Mecool KIII Pro Hybrid STB Review – Part 2: Android Firmware, TV Center, and DVB-T2 & DVB-S2 App

March 22nd, 2017 63 comments

Last year I reviewed K1 Plus T2 S2, an Android TV box powered by Amlogic S905 quad core processor with DVB-T2 and DVB-S2 tuner support, which worked with some caveats. VideoStrong has now send me an updated model with Amlogic S912 octa-core processor, which I presented in the post entitled Mecool KIII Pro Hybrid Android STB Review – Part 1: Specs, Unboxing and Teardown, where I listed the specifications, and showed photos of the device and the boards (main board + tuner board). I’ve now had time to play with the device, and in many respects the user experience is very similar to the one I got with KI Plus T2 S2 models, but there are also some tweaks, and a few bugs which I’ll report in the second part of the review below.

KIII Pro Hybrid TV Box Setup, Settings, & Power Consumption

The four USB ports are really convenient, as I could connect a USB hard drive, an air mouse, a wireless game pad, and a USB keyboard without the need for a USB hub. I also connected the usual Ethernet and HDMI cable, plus the cable from my Satellite dish to the DVB-S2 F connector, and the cable from my roof antenna to the DVB-T2 coaxial connector.

Once we connect the power, the device boots automatically, and usually takes under 30 seconds to do so. The launcher is pretty much the same as KI Plus TV box.

Click for Original Size

So I won’t go through it in details again, and will only comment on one change. Kodi is gone and been replaced by something called “TV Center”. So I clicked on it, and it showed a famous Chinese proverb “The installation isn’t installed!”. So I went to the list of apps, and click on TV CENTER, which will do the installation of this mysterious app.

Once it’s done I can click on TV Center, and the user interface looks familiar.

Click to Enlarge

So that means they made some modifications to Kodi 17, and change the name to comply with the trademark requirements.

Click to Enlarge

The TV Center installation also automatically added some add-ons as shown in the screenshot below.

Click to Enlarge

The Setting app is exactly the same as for other recemt Amlogic TV boxes, and there’s nothing specific to DVB, so I’ll mostly skip it (If you want to see check out Qintaix Q912 review), except to show Storage & USB section that reveals 634 MB is used out of 16.00 GB. That’s obviously a fake number, and it should be around 11 to 12 GB, but the company may have chosen to do so to avoid some customer’s complains that there’s not 16GB storage, as they don’t understand the OS take places on the flash.

Click to Enlarge

It also shows NTFS and exFAT file systems are supported, but not EXT-4, nor BTRFS.

The About section shows the model is indeed KIII pro running Android 6.0.1 on top of Linux 3.14.29. The firmware is rooted by default.

OTA update appears to be supported, but at the time of the review, there was no update available.

I tested the provide IR remote by adding two AA batteries, and it works well up to 10 meters. For most other TV boxes, I’d recommend to use an air mouse, bu in the case of KIII Pro, you’ll need to keep using the remote control in order to support DTV app for DVB-S2/DVB-T2 properly, maybe switching to an air mouse or wireless keyboard + touchpad for some other Android apps. One recurring issue in most TV boxes is still present in KIIIPro however: the mouse cursor is rather small when you set your TV to 4K resolution.

I could install all apps I needed through Google Play, and Amazon Underground without issues.

The set-top box has only two power modes: off or on, and there’s no standby mode. I can turn the device on or off using the IR remote control or the power button.

Power consumption is pretty high in power off, as I tested different options with or without the USB hard drive, but I found a lot of variability with testing:

  • Power off – Test 1: 5.1 Watt; Test 2: 2.2  Watts; Test 3: 3.1 Watts
  • Idle – 7.2 Watts, then 4.3 Watts (2nd try)
  • Power off + HDD – Test 1: 5.1 Watt; Test 2: 2.2  Watts; Test 3: 3.1 Watts
  • Idle + HDD – 9.3 Watts then 8.1 Watts (2nd try)

The good news is that USB ports are turned off in power off mode, so at least the extra power consumption does not come from those ports.

