Xiaomi Mi Box (US) Android TV TV Box Review

February 12th, 2017 18 comments

Introduction

The Mi Box is the first Xiaomi product I have used. I received it beginning of December and have been using it regularly since then. I have received 3 updates which went through uneventfully. I was very pleased with this box. I ended up getting one for my in-laws and one for my 4 year old sons bedroom. The UI worked as expected. I have an Nvidia Shield Android TV, and the Mi Box complements it very well. Having Plex Server running on the Shield and Plex on the Mi Box is pretty fantastic to easily share content. Not to mention way more cost effective than putting a Shield in every room.

What’s Inside

The build quality is good. The power supply puts out 5.2v which is not typical.

I do wish it had more USB ports. A single USB is inadequate. I found myself swapping USB out frequently during testing. There is optical audio and it has the round form factor. Luckily the cable I had had the adapter attached to the end, and it worked fine. No Ethernet adapter is present either.

Android TV UI

For anyone unfamiliar with Android TV UI I took a few screen shots. Across the top in the first screen capture a recently used/suggestion line appears. The top line will update based on your usage games, TV shows, YouTube, news etc.

Not all apps populate this. HBO GO, Plex, Netflix, do update. Immediately below there is a MI Box Recommends section which is static.

I was able to disable it under setting > apps to unclutter the main screen. These screenshots were taken when I first plugged in the box. I personally like the UI of Android TV and appreciate that Google ensures all apps to work with remotes and a mouse/touchpad is not necessary.

Casting

Another thing that I was forced to use because DirecTV Now does not have an Android TV app yet, is the casting feature. I had it on the Shield but never really used it. Between casting my screen from my phone to most video apps I found it very easy to use. My son will navigate YouTube Kids on his tablet and cast to the TV. This is a feature you won’t find on most android boxes and I found it very convenient and easy to use.

Voice Search

During my usage and showing my son how to use the voice search I grew to like it a lot. Voice searching that is able to return YouTube, Netflix and other video apps is really convenient. My son is 4 and doesn’t speak very clearly yet but it does a good job of recognizing his voice allowing him to find the video’s he wants. (minecraft, lego, minecraft, lego, minecraft, lego) 🙂

Passthrough and Auto Framerate

I spent many many hours trying to find a good combination in Kodi/SPMC/TVMC/FTMC and couldn’t get it to work consistently. DTS only worked for me. I hope they resolve this with software in the future.

Benchmarks/Testing

This is not really fair but I performed a side by side comparison of 3DMark: Xiaomi Mi Box vs Nvidia Shield. I thought it would be interesting to see. Fear not, the Mi Box does well with light gaming. I had no problems playing games that didn’t require a controller.

Click to Enlarge

WiFi is fair at about 15Mbps on my busy Unifi 2.4 GHz network. I also have a 5GHz N built into my router and strictly using it for testing. I was able to get about 30 Mbps throughput. I still prefer a wired connection when possible and was able to use a USB to Ethernet adapter on the MI Box. I moved 2 files below one on 2.4ghz and one on 5ghz. I don’t have an AC network to test.

I ran a few other tests and info apps below.

While reviewing

So not all apps are available due to the restrictions of Android TV and Google necessitating the apps be remote friendly. But you might run into a situation where you want to side load. If you have a air mouse or some other hid device connected it’s not a big deal. In order for to launch them in the past you loaded sideload launcher from the play store, It allows you to see all apps regardless if they are Android TV optimized. It works and is pretty easy. While reviewing I ran across a pretty neat app. TV App Repo. It makes sideloading even better.  What it does is create a small app that is basically a shortcut to your side loaded non Android TV app. Now all the apps can be launched from main screen without navigating to the sideload launcher sub menu. It worked on the few I tested. On the community addition, there are a few apps that it hosts one of which was Amazon Prime video. But I didn’t have luck getting videos to play other than trailers.

Final Thoughts

I wasn’t going to perform any benchmarking on this box. I don’t think that it is relevant. But I knew it would be crucified. This box was in my opinion built to consume media and I think it does it very well. All the streaming media apps worked great. The only drawback is that HDMI passthrough and auto framerate switching did not work consistently enough in Kodi or Plex. Streaming from HDHomerun works well even over WiFi. Amazon Prime Video is missing from this box. I did try some other methods to watch and only was able to cast from a web browser successfully.

