over Gigabit Ethernet, unless otherwise stated.

Starting with some 1080p (and 720p) videos from Linaro media samples, and Elecard:

  • H.264 codec / MP4 container (Big Buck Bunny) – 1080p – OK
  • MPEG2 codec / MPG container –  1080p – OK
  • MPEG4 codec, AVI container – 1080p – OK
  • VC1 codec (WMV) – 1080p – 1080p – OK
  • Real Media (RMVB), 720p / 5Mbps – OK (software decode)
  • WebM / VP8 – 1080p – Not smooth (software decode)
  • H.265 codec / MPEG TS container  – OK

Automatic refresh rate switching is not working as on most other Amlogic TV boxes. VP8 is not playing smoothly because it’s relying on software decide. More videos with various bitrates:

  • ED_HD.avi (H.264 / 10 Mbps) – Not smooth
  • big_buck_bunny_1080p_surround.avi (1080p H.264 – 12 Mbps) – OK, excepting while panning in some scenes due to 60 Hz video output. If I manually switch to 24 Hz, the video is smooth.
  • h264_1080p_hp_4.1_40mbps_birds.mkv (40 Mbps) – OK
  • hddvd_demo_17.5Mbps_1080p_VC1.mkv (17.5Mbps) – Could be smoother
  • Jellyfish-120-Mbps.mkv (120 Mbps video without audio) – OK

Not quite perfect, but pretty much the expected behavior on most Amlogic devices. Dolby and DTS audio testing was then performed using both PCM output (stereo downsampling) through my TV speakers, and HDMI pass-through via Onkyo TX-NR636 receiver. Kodi audio options only allow DTS and AC3 pass-through, and there was nothing about TrueHD, nor DTS HD.

Audio Codec in Video PCM 2.0 Output
(Kodi 16.1)
PCM 2.0 Output
(Video Player)
HDMI Pass-through
(Kodi 16.1 )
HDMI Pass-through
(Video Player)
AC3 / Dolby Digital 5.1 Audio OK, but slow video No audio  DD 5.1, but slow video OK
E-AC-3 / Dolby Digital+ 5.1 OK No audio OK OK
Dolby Digital+ 7.1 OK No audio PCM 2.0 & no audio Slow video, and no audio HDMI icon blinking on AV receiver
TrueHD 5.1 OK No audio PCM 2.0 & no audio OK (TrueHD 5.1)
TrueHD 7.1 OK No audio PCM 2.0 & no audio OK (TrueHD 7.1)
Dolby Atmos 7.1 OK No audio PCM 2.0 & no audio DD 5.1 with beep (the app switched to the DD 5.1 track in the video)
DTS HD Master OK No audio DTS 5.1 DTS 5.1
DTS 5.1
DTS:X (not supported by Onkyo TX-NR636) OK No audio DTS 5.1 DTS 5.1

So that’s clearly not as good as more expensive Android TV box, as Amlogic S912 does not include Dolby nor DTS license (required for stereo downsampling for most apps), but it’s still slightly better than most cheap TV boxes, as HDMI pass-through works for DTS 5.1 and Dolby Digital 5.1 in Kodi, and TrueHD also supported in other video apps like Video Player or MoviePlayer. I did not notice any audio cuts with HDMI audio pass-through, as I experienced in many other devices.

Time for some 4K videos:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 (H.264, 30 fps) – OK
  • sintel-2010-4k.mkv (H.264, 24 fps, 4096×1744) –  OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • Bosphorus_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) – OK
  • Jockey_3840x2160_120fps_420_8bit_HEVC_TS.ts (H.265) – OK
  • MHD_2013_2160p_ShowReel_R_9000f_24fps_RMN_QP23_10b.mkv (10-bit HEVC) – OK
  • phfx_4KHD_VP9TestFootage.webm (VP9) – OK
  • BT.2020.20140602.ts (Rec.2020 compliant video; 36 Mbps; 59.97 Hz) – OK
  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • big_buck_bunny_4k_H264_60fps.mp4 – Not smooth, and audio delay (not supported by S912 VPU)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) –  OK
  • 暗流涌动-4K.mp4 (10-bit H.264; 120 Mbps) – ~1 fps, lots of artifacts (not supported by Amlogic S912 VPU)
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – SAMBA: bufferring a lot; USB HDD: Slow motion
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – OK
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Plays but could be a bit smoother

So overall, 4K video playback is pretty decent on Beelink GT1.