Temperature is a little higher than other boxes, but I’ve not encounter massive CPU throttling during my tests. After playing a 2-hour video the maximum top and bottom temperatures as measured with an IR thermometer were respectively 53°C and 57°C, while after playing Riptide GP2 for about 15 to 20 minutes the temperatures were 51°C and 57°C, but I did not notice any lower framerate in the game as the time went on. I quickly started CPU-Z after quitting the game, and the reported temperature in the app was a high 89°C, so in some conditions performance degradation due to high temperature might be possible, I just did not experience it during my tests. FYR, room temperature was around 30 °C during testing.

KIII Pro Android firmware feels very much like any other Amlogic S912/S905X TV boxes, and it was responsive without any critical bugs. The only small annoyances were the somewhat loud music during the boot animation, the small cursor at 4K resolution, and the relatively high power consumption in power off mode.

Video & Audio Tests with TV Center (Kodi), and DRM Info

As we’ve seen in the section above, Kodi is not installed per se, but instead the box comes with an installer for a fork of Kodi 17.0-RC3 called TV Center.

I enabled “Adjust display refresh rate” in Kodi settings,and started by playing 4K video over Ethernet from a Linux SAMBA share:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 – Not always smooth
  • sintel-2010-4k.mkv – 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, 24 fps) – OK
  • phfx_4KHD_VP9TestFootage.webm (VP9) – OK
  • BT.2020.20140602.ts (Rec.2020 compliant video) – OK
  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • big_buck_bunny_4k_H264_60fps.mp4 – The video plays in slow motion and audio delays (NB: 4K H.264 @ 60 fps is not supported by S912 VPU)
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – OK
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) – OK
  • 暗流涌动-4K.mp4 (10-bit H.264; 120 Mbps) – Plays at around 1 to 2 fps (expected since it relies software decode as S912 VPU does not support 10-bit H.264)
  • Ducks Take Off [2160p a 243 Mbps].mkv (4K H.264 @ 29.97 fps; 243 Mbps; no audio) – USB hard drive playback: Not smooth as on all other Amlogic TV boxes.
  • tara-no9-vp9.webm (4K VP9 YouTube video @ 60 fps, Vorbis audio) – OK
  • The.Curvature.of.Earth.4K.60FPS-YT-UceRgEyfSsc.VP9.3840×2160.OPUS.160K.webm (4K VP9 @ 60 fps + opus audio) – Plays, but not always perfectly smooth as with all Amlogic S912 TV boxes.

4K video capabilities are pretty much the same as on other Amlogic S912 TV boxes, except for HD.Club-4K-Chimei-inn-60mbps.mp4 that was worse than usual. Automatic frame rate switching is not working again as is the case on most other S912 boxes, except MINIX NEO U9-H.

Next up I enabled HDMI audio pass-through in Kodi, and since TrueHD is not part of the list, I also enabled Dolby Digital (AC3) transcoding.

Here are the results of my tests with Onkyo TX-NR636 receiver.

Video PCM 2.0 Output
(Kodi)
PCM 2.0 Output
(MX Player / Video Player app)
HDMI Pass-through
(Kodi)
AC3 / Dolby Digital 5.1 Audio OK, but video not smooth at all OK Audio OK (Dolby D 5.1), Video not smooth
E-AC-3 / Dolby Digital+ 5.1 OK OK OK (Dolby D 5.1)
Dolby Digital+ 7.1 OK Video not smooth, and audio cuts No audio
TrueHD 5.1 OK No audio Dolby D 5.1 (transcoding)
TrueHD 7.1 OK No audio Dolby D 5.1 (transcoding)
Dolby Atmos 7.1 OK No audio Dolby D 5.1 (transcoding)
DTS HD Master OK No audio No audio and black screen
DTS HD High Resolution OK OK No audio and black screen
DTS:X OK No audio No audio and black screen

That’s pretty bad if you plan to use HDMI audio pass-through, except for Dolby Digital 5.1 / AC3. The first video has often problem on Amlogic TV boxes in Kodi, but most AC3 video should work fine. A good news is that AC3 is working via MX Player, so if you receive live TV channels with AC3 audio through the DTV app, it should be able to decode AC3 audio properly, something that was not possible in K1 Plus T2 S2.

