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

January 12th, 2017 8 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

  • 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) – 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.

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.

ASUS Tinker Board is a Raspberry Pi 3 Alternative based on Rockchip RK3288 Processor

January 5th, 2017 30 comments

Regular readers may remember MQMaker MiQi board, a $35 (and up) development board powered by Rockchip RK3388 quad core ARM Cortex A17 processor, based on Raspberry Pi 3 form factor, but much faster according to benchmarks. Sadly, the board’s crowdfunding campaign was not that successful, possibly because of the “its’ a 2-year old processor” syndrome. But now, Minimachines has found that ASUS has designed a very similar board, dubbed Tinker Board, with an extra WiFi and Bluetooth LE module, audio jack, MIPI DSI connector, and a few other modifications.

Asus Tinker Board specifications (bold highlights and strike-through show differences with MiQi board):

  • SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1
  • System Memory – 2GB LPDDR3, dual channel
  • Storage – 8 or 32 GB eMMC flash + micro SD slot
  • Video output & Display I/F
    • 1x HDMI 2.0 up to [email protected]
    • 1x 15-pin MIPI DSI supporting HD resolution
  • Audio – 1x 3.5mm audio jack; Realtek HD codec with 192KHz/24-bit audio
  • Connectivity – Gigabit Ethernet, 802.11 b/g/n WiFi, Bluetooth 4.0 + EDR
  • USB – 4x USB 2.0 host ports, 1x micro USB port (for power)
  • Expansion Headers
    • 40-pin “somewhat Raspberry Pi compatible” header with up to 28x GPIOs, 2x SPI, 2x I2C, 4x UART, 2x PWM, 1x PCM/I2S, 5V, 3.3V, and GND
    • 2-pin contact point with 1x PWM signal, 1x S/PDIF signal
  • Misc – Button, unpopulated fan header
  • Power Supply – 5V/2A via micro USB port
  • Dimensions – 85.6 x 54 cm

The company targets education, maker, and IoT markets for the board, with applications ranging from mini PC to portable game console and RC products like drones. The board supports Debian with Kodi.

asus-tinker-board-vs-raspberry-pi-3ASUS also provided a quick comparison table with Raspberry Pi 3 model B, that mostly shows the advantages over the Tinker board. The table is mostly fine, and I got some Phoronix benchmarks showing RK3288 can be about three times as fast as BCM2837 processor for FLAC audio encoding. The last row with officially supported OS appears to show both boards on the same footings, but Raspberry Pi 3 model B will have a clear advantage here, although I’m not sure why Asus did not list Android OS support for their board. The table does not include any price information either.

The only information I could find was from the Slideshare presentation above, and there does not appear to be any official website or page on Asus website.

Thanks to Freire for the tip.

There are two ways to download the images:

  • BitTorrent – 16.0 GB download with images for all boards
  • Main server (http) – 1.6 GB compressed firmware image for your board.

If you download from the main server, you’ll get a warning saying you can’t sell hardware pre-installed with the image:

RetrOrange Pi is a non profit project.
It consists of a basic Retropie setup with most Libretro cores on top of an Armbian Jessie Desktop version pre-installed.
It includes an OpenELEC fork as well.
Much of the software included in the image have non-commercial licences. Because of this,
selling a pre-installed RetrOrange image is not legal, neither is including it with your commercial product.
As it relies on other people’s work with our own features, we won’t be offering any help in customizations to avoid rebranding or reselling.

It will be interesting to see what happens with RetroEngine Sigma project on Indiegogo that is very likely based on RetrOrangePi image for Orange Pi Lite board.

Anyway, since BitTorrent download was very slow, I downloaded RetrOrangePi-3.0.Orangepione.img.tar.gz from the main server for my $3.69 Orange Pi One board (there was a promo in September), extracted it, and flashed it to a 32GB card (8GB is enough) in Linux:

Replace sdX by your own SD card device in the 3rd command above. You can also do this in Windows with Win32DiskImager. Once it is done, insert the micro SD card in your board or TV box, prepare a gamepad, and connect all relevant cables.

If you have connected the serial console (completely optional), or want to access the system through ssh, you can login with pi/pi or root/orangepi credentials:

Most people will just follow the instructions on the TV. We’ll get through a bunch of animation and logos during the boot.Note: Please ignore the vertical lines on the photos, as there’s just an issue with my TV.

retrorangepi-3-0-logo
The first time the system will resize the SD card to make use of the full SD card capacity, and generate SSH keys.
retrorangepi-installationOne more “Loading…” logo…

retrorangepi-loading

If you have connected a gamepad (highly recommended), you’ll be ask to configure the keys. Tronsmart Mars G01 gamepad was automatically detected, and I could easily set all keys up.

retrorangepi-gamepad-configurationOnce all is well and done, you’ll get to the main menu to select emulator or Kodi.

retrorangepi-user-interfaceMost emulators do not come with ROMs due to license issues, so you’d have to find the ROMs yourself, and install them via a USB drive, or copy them directly into the board over the network, for example with scp. If you want to try to play some games straightaway, you can do so by going to the PORTS sections with 13 games available including Doom, Quake, Wolfenstein 3D, CannonBall, Duke Nukem 3D, Super Mario War, etc…

I tested shortly tested Wolfenstein 3D and Quake, as well as launched Kodi 17 (Beta 6) in the demo video below.