Sintek-4k.iso & amat.iso Blu-Ray ISO’s samples, and MPEG2 1080i videos could play just fine. A 720p Hi10p video could play smoothly with subtitle and audio, but 1080p is not smooth, as on other Amlogic S912 TV boxes. Since Hi10p relies on software decode, you need more powerful hardware, and I expect Rockchip RK3399 based TV boxes to easily handle Hi10p 1080p videos, but not 4K ones.

I’ve also tested some 3D stereoscopic videos only to see if the device could decode them since my TV does not support 3D:

  • bbb_sunflower_1080p_60fps_stereo_abl.mp4 (1080p Over/Under) – OK
  • bbb_sunflower_2160p_60fps_stereo_abl.mp4 (2160p Over/Under) – Black screen, audio only
  • Turbo_Film-DreamWorks_trailer_VO_3D.mp4 (1080p SBS) – OK

I also tested a bunch of other videos including MKV, VOB/IFO, AVI, XViD/DViX, MP4, and FLV videos and I had no problem whatsoever.A full 2-hour 1080p H.264 movie could fully play from the SAMBA share without issues

Antutu Video Tester 3.0 benchmark reports 866 points, roughly the same as on other Amlogic S912 I’ve tested so far.

YouTube app could play videos up to 1080p.

WiFI & Ethernet Performance

I copy and paste a 278MB file between a SAMBA share and the internal flash using ES File Explorer in order to evaluate WiFi performance. Beelink GT1 achieved a lowly 1.7 MB/s on average with 802.11n @ 2.4 GHz, but a more respectable 4.36 MB/s with 802.11ac (434Mbps Link Speed). It should be noted that download and upload speeds are asymmetrical, and downloads reach about 6.0 MB/s using 802.11ac, and ~2.2 MB/s with 802.11n.

Gigabit Ethernet works pretty well, as shown with iperf full duplex results:

Miscellaneous Tests

Bluetooth

I could pair Beelink GT1 TV box () and Vernee Apollo Lite smartphone in order to transfer a few pictures. Smart Movement has no issue connecting and synchronizing data to my Bluetooth LE fitness tracker, and I could listen to audio through SPORTS-S9 Bluetooth headset.

Since the firmware is already rooted, so I tried Sixaxis app with PS3 Bluetooth game controller close as explained in the post entitled “How to Play Games in Android TV Boxes With a PS3 Bluetooth Controller“, and it worked perfectly. So Bluetooth appears to be working very well on that device.

Storage

NTFS and exFAT partitions on a 1 TB USB 3.0 Seagate hard drive could be mounted, but not BTRFS nor EXT-4 ones. a FAT32 micro SD card could also be mounted in read/write mode.

File System Read Write
NTFS OK OK
EXT-4 Not mounted Not mounted
exFAT OK OK
BTRFS Not mounted Not mounted
FAT32 OK OK

A1SD bench app confirmed results found in most Android TV boxes with USB 2.0 ports, with 30+ MB/s for read speed for both NTFS and exFAT file systems, but a much lower sequential write for exFAT (6.8 MB/s) compared to NTFS (22.37 MB/s).

Gaming

I played Candy Crush Saga with the air mouse, and as Beach Buggy Racing with the wireless gamepad are both games played perfectly, even with graphics set to the highest settings in the latter. Riptide GP2 had acceptable performance even with “highest resolution” setting, not quite as smooth as on devices with a better GPU, such as Xiaomi Mi Box 3 Enhanced, but as expect just the same as other Amlogic S912 TV boxes, and the best Amlogic S905 TV boxes. I played the game for 15 to 20 minutes, and performance was constant throughout.