I also played a 2-hour video to check for stability. The first time, TV CEnter app crashed with the message “Unfortunately TV Center has stopped” after about 5 minutes, and my second attempt was not completely trouble free either, as the video stopped at around the 50 minutes marked, and the system went back to TV Center UI, but I could select the video again, was offered to resume from 49:21, and it could play until the end.

KIII Pro supports Widevine Level 3 DRM. That means no Netflix HD like on most competing Android media players.

DTV App for DVB-S/S2 and DVB-T/T2

Now to the most important features of KIII Pro hybrid set-top box: DVB-T/T2 and DVB-S/S2 tuner support. The box is using the same DTV app as on K1 Plus T2 S2 with only minor modifications. The first time you launch the app, you should get the following message indicating there aren’t any channels yet, and asking you to scan for channels.

Once you agree, you’ll be ask to select DVB S/S2 or DVB T/T2.

Click to Enlarge

I’ve gone with the latter first, and I’ll redirect you to the post entitled “How to Configure DVB-S2 and DVB-T2 Tuners in K1 Plus Android DTV Receiver” since the procedure is the same. I got 26 channels for my T2 scan, but somehow I got 30 channels on K1 Plus T2 S2. So I went to check the settings, and this time the Area Setting was already set to Thailand, either automatically, or it was done before sending the device.

Click to Enlarge

Anyway I could watch both HD and SD channels without any problems, and signal strength are quality are both at 100% or close to it all the time.

Click to Enlarge

The EPG looks exactly the same, and it still has problems with Thai encoding or font.

Click to Enlarge

But before testing other features, let’s configure our satellite dish. Press the Menu key on the remote control, select Installation,

and then DVB S/S2.

Click to Enlarge

You’ll be able to select your satellite from a list, or define your own as I showed in K1 Plus T2 S2 setup guide and review. I did not show Motor Settings last time, so I’ve taken two screenshots one showing DiSEQc 1.2 support…

Click to Enlarge

… and the other USALS support. I have not tested either since I don’t own a motorized satellite dish.

Click to Enlarge

Once you are happy with the setting go to Multi Scan menu to see your satellite list, and press the Blue button on the remote control to start scanning.

Click to Enlarge

I got 25 TV channels and 7 radios after selecting a Blind Scan and FTA (free-to-air) channels only. Last year, I got 55 TV channels and 5 radio with the same “Thaicom2” satellite. Go figure… Signal strength and quality are quite lower in my case at around 55% and 50% respectively. There are some channels without signal, just as with K1 Plus T2 S2.

One nice improvement is that you don’t need to select between DVB-T2 or DVB-S2 when you start DTV app, as all your channels are shown in the list.

I tried EPG scheduling to start playback or record video, and it works exactly like before.

Click to Enlarge

Click to Enlarge

So  I setup a few “timers, and watched a DVB-T2 channel live, and one minute before a schedule recording on MONEY channel (DVB-S2) the following window overlaid the video:

I did not press any button, and one the count down expire, it switched to MONEY channel automatically (good), and I got the message “recording complete” (bad). I could reproduce this bug several times. I noticed if I schedule a recording on a channel, and stay on that channel it will work fine.

Click to Enlarge

You can see the list of recording above on my USB hard drive with some started manually (REC key on remote), and several scheduled. All the 0 bytes videos are due to the bug described above. So schedule does not work 100% reliably. However I noticed different current times (shown in top right of EPG) with different channels, for example it was 13:10 on a DVB-T2 channels, and 13:18 on a DVB-S2 channel, so this might explain some of the issues.. Please note that if you schedule program, and turn off the box, it won’t automatically start to record, and some comments in case try to run DTV app in the background and do other things. The DTV app must run in foreground in other to record videos.

I was more lucky with TimeShifting. Pressing the play/pause key on the remote control, will ask you to select a storage device, and you’ll be able to pause and play live TV within a default 5 minutes period, but this is adjustable in the settings. Note that you need external storage, as this won’t work from the flash.