Review of Mecool BB2 Pro TV Box with DDR4 Memory – Part 1: Specs, Unboxing and Teardown

December 16th, 2016 16 comments

Mecool BB2 Pro is yet another Amlogic S912 Android 6.0 TV box, but after Eweat R9 Plus, it’s my second TV box with DDR4 memory that should deliver much higher bandwidth compared to DDR3 memory used in most TV boxes. But so far, it’s clear how much performance can be extracted from the system with higher memory bandwidth in actual use,  and that’s exactly what I hope to find out in the second part of the review, but in this post I start by going through the specs, check the box and its accessories, as well as the hardware design.

Mecool BB2 Pro specifications

Apart from the DDR4 memory, BB2 Pro has pretty common specifications:

  • SoC – Amlogic S912 octo-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3 GPU
  • System Memory – 3 GB DDR4
  • Storage – 16 GB eMMC flash + micro SD slot up to 32GB
  • Video Output – HDMI 2.0a with HDR and CEC support up to 4K @ 60 fps, and AV port for composite output
  • Audio Output – HDMI, AV (stereo audio), and optical S/PDIF
  • Connectivity – Gigabit Ethernet, dual band WiFi 802.11 b/g/n/ac + Bluetooth 4.0
  • USB – 2x USB 2.0 ports
  • Misc – IR receiver, power button, recovery pinhole, LEDs
  • Power Supply – 5V/2A

The device runs Android 6.0 with Kodi pre-installed.

Mecool BB2 Pro Unboxing

Videostrong sent the package to me as Mecool is one of the brands together with YokaTV, and they are also found in some OEM products like Vontar.
mecool-bb2-pro-package
The device ships with an IR remote control with IR learning function requiring two AAA batteries, a HDMI cable, a 5V/2A power supply, and a user’s manual.

The device itself looks pretty similar since it’s based on the exact same case as YokaTV KB2 we’ve just reviewed, and all ports are the same including the front panel’s IR receiver and LED window and power button, two USB 2.0 ports and a micro SD slot on the side, and the rest on the rear panel: Gigabit Ethernet, optical S/PDIF, AV port, recovery pinhole, HDMI 2.0a output, and the power jack. There’s also an external Wifi antenna.

Mecool BB2 Pro Teardown

D0:76:58 MAC addresses used by Videostrong still do not look up to anything. [Update: The company told me that “The MAC we’re using is not IEEE MAC. It works in localized network, and it is the only id for empowering applications to activate, specially IPTV applications.”] Anyway, I had to remove the four rubber pads in the metallic bottom cover, and loosen the screws underneath in order to open the device.videostrong-bb2-pro-bottom-caseWe’ll find two Samsung K4A8G165WB-BCRC DDR4 SDRAM chip (8Gbit each) so we’ve not been lied too, and the device indeed has DDR4 memory :), as well as the marking (3.3V, Tx, Rx, GND) for the serial console on the bottom of the board.

We’ll need to use a small plastic tool to pull out the board from the plastic case. A heatsink – plus two thermal pads – covers Amlogic S912 processor and the remaining DDR4 chips, and a LED is connected to the bottom of the case. You’ll also notice an elliptic opening (unused) on the top right of the plastic, that’s probably reserved for a power button in other designs.

Samsung KLMAG1JENB-B041 eMMC 5.1 flash provides 16 GB of storage with theoretical 285/40 MB/s sequential R/W performance, while Realtek RTL8211F and Pulse H5009NL chips enabled Gigabit Ethernet, and a KM63350711 wireless module – whose naming reminds me of Ampak AP6335 – delivers 802.11ac WiFi and Bluetooth 4.0 connectivity. Finally DIO2133 audio driver completed the most noticeable components on the board.

I’d like to thank VideoStrong for sending the review sample, and interested distributors may inquire the company via the product page. Mecool BB2 Pro can also be purchased for $68 and up on Banggood, GearBest, and eBay, or just about the same as YokaTV KB2 with 3GB DDR3 instead of 3GB DDR4, and 32GB storage instead of just 16 GB, with the rest of the specifications being equal.

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

December 15th, 2016 10 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.

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.

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.

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.

yokatv-kb2-remote-control-configuration

Status Bar

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.

yokatv-kb2-kodi-audio-pass-through-settings audio-file-list-dts-dolby-truehd4K Video

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.

yokatv-kb2-custom-firmware-automatic-frame-rate-switching yokatv-kb2-custom-firmware-audio-pass-through yokatv-kb2-custom-firmware-video-codecsConclusion

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.