During testing I didn’t use Kodi much and stuck with the main streaming apps that are optimized for Android TV. I hope Koying, the maintainer of SPMC, a fork of Kodi, brings some love to the Mi Box in the near future or even the Kodi team.

If you’re not an audiophile this will make a great box to stream with and hopefully save some money. If you are an Audiophile the Mi Box complements the Nvidia shield on other TV’s where surrounds sound doesn’t matter.

I would like to thank Gearbest for sending a review sample and their patience while I reviewed it. I really like to use the products for a while and get a good feel for them. If you are thinking about getting a Mi Box, it helps CNX by clicking & purchasing through this link.

Voyo (V1) VMac Mini Apollo Lake Mini PC Review – Part 2: Windows 10

January 30th, 2017 2 comments

Voyo VMac Mini, also sometimes referred to just Voyo V1, is an actively cooled mini PC powered by Intel Celeron N3450 or Pentium N4200 Apollo Lake processor. I’ve received samples for both, and already taken pictures of the device and motherboard. So in the second part I’ll review the mini PC checking out system info, running some benchmarks on both, and see how it performs as an entry-level desktop PC.

Voyo VMac Mini Setup and System Information

Setup is pretty straightforward, as you just need to connect mouse and keyboard, Ethernet, the mini HDMI to HDMI cable, optionally the included USB WiFi dongle, the power supply, and finally press the power button to get to Windows 10 desktop logged in as “admin” user in about 30 seconds.

Click to Enlarge

Some Apollo Lake mini PCs support HDMI 2.0 video output, but this requires a DisplayPort to HDMI 2.0 bridge chip, which not included in Voyo VMac Mini’s board, so the system supports 1080p resolution up to 60Hz, and 3840×2160 up to 30Hz.

Click to Enlarge

4K video output will work, but by default the system will be set to 1080p60. Window will show a “non-optimal resolution” notification on the bottom right whenever you change resolution to 4K.

Click to Enlarge

The System Info window will show the device is running an activated version of Windows 10 Home 64-bit, and comes with 4.00GB (3.84GB usable) RAM and Intel Pentium CPU N4200 @ 1.10 GHz (or Celeron CPU N3450). However, Voyo may not be 100% in compliance with the hardware requirements for a discounted Microsoft license, as while it comes with 4GB RAM, and a 32GB eMMC flash, Windows is installed on the 128GB SSD instead.

I’ve also included a “Device Manager” screenshot for a bit more info about the peripherals and features.

Click to Enlarge

One of the first thing you may want to do is to remove some Chinese programs which are running in the background.

The two processes are called ldslite.exe and computerZservice.exe, and many websites report about those two from the ones saying they are safe, to the ones claiming they are adware, to the ones claiming both are very dangerous viruses, and you need to download their free software to remove them. I have not seen any ads, but I could remove both easily simply going to “Add or remove programs”, and removed the only program with a Chinese name which removed both processes.

Voyo VMac Mini Benchmarks

If you are interested in typical system benchmarks I’ve already reported about PCMark 8 , Passmark 8 & 9, and 3DMark results in the posts entitled “Voyo VMac Mini mini PC (Intel Pentium N4200) Benchmarks” and “Voyo VMac Mini mini PC Benchmarks with Intel Celeron N3450 Apollo Lake Processor“, so I’ll just add storage and networking benchmarks in this section.

The C: drive is the 128GB FORESEE SSD drive where Windows is installed, and both sequential and random performance is pretty good, and ever faster than the already pretty fast SSD found on Voyo V3 mini PC.The 32GB eMMC flash (D: drive) is not quite as good, and from a technical point of view, it was the right thing to do to install Windows on the SSD.

Voyo VMac Mini does not include a wireless adapter internally, but a 802.11n WiFi dongle is included. Since you may want to use your own instead, I have not tested WiFi, but only Gigabit Ethernet using iperf 2 for a 60 seconds full duplex transfer.