Advanced users will be able to access CCcam, BISS, and PowerVU setting, by pressing the Menu key, selecting Installation and DVB S/S2, and from there enter 111111 on the remote (6 times character 1) to access Smart Data Manager menu.

Click to Enlarge

I have not done a video again since it’s so similar to the previous model, with just a few minor changes to the user interface, and if you want to check out DTV app into more details, I invite you to watch K1 Plus T2 S2 video review.

Networking (WiFi & Ethernet)

I’ve checked WiFi performance by transferring a 278 MB file between a SAMBA share and the internal flash (and vice versa) using ES File Explorer. I’ve only tried 802.11ac (connected @ 265 Mbps) , and again performance was asymmetric with the download @ 3.70 MB/s and upload @ 1.44 MB/s, and average @ 2.1 MB/s which makes it similar to other recent Amlogic TV boxes.

Throughput in MB/s

However, last time I reviewed MINIX NEO U9-H which had disappointing WiFi results with the same tests, as it was much slower than MINIX NEO U1 despite ahving the same WiFi module and overall system setup. MINIX them showed me their own tests with different routers showing similar performance between NEO U1 and NEO U9-H, so Amlogic may have completely blown up their SAMBA implementation in their Android 6.0 SDK (NEO U1 runs Android 5.0, U9-H runs Android 6.0).

For that reason, I also tested 802.11ac download speed using iperf “download” test:

That’s 216 Mbps (~27 MB/s) with a raw TCP transfer, and while SAMBA is not supposed to be the fastest network protocol, performance should not drop as low as 3.7 MB/s (over 7 times slower) for the SAMBA download unless something is really wrong.

I also tested Gigabit Ethernet with iperf but using a dual duplex test, and performance is fine.

Doing a SAMBA download over Gigabit Ethernet gets a 885 MB file transfer in 59 seconds (15 MB/s) to the internal flash, which is pretty much normal. So it looks like the issues occur when combining WiFi with SAMBA. SAMBA performs fine with Ethernet, and WiFi raw TCP transfer speed is OK.

Storage

KIII Pro supports exFAT, NTFS, and FAT32 file systems, but not EXT-4 and BTRFS. Benchmarks with A1SD bench shows you should avoid exFAT to record videos with the DTV app, as write speed is rather low (1.35 MB/s), and the write speed (156.09 MB/s) is just incorrect as it is what triggered the “Cached read” in the screenshot below.

Click to Enlarge

That means your only option is to use NTFS for external storage if you want to support larger video files. Performance is good at 44.43 MB/s for read speed, and  16.74 MB/s write speed.

The eMMC flash (“SD card” in screenshot) performance is not outstanding, but at 41.34 MB/s (read) and 18.29 MB/s (write) is good enough for the system to boot fast, and feel responsive at all times.

KIII Pro Benchmarks

CPU-Z correctly reports an octa-core ARM Cortex A53 processor @ up to 1.51 GHz with an ARM Mali-T860 GPU. Model KIII Pro is using q20x board, and the pp shows with 2825 MB total RAM, and 11.87 GB internal storage (the real value, but the 16GB shows in Android settings).

Click to Enlarge

Since I’ve reviewed so many Amlogic S912 TV boxes, and only ran Antutu 6.x benchmark to make sure there was no hidden issue, and the 40,330 points achieved by the TV box is within the normal range.

Conclusion

KIII Pro comes with typical performance and flaws of other Amlogic S912 TV boxes, with Android 6.0 firmware working well, TV Center (Kodi 17 fork) playing 4K videos relatively well, supporting DD 5.1 pass-through, but not the full range of audio codec, and lacking support for automatic frame rate switching. The device is however unique thanks to its dual tuner with DVB-T/T2 and DVB-S/S2 inputs, and the DTV app is about the same as on the previous model (K1 Plus T2 S2), but merges channels from both sources instead of having to choose at launch. Sadly some of the same bugs and shortcomings linger such as font encoding issues, and inablity to run PVR process in the background.