It’s Official: Selling Android TV Boxes with Piracy Add-ons/Apps Can Get You in Jail (in the UK)

December 12th, 2016 16 comments

A while ago, two persons in the United Kingdom decided it was a good idea to  setup a shop and sell Android TV boxes promising free access to premium content like the Premier League football matches with a one-time purchase of the hardware. Of course they did that with a TV box with some piracy add-ons and/or apps, and when The Premier League found out they brought a prosecution against the two.

android-tv-box-piracy-jailThe court case has been going on for several month, and the UK court has announced its verdict: The main accused was sentenced to four years in prison, while his associate pleaded guilty and received a two-year suspended prison sentence, both convicted for Conspiracy to Defraud.

That’s the first sentencing of IPTV boxes in England, and the Federation Against Copyright Theft (FACT)’d director declared that ” today’s result should send a hard-hitting message to anyone involved in selling illegally modified set-top boxes”. There’s no word to what will happen to customers of the boxes, which included individuals, but also businesses like pubs, but the article on Advanced Television appears to indicate the organization involved in the court case, FACT and the Police Intellectual Property Crime Unit (PIPCU) will focus on sellers rather than consumers.

Thanks to theguyuk for the tip.

First Intel Apollo Lake J3455/J4205 Processor Benchmarks & Video Tests

December 6th, 2016 23 comments

Many products powered by Intel Apollo Lake processors have already been announced, but few are actually shipping, and I have yet to get one here. However, AndroidPC.es got hold of ASRock J4205-ITX and J3455-ITX motherboards powered by respectively a Pentium J4205 quad core processor and a Celeron J3455 quad core processor, run a few benchmarks, and tested videos in Windows 10 on the motherboards with Kodi 17 and MPC-HC.

 

ASRock J4205-ITX Motherboard

ASRock J4205-ITX Motherboard

Let’s have a look at some of the benchmarks to better understand of what we can expect from Apollo Lake desktop processors.

pcmark-apollo-lake-processorFirst there’s not that much of a difference between Celeron J3455 (1,771 points) and Pentium 4205 (1,830 points) in PCMark Home Convetional benchmark, however you should clearly feel a boost in performance compared to systems with Intel Cherry Trail x5-Z8300 processor (1,141), and the score is getting fairly close to a mini PC with an Intel Core i3-5005U dual core / four thread processor (15 Watt TDP).

apollo-lake-benchmark-3dmark

If we look at 3D graphics performance, there are even more contrasts between various machines / processors. There’s a really big leap between MINIX NEO Z83-4 with x5-Z8300 processor and both Apollo Lake motherboards (150 to 165% better 3D performance), but on the other hand there’s a noticeable gap (almost 50%) between Intel HD 5500 graphics found in Core-i3 processors and Intel HD 500/505 graphics used in J3455 and J4205 processors.

AndroidPC guys also ran other benchmarks such as Cinebench, games fps, and so on, and I invite you to read their review (in Spanish) if you want to find out more. However, since there was some confusion about 10-bit HEVC and VP9 support, it’s interesting to also check out the video test results.

1080p “standard”
MPC-HC KODI 17
MPEG2 / MP2 2.0 – 6.6Mbps OK OK
MPEG4 / MP3 2.0 – 7.6Mbps OK OK
H264 / AAC 2.0 – 7.2Mbps OK OK
VC1 / WMA3 2.0 – 8.6Mbps OK OK
VP8 / VORBIS 2.0 – 7.8Mbs OK OK
1080p  – Higher bitrate 
Birds – H264 / No audio – 40Mbps OK OK
Samsung Oceanic Life – H264 – AC3 2.0 – 40Mbps OK OK
4K Videos
Skyfall – H264 / AAC 2.0 – 10Mbps OK OK
Timelapse – H264 / AAC 2.0 – 43Mbps OK OK
H.265/VP9 Videos
Tears of steel – HEVC 8bit / AAC 2.0 – [email protected] – 17Mbps OK OK
Beauty – H265 – HEVC 8bit / No audio – [email protected] (recorded @ 120 fps) – 12Mbps Skipped frames OK
Samsung UHD Dubai – HEVC 10bit / AAC 2.0 – [email protected] – 51Mbps Skipped frames OK
Google test – VP9 Youtube OK OK

So all videos can play in Kodi 17 even 4K 10-bit H.265 videos and VP9 videos, however MPC-HC appears to have issues with some H.265 videos. Both ASRock motherboards support HDMI 2.0 with up to 4K @ 60 fps, but none of the 4K H.265 videos had a framerate over 30 fps, so this would have to be tested. HDMI audio pass-through was not so great, as it only worked for Dolby Digital 5.1, not but TrueHD or DTS HD, possibly because the boards are equipped with a DisplayPort to HDMI 2.0 converter which could introduce issues.

There are some Linux benchmarks (Phoronix) for ASRock J4205-ITX board, but currently limited to C-Ray.

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

November 21st, 2016 91 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.

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.

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.