The results show download speed is OK, but if you need a device that handles heavy traffic in both directions simultaneously this will not work so well:

I repeated the test in one direction only:

Voyo VMac Mini User Experience and Usability Testing

The mini PC has done good so far, I did not experience many problems (I had USB problem at the beginning with some flash drives not recognized, but they seem to have gone). But the most important is to see how it would perform during use as a desktop PC and/or HTPC, so I’ve performed the following tasks:

  • Multi-tasking – Launching and using Firefox, Thunderbird, LibreOffice, and Gimp at the same time
  • Web Browsing with Firefox & Microsoft Edge
    • Loading multiple tab in Firefox with CNX Software blog
    • Playing a flash game  (Candy Crush Saga) in Firefox
    • Playing a 4K (VP9) YouTube Videos in Microsoft Edge
  • Gaming with Asphalt 8
  • Kodi 17.0 RC3 @ 4K videos using H.265 or H.264 codecs, 10-bit H.264 @ 1080p, and audio pass-through


The good news is that such machine can now perfectly be used a an entry level computer for multi-tasking such as reading email, browsing the web, and editing documents. Beside the incrementally faster processor over Braswell and Cherry Trail systems, the fast SSD and 4GB of RAM clearly help here. You’ll still see differences with faster machine while scrolling long web pages, and playing games. 4K YouTube videos are playing well in Microsoft Edge, and not too bad in Firefox with only a few frames dropped here and there. Asphalt 8 frame rate does really feel similar to what I experience in Atom x7-Z8700 or Celeron N3150 based mini PCs such as Beelink BT7 and MINIX NGC1. Kodi 17 is almost out, so I used Kodi 17 RC3 during testing, with automatic frame rate switching working well, for example a 4K @ 30 fps video will make the resolution switch from 1080p60 to 4K30 automatically, and H.264 and 10-bit H.265 videos are playing fairly well. VP9 videos however are extremely choppy and unwatchable in Kodi 17. If you have a lot of animes using 10-bit H.264 (Hi10p), th goods news is that the processor is fast enough to play such videos using software decoding. HDMI audio pass-through works for Dolby Digital 5.1 and DTS 5.1, but not for TrueHD instead playing PCM 2.0 or transcoding to Dolby Digital, and DTS HD with the platform only passing DTS 5.1.

Stress Test, Fan Noise and Power Consumption

Some mini PCs do no handle heavy loads very well, with CPU throttling occurring after a few minutes, even for devices with a fan. So I ran AIDA64 Extreme Stability Test to find out, as well as HWiNFO64 in sensor-only mode for a little over 2 hours to find out.

Click to Enlarge

The results are very good with no CPU throttling, the maximum temperature achieved was 89 °C, 16° C from the maximum Junction temperature (105 °C), and the Pentium N4200 processor was clocked at 1.6 GHz most of the time right between the 1.1 GHz “baseline” frequency and 2.5 GHz maximum burst frequency.

The system is not fanless, but the fan does not allow turn, as it depends on actual temperature, and the higher the temperature the faster the fan spins. GM1352 sound level meter placed at about 2 cm from the top of the case reported 50 dbA under light load, and either 52.5 dBA during AIDA64 stress test,  with burst up to 57.5 dBA during the same test, that would only last maybe 10 seconds. Fan noise is not too bad while browsing the web, although audible, but for any demanding tasks you’ll clearly hear it on the temperature rise enough.

Power consumption was 10.3 Watts without USB hard drive during the stress test, but there’s a design flaw in power off mode as USB ports still draw current, so with a USB 3.0 hard drive connected, power consumption is 2.0 Watts when the device is turned off, and around 1.0 Watts when I only leave the USB keyboard and mouse. Idle power consumption is 6.4 to 7 watts with USB HDD connected.

Conclusion

Voyo VMac Mini works as advertised, and performance is quite good with the Apollo Lake processor processor, fast SSD storage and 4GB RAM. I could perfectly see people using it as an entry level computer to browse the web, work with documents and spreadsheets and so on. People who want to run high load on the device should not worry about CPU throttling as the fan and heatsink take care of cooling the device even under stress. It’s obviously still limited when it comes to games, and it might not be the best price/performance for HTPC use, as while 4K H.264 and 10-bit H.265 videos can play,  4K output is limited to 30 Hz (HDMI 1.4), 4K VP9 is not working well in Kodi, and HDMI audio pass through is limited to Dolby abd DTS 5.1, and does not support Dolby TrueHD not DTS HD formats.