PROS

  • Stable and Responsive Android 6.0 firmware
  • Decent 4K video playback in TV Center (Kodi fork)
  • Support for Dolby Digital 5.1 (AC3) HDMI pass-through and downmixing in all apps
  • DVB-S/S2 & DVB-T/T2 support via DTV app with timershifting, EPG, and PVR support
  • Good 802.11ac WiFi and Ethernet performance
  • OTA firmware update (App is there, but not fully tested as no new firmware available during the review)

CONS (and Bugs)

  • DVB issues and shortcomings:
    • DVB S/S2 signal strength and quality is only around 50 to 55% (on my setup and for others too), which could lead to problems get signals for some channels
    • Thai font encoding issues
    • In some conditions, scheduled recordings will start on time, but stop immediately resulting in an empty video.
    • PVR function does not work in background, so the DTV app must be on the foreground at all time, and the box cannot be turned off when using schedules/timers.
  • HDMI audio pass-through not working (in TV Center) for Dolby Digital+ 7.1, TrueHD and DTS / DTS-HD
  • Automatic frame rate switching is not working in Kodi
  • Potential instability issues with TV Center – The 2-hour video test failed twice: 1st time: crash after 5 minutes; 2nd time the video stopped after about 50 minutes, but I could resume. N.B.: I did not experience other crashes while testing video samples.
  • Mediocre WiFi + SAMBA performance like in other S905X/S912 TV boxes with Android 6.0.
  • Relatively high power consumption (2.2 to 5.1 Watts) in power off mode
  • While I have not noticed obvious CPU or GPU throttling during my tests, temperature does get high (89 °C reported in CPU-Z)
  • Minor issues – Very small mouse pointer @ 4K resolutions, loud music during boot logo

Finally, I also have a user-friendliness remark. If you are just going to use TV Center and DTV app, the provided IR remote control will do, but if you are going to also use other Android apps, I normally recommend to replace the IR remote control with an air mouse. It’s not really possible/practical with KIII Pro, as DTV app has been designed around the IR remote control with keys such as MENU, PVR, REC, EPG… That means you’ll need juggle with both the IR remote control and an air mouse in order to fully enjoy all capabilities of the device. It would be really nice if VideoStrong could come up with an (optional) air mouse with keyboard that also supports DTV app.

Resellers and distributors may inquire Videostrong via their Alibaba page to purchase KIII Pro in quantities. Individuals can purchase KIII Pro Android set-top box on  GearBest ($117.99), Aliexpress ($141 and up), Banggood ($133.99), and other online retailers.

$44 A5X Plus Mini TV Box Runs Android 7.1 on Rockchip RK3328 Processor

March 15th, 2017 17 comments

Rockchip introduced RK3328 processor for TV boxes at CES 2017. The processor is based on a quad core Cortex A53 processor and a Mali-450MP is some other competitors such as Amlogic S9xx series, but what made the processor stand out is that it already supports Android 7.1, and includes a USB 3.0 port. A5X Plus Mini is one of the first TV box based on the processor, and the first “Chinese” TV box I’ve seen running Android 7.x Nougat.

A5X Plus mini specifications:

  • SoC – Rockchip RK3328 quad core Cortex A53 processor @ 1.5 GHz with Mali-450MP GPU
  • System Memory – 1GB RAM
  • Storage – 8 GB eMMC flash + micro SD card
  • Video & Audio Output – HDMI 2.0a up to 4K @ 60 Hz with HDR10 and HLG support, 3.5mm AV port with composite video and stereo audio
  • Video Codec – 4K VP9, H.265 and H.264. 1080p VC-1, MPEG-1/2/4, VP6/8
  • Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi
  • USB – 1x USB 2.0 port, 1x USB 3.0 port
  • Misc – IR receiver, power LED
  • Power Supply – 5V/2A
  • Dimensions & Weight –  TBD (Fits in hand)

The box runs Android 7.1 with Kodi 17.1 pre-installed, and ships with an HDMI cable, a power adapter, an IR remote control, and a user’s manual in English. Sadly the Fast Ethernet makes the USB 3.0 port advantage pretty much useless, as the bottleneck will be the network.

Since it’s a new processor with a new Android SDK, I’d expect a few issues at least in the first months. If you are interested in the device, you can purchase it for $44 including shipping on Aliexpress.

The box runs Android 6.0 with Kodi 17 pre-installed.