Beelink GT1 Benchmarks

Let’s start with CPU-Z. Beelink has not updated the firmware to reflect Amlogic S912 is actually limited to 1.5 GHz (1.65 GHz in best case), but apart from that we have the same values as on other S912 TV boxes. The manufacturer is Netxeon (Beelink is their brand), and the board is named q201_9377.

Antutu 6.x results varied quite a bit, with the first run achieving only 37,013 points, and another run around one hour latter getting 41,287 points, or about the same as M12N MXQ Plus TV box. RAM speed tests seems to be especially variable on Amlogic S912 devices.
beelink-gt1-antutu-benchmark
Vellamo returned results slighly better to what I got with Qintaix Q912, namely 792, 1,488, and 2,858 points for respectively Metal, Multicore, and Browser benchmarks, against 787, 1,422, and 2,336 points for the Qintaix device. M12N did not manage to complete the Multicore test.

Conclusion

Beelink GT1 works relatively well for this price, with a responsive and very stable firmware, most features working just fine, Kodi 16.1 working with DTS and Dolby audio pass-through, very good storage performance, but of course you can’t expect the same level support as more expensive devices, so for example TrueHD and DTS-HD are not working, automatic frame rate switching neither, and there are still some bugs common to other Amlogic Android Marshmallow devices.

PROS

  • Stable and responsive Android 6.0 firmware
  • Good 4K video support for VP9, H.265 and H.264 codecs in Kodi 16.1
  • HDMI audio pass-through for Dolby 5.1 & DTS 5.1 i Kodi 16.1, plus TrueHD 5.1/7.1 in Video Player & MoviePlayer (and other video apps relying on Android APIs)
  • Fast eMMC flash leading to fast boot and app loading times
  • Good Gigabit Ethernet performance, and decent WiFi 802.11ac performance (with my setup)
  • Google Play Store works fine
  • Good Bluetooth support with file transfer, BT audio, Bluetooth LE, and Sixaxis controller (PS3 gamepad) all working
  • OTA firmware update, and frequent firmware releases (about once a month so far)
  • Support forums (with Beelink more or less active)

CONS (and bugs)

  • HDMI audio pass-through not working for TrueHD and DTS HD 7.1 in Kodi 16.1, Dolby Atmos and DTS-HD 7.1 not supported in other apps
  • Automatic frame rate switching not working properly in Kodi and other apps (e.g. Video Player)
  • Overall performance and user experience very similar to Amlogic S905 TV boxes, except for Android 6.0, VP9 and HDR support.
  • 802.11n WiFi performance under average (with my setup)
  • Potential issue with Shutdown not working all the time (it will reboot instead). N.B.: I can not reproduce it easily.
  • HDMI CEC bug keeps my A/V receiver on (when pressing the power button on the receiver), even when HDMI CEC is disabled (unless I disable CEC in the receiver itself)
  • DRM: Only supports Widevine Level 3
  • Dolby & DTS licenses not included (Only a problem for apps other than Kodi, for people not using HDMI or S/PDIF audio pass-through). This would require Amlogic S912-H (Dolby+DTS) or S912-B (Dolby only) processor
  • Minor – Mouse pointer quite small when 4K video output is selected
  • Minor – “USB device connected” window(s) always autostart at boot time when USB mass storage device is connected.

Beelink GT1 price makes it attractive compared to other Amlogic S912 devices, but you don’t already gain much compared to cheaper, and some would argue more stable, devices based on Amlogic S905 processor, beside an upgrade to Android 6.0, VP9 video decoding, and HDR support.

I’d like to thank Netxeon/Beelink for sending the review sample. Resellers and distributors can purchase in quantities directly with the company, while individual will be find Beelink GT1 on Amazon US for $66.97, GearBest for $55.99 with GBGT1 coupon, and from several sellers on Aliexpress for $59.99 and up.