At the beginning I also had some issues with some USB flash drives (NTFS) recognized by the system, but not mounted (no file system detected), but the problem went away, maybe after a Windows 10 update, and I could not reproduce the issue anymore at the end of the review with any of the 3 drives I tested. Please note the mini PC does not include WiFi, nor Bluetooth, but a WiFi dongle is included in the package instead. There was also some crapware installed in Windows 10, but as indicated in the review it’s very easy to remove. I plan to test Linux with Ubuntu 16.04, but so far my attempts have not been successful. The BIOS find the bootable drive with Ubuntu, but when I select it, all I get is a black screen.

I’d like to thank GearBest & GeekBuying for providing the samples for review, with the former providing the Pentium N4200 version which they sell for $234.93 and the latter the Celeron N3450 version selling for $199.99. Both models can also be found on other online shops such as Amazon US and Aliexpress. Note that the version on Aliexpress is significantly cheaper because it only comes with a 64GB SSD. The custom SATA cable to add your own 2.5″ hard drive is only $2 extra if you select a bundle on the Aliexpress link.

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.

Click to Enlarge

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.

Click to Enlarge

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.

Click to Enlarge

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.

Click to Enlarge

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.

DRM Info apps shows Widevine Level 3 is supported.

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.

WiFi Throughput in MB/s – Click to Enlarge

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.

Thanks to Gabe for the tip.

Beelink SEA TV Box with Realtek RTD1295, HDMI Input and Internal SATA Bay Sells for $105 and Up

January 24th, 2017 5 comments

I’ve already reviewed two Android TV boxes powered by Realtek RTD1295 processor, namely Zidoo X9S and EWEAT R9 Plus. They are quite interesting devices as beside supporting video & audio playback nicely (minus 4K H.264 @ 30fps), they also serve as a personal NAS thanks to their SATA interface and OpenWrt operating system running alongside Android, as well as a HDMI recorder and streamer thanks to the HDMI input. Zidoo firmware is a little better, but it only comes with external SATA, while EWEAT R9 Plus comes with a neat internal 3.5″ SATA bay inside a metal case. The downside is that it’s quite expensive at $200 shipped. If you’d like a Realtek RTD1295 solution with a SATA bay, but would like something more cost effective, Beelink SEA TV box with might be for you.

Beelink SEA specifications:

  • SoC – Realtek RTD1295 quad core ARM Cortex-A53 processor @ 1.4 GHz with ARM Mali-T820MP3

Review of Ebox T8 V Amlogic S912 TV Box with SATA Bay – Part 1: Specs, Unboxing and Teardown

January 19th, 2017 9 comments

Last summer I reviewed Ebox T8-4, an Android TV box based on Amlogic S905 processor sold by entertainmentbox.com and geared towards the UK market. Although it had some of the typical issues with HDMI audio pass-through, I found the box easy to setup, and potentially interesting for UK viewers since popular IPTV apps were pre-installed. It also came with a SATA bay but for some reasons I never managed to have either a 1TV HDD or 128 GB SSD recognized by the system. Nevertheless, the box is now used full time by another person who seems to be quite happy about it, especially since it comes with an air mouse and a gamepad, and good support. The company has now sent me their updated model, Ebox T8 V, with very similar features but instead equipped with Amlogic S912 octa-core processor. Before checking the firmware, I’ll have a look at the hardware in the first part of the review.

Ebox T8-V Specifications

Apart from the SATA bay and VFD display, the specifications are pretty standard for an Amlogic S912 TV box:

  • SoC – Amlogic S912 octa-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3
  • System Memory – 2GB DDR3
  • Storage – 16GB eMMC flash, SD slot up to 32GB, and internal 2.5″ SATA bay
  • Video Output – HDMI 2.0 and RCA composite ports
  • Audio Output – HDMI, RCA stereo audio ports, and optical S/PDIF
  • Connectivity – Gigabit Ethernet, dual band WiFi 802.11 b/g/n/ac. N.B.: no Bluetooth listed in specs, but they sell a Bluetooth gamepad so it might be supported.
  • USB – 3x USB 2.0 ports (including one OTG port) + 1x micro USB port
  • Misc – IR receiver, power button, VFD display
  • Power Supply – 5V/3A

The box runs Android 6.0 operating system with SPMC.