KIII Pro Unboxing

I received the device in a white retail package marked “KIII Pro Octa-core Hybrid STB” and “OTT TV BOX”.

The bottom of the package has some of the specs.The set-top box ships with a 12V/1A power supply, a largish IR remote control taking two AA batteries, an HDMI cable, and a user’s manual in English.

Click to Enlarge

The enclosure is very similar to K1 Plus with the edges “smoothed” out.

Click to Enlarge

The power bottom can conveniently be found on the top cover, one side has four USB 2.0 host ports, a micro SD, and the rear panel features a DVB-T2 coaxial connector, a DVB-S2 F connector, CVBS/LR composite + stereo audio 3.5mm jack, a Gigabit Ethernet port, a HDMI 2.0a port, optical S/PDIF, and the power jack.

KIII Pro Teardown

Let’s open the thing. We’ll have to start with the bottom cover. First we’ll notice a D0:76:58 MAC address which is not registered with IEEE, but the company previously explained that it was for “localized network, and it is the only ID for empowering applications to activate, specially IPTV applications”. Then, the box can be wall-mounted via two “hooks”, which can be convenient in some use cases. Finally, there’s a recovery pinhole on the right of the sticker in order to reinstall firmware if your box does not boot anymore.

Click to Enlarge

We don’t need to remove all rubber pads, as there are two just screws holding the case together. One under the bottom left rubber pad, and one under the QC sticker, which you need to pierce through. Once we’ve removed those two screws, the box comes apart easily.


We have two boards: main board with heatsink on the CPU, and a yellow board with the tuner circuitry.

Click to Enlarge

We’ll find two SpecTek DDR3 SDRAM chips: PE029-125 (512 MB) and another chip market “512X16DDR3” (1 GB) for a total of 1.5 GB RAM on this side of the board. The flash is covered by a sticker, which I have not removed, so we’ll see how storage performs in benchmarks. Gigabit Ethernet is done using Realtek RTL8211F transceiver, and Pulse H5900L transformer, while AC WiFi  and Bluetooth LE is implemented via a module marked “KM63351412” which could be equivalent to AP6335 module found in some other devices. Other chips include GL852G USB hub, and DIO2133 audio driver. If you want to hack the board, the serial console should be available via an unpopulated 4-pin header on the bottom left of the photo above.

Click to Enlarge

The other side of the CPU board comes with a micro SD card slot, and 1.5 GB extra RAM to bring the total to 3GB. We can also see extra cooling with a thick metal plate, covered by a black sheet, itself covered by a thin plastic transparent sheet on the bottom of the enclosure.

Click to Enlarge

S2&T2_R848_REV1.2 tuner board looks very similar to KI Plus tuner board, but just upgraded from Revision 1.0 to Revision 1.2, and featuring the same Availink AVL6862TA DVB-C/T/T2 + DVB-S/S2 demodulator, but they changed Rafael Micro R848 tuner chip to R912 model, which is not documentation on Rafael Micro website yet.

If you are interested in purchasing KIII Pro in quantities, you may inquire Videostrong via their Alibaba page. Mecool KIII Pro can also be purchased online on sites such as GearBest ($117.99), which by the way currently has promotions for their 3rd anniversary, as well as several shops on Aliexpress ($141 and up) and Banggood ($133.99).

Review of MINIX NEO U9-H Media Hub & MINIX A3 Air Mouse – Part 1: Specs, Unboxing and Teardown

February 24th, 2017 14 comments

MINIX showcased MINIX NEO U9-H TV box at IFA 2016 last year, but was not ready to launch the product or provide the full details yet. The company has now completed development of their Amlogic S912-H octa-core TV box, and sent a review sample for evaluation on CNX Software together with their latest MINIX A3 air mouse with voice command function. I’ll start by listing the specifications of the TV box, take some pictures, and tear it apart to check out how it’s been designed in the first part of the review, and test the firmware in the second part which I intend to post in a few days.

MINIX NEO U9-H Media Hub specifications

One of the main difference over other Amlogic S912, is the -H suffix which means Dolby and DTS licenses have been paid for so all apps will handle those audio formats:

  • SoC – Amlogic S912-H octa-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3
  • System Memory – 2GB DDR3
  • Storage – 16GB eMMC 5.0 flash, and micro SD card slot
  • Video Output – HDMI 2.0 up to 4K @ 60Hz with HDMI CEC, and HDR support
  • Audio I/O – Via HDMI output, optical S/PDIF, 3.5mm headphone jack, 3.5mm microphone jack
  • Connectivity – Gigabit Ethernet, WiFi 802.11 b/g/n/ac 2×2 MIMO, Bluetooth 4.1
  • USB – 3x USB 2.0 ports, 1x micro USB OTG port
  • Misc – IR receiver, power button, Kensington Lock
  • Dual DRM Support – Play Ready 3.0 + Google Widevine Level 1
  • Power Supply – 5V/3A

The device runs Android 6.0.1 with XBMC MINIX Edition. The box does not officially support Netflix, but this apk likely based on a previously reported Netflix hack, should give you better quality than the Netflix app from Google Play.

I’ve received the box and air mouse in familiar looking packages (if you’ve ever bought anything from MINIX).

The TV box has exactly the same shape as previous model, and ships with a WiFi antenna, a HDMI cable, a USB OTG adapter, a micro USB to USB cable in case you want to connect the box to your computer, a 5V/3A power adapter, a MINIX IR remote control, and a user’s manual in English, German, and Chinese.

The front of the device has a plastic window for the IR receiver, and the power LED, while one of the side includes the power button, three USB 2.0 host ports, a micro SD slot, a micro USB OTG port, and a Kensington lock. The rest of the ports can be found on the rear panel: 3.5mm headphone jack, 3.5mm microphone jack, HDMI 2.0a output, optical S/PDIF, Gigabit Ethernet, and the power jack.

You’ll also find the recovery pin hole on the bottom of the case, more exactly on the left side on the picture below.

MINIX NEO A3 Air Mouse

NEO A3 air mouse specifications include:

  • Connectivity – 2.4GHz transmission with up to 10 meters range
  • Sensors – 6-axis gyroscope and accelerometer
  • Remote side and QWERTY keyboard side
  • Built-in microphone for voice input.
  • Power – 2x AAA batteries
  • Support for Android, Linux, Mac OS X, and Windows

The remote ships with a user’s manual in English, and an RF dongle located in one of the two battery compartments located on the keyboard side.

Click to Enlarge

It’s actually very similar to MINIX NEO A2 Lite I’ve been using in all of my reviews for about a year.

MINIX NEO A2 Lite (Left and Top) vs NEO A3 (Right and Bottom) – Click to Enlarge

The main difference on the remote side is the microphone & settings button in the new model replacing respectively the “enter button”, which I never use since the Android button does the same, and the mute button. The keyboard side is very similar, except for some adding characters on the arrow keys.

The remote fits well in bigger hands, and I’m overall happy with my experience with A2 Lite, but I wish that space, dot, and enter did not have alternate keys, as I often have to press the Fn button to switch between mode. For example typing an IP address is not that convenient, but one the other side I understand space is limited on such keyboard, and you may have to compromise. The air mouse works well with MINIX devices, and can also be used with other devices, except that you can’t turn on TV boxes from other brands with the remote. This would require some IR learning function which has not been implemented.

MINIX NEO U9-H Teardown

Opening NEO U9-H is straightforward, as you just need to remove the four rubber pads on the bottom of the enclosure, and loosen four screws.

Click to Enlarge

The bottom of the board includes two SkHynix H5TQ4G63CFR-RDC DDR3 SDRAM chips (1GB RAM), the recovery switch, and a 3V battery for the real-time clock (RTC).

It’s then very easy to complete take out the board, as you can simply pull it out. MINIX is always serious when it comes to cooling, and again they’ve used a large heatsink in their latest model, which means there should be no CPU or GPU throttling issue. The two wireless antennas are connected to u.FL connector with some glue to keep them in place during transport.