Ebox T8-V Unboxing

Beside “T8 V SMART TV BOX” package I also got an air mouse (the same as last year), a EU to UK plug adapter, and something packaged with cardboard and tape.

Click to Enlarge

Let’s open that first… That’s a 1TB WD Blue hard drive, which means I should probably already be setup, and I would not need to use a separate computer to partition and format it a way supported by the box.


The air mouse remote is the same as last year (S77 Pro), and includes a standard IR side with IR learning function, mouse functionality…

Click to Enlarge

…as well as a QWERTY keyboard side. The battery compartment is located on the right side of the keyboard and takes two AAA batteries.

Click to Enlarge

The first thing I noticed when opening the main package was a piece of paper (top right below) reading:

Because the T8 V is operating on Android 6.0, you will need to adjust the settings a bit. Let’s go into Settings, then click on Video, go to the bottom and change Settings Level to Expert. Now go to the Acceleration Tab, then over to Allow Hardware Acceleration – Amcodec, and turn it off. You need to do this, because with the introduction of the new Android 6.0, Amcodec is no longer being supported, which can cause issues with the Ebox Media Center.

This could probably be useful to change those Kodi settings for other Amlogic S905X, S905D, and S912 TV boxes too. I’m not sure why it is not disabled by default in the firmware however.

Click to Enlarge

The rest of the package includes an IR remote taking two AAA batteries which you are unlikely to use at all if you have purchased the air mouse, a 5V/3A power supply, an HDMI cable, a HDMI cable, and of course the device itself.

Click to Enlarge

The front panel has a power button, as well as plastic cover hiding the IR receiver and VFD display. Two USB ports, the SD card slot, and a recovery button can be found on one of the sides, with the other ports on the rear panels including a USB OTG port (full size), a micro USB port market USB HDD, an optical S/PDIF audio output, 3 RCA connector for video, left and right audio, a HDMI 2.0 port, a Gigabit Ethernet port and the power jack. The gap under the box should allow for some cooling of the hard drive. If you want to connect the hard drive, you’ll need open the cover on the bottom of the case. There’s also a sticker with a MAC address starting with 00:11:6E and looking up to Peplink International Ltd.

Installing the hard drive is very easy and does not require any tool. Two clips hold the back cover to the case, and then you just need to insert the HDD in the bay, and push it to plug it into the SATA connector. Put the cover back, and you’re done.

Ebox T8 V Teardown

The first step to open the device is to loosen the four screws on the bottom of the case. This will allow you to remove the plastic cover on the front panel, and then push and slide the device to take it out of its outer shell.

Click to Enlarge

The board is called U PLUS V1.1, and features a heatsink covering Amlogic SoC. Foresee NCEMBSF9-16G eMMC flash is used for storage (16 GB), while two NANYA NT5CB256M16DP-EK chips are used for memory on the top of the board.

Click to Enlarge

Gigabit Ethernet is made possible thanks to Realtek RTL8211F Gigabit transceiver and HS2401 magnetics, and WiFi connectivity relies on an uncommon module, but I could not read the exact model. Since Amlogic S912 does not integrate a SATA controller, the board designer used GL830 USB 2.0 to SATA bridge. TM1628 chip takes care of the VFD display, and GL850G USB 2.0 hub adds a few extra USB interface required by the board.

That’s all for today. If you are interested, the box is for sale directly on Entertainmentbox.com for 104.99 GBP ($129.5) with the standard remote, and up to 217.97 GBP (~$269) with full options including a 1TB HDD, Rii i12 Keyboard, and an Ipega gamepad. The package I received should cost 185.97 GBP (~$229). Prices include VAT.

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.

Click to Enlarge

Click to Enlarge

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.

Click to Enlarge

Click to Enlarge

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.