The heatsink has a thermal that fits right on top of Amlogic S912-H SoC, which on the top of the board is connected to two more  SKHynix chip brings the total memory to 2GB, and a 16GB Samsung KLMAG1JENB-B041 eMMC 5.1 flash with 285/40 MB/s read/write sequential performance, and 8K/10K random R/W IOPS, so I/O performance should be very good.

Click to Enlarge

Network connectivity is achieved via a Realtek RTL8211F transceiver, and a RJ45 jack with built-in transformer, as well as the same Ampak AP6356S wireless module found in MINIX NEO U1, and supporting 802.11 b/g/n/ac WiFi up to 867 Mbps (2×2 MIMO) and Bluetoth 4.1 LE. Other components include Genesys Logic GL852G USB 2.0 hub controller, ES8323 audio codec, and Nuvoton MINI54ZDE ARM Cortex M0 MCU to handle power controls. wjhich were also used in NEO U1 TV box. MINIX also kept the same debug headers with JDEBUG1 with 3.3V/Tx/Rx and GND, ICE1 possibly for Nuvotron MCU, and JUART1 with Tx/Rx/GND. So the hardware looks just as solid as in NEO U1, and the eMMC flash that has been upgraded to a new and faster model, which should help a bit with boot time, apps loading times, and overall performance.

That’s it for the hardware, we’ll have to see if firmware is working as well as on their MINIX NEO U1 model, and I’ll publish a review sometimes next week after completing testing.

MINIX NEO U9-H will be officially released on Friday March 3, with pricing as follows:

  • MINIX NEO U9-H = US$139.90 / 154.90EURO
  • MINIX NEO A3 = US$34.90 / 39.90EURO
  • MINIX NEO U9-H + NEO A3 = US$159.90 / 174.90EURO

GearBest has already listed the device on their site, but it’s currently out of stock, since it will only launch in one week. However, MINIX also told me they had some limited stocks in their Amazon US, Amazon UK, and other Amazon stores.

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

  • 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.

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 10 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.

Click to Enlarge

Click to Enlarge

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.

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

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

Network (WiFi + Ethernet) Performance

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

WiFi Throughput in MB/s - Click to Enlarge

WiFi Throughput in MB/s – Click to Enlarge!

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

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

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

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

Storage performance

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

Click to Enlarge

Click to Enlarge

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

Gaming

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

Mecool BB2 Pro Benchmarks

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

Click to Enlarge

Click to Enlarge

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

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

Click to Enlarge

Click to Enlarge

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

Click to Enlarge

Click to Enlarge

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

Conclusion

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

PROS

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

CONS (and bugs)

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

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

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

December 24th, 2016 25 comments

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

First Boot, First Impressions and Setup.

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

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

Click to Enlarge

Click to Enlarge

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

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

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

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

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

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

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

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

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

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

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

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

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

Power Consumption and Temperature

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

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

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

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

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

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

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

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

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

Audio Codec in Video PCM 2.0 Output HDMI Pass-through
AC3 / Dolby Digital 5.1 OK Audio OK (DD 5.1), but wrong aspect ratio
E-AC-3 / Dolby Digital+ 5.1 OK OK (DD 5.1)
Dolby Digital+ 7.1 OK OK (Dolby D+ 7.1)
TrueHD 5.1 OK OK (TrueHD 5.1)
TrueHD 7.1 OK OK (TrueHD 7.1)

DTS HD Master OK OK (DTS-HD MSTR)
DTS HD High Resolution OK OK (DTS-HD HR)
DTS:X (not supported by Onkyo TX-NR636) OK DTS-HD MSTR

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

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

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

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

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

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

HDMIRecorder App

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

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

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

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

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

OpenWrt and NAS functions

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

You can control OpenWrt main functions in Android settings…

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

Eweat R9 Plus SAMBA Transfer

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

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

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

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

WiFi Performance

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

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

Miscellaneous Tests

Bluetooth

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

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

Storage

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

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

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

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

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

Gaming

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

Eweat R9 Plus Benchmarks

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

The device reached 36,076 points in Antutu 6.2 against 34,976 points for Zidoo X9S Antutu score.

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

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

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

Conclusion

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

PROS

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

CONS (and bugs):

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

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

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

Merry Christmas to all!
