Review | Probox2 AVA Realtek RTD1295DD Android TV Box

Probox2 AVA is an attempt at something a bit different in this world of very similar Android based TV Boxes. It does that by incorporating a dual firmware which runs (at the same time) Android 6.0 along with OpenWRT. The latter is a Linux based firmware that is common in routers. It gives the device not only router-like abilities, but also NAS and several different possible server roles. On top of that, AVA’s elongated body contains space for a 2.5 inch HDD or SSD for storage.

My thanks goes to the Wilson from Probox2, for sending me a new and intriguing review sample!

What do we get in the box?

 The Probox2 AVA, DC Power adapter, HDMI 2.0 cable, a short user manual, and a standard IR remote control.

Looks and design

Usage and User Interface

AVA includes the standard launcher included with all recent Probox2 boxes. It is quite straightforward but quite differs from the standard Android vanilla launcher

On top of these standard screens, we can find the HDMI-In app that provides us with the ability to use a HDMI source (such as a digital TV tuner, a camera with a mini/HDMI port, or any other live source) to display it using the AVA (either full-screen or in a window – PictureInPicture) and even record it – immediately or with the scheduling function. Here are some pics of this function:

The second big feature in the versatile AVA box is the OpenWRT firmware, which in reality turns this box into a hybrid Linux/Android machine. The OpenWRT firmware deserves much more reading to get what it can do, but the gist of it would be a cross between Linux based router and a multitude of servers – including VPN, Web server, File Server (NAS) and many more. Here is the basic system screen of the web interface for the OpenWRT function:Probox2,AVA,realtek,RTD1295DD,openwrt,NAS,router,server,linux,tv box,streamer,review,android,kodi,ultrahd,fullhd,internet,Home,screen,OpenWRT

Benchmarks and Testing

All benchmarks have been repeated 3 times and results have been averaged to give a more accurate reading:

Antutu Benchmark

Probox2,AVA,realtek,RTD1295DD,openwrt,NAS,router,server,linux,tv box,streamer,review,android,kodi,ultrahd,fullhd,internet,antutu,benchmarkThe Antutu benchmark tests single core performance over multi-core as it is a better indication of the performance of one device over others in most situations. Antutu synthetic tests place AVA about one third from the top of the chart. The score it gets spells good performance, even with the 10 other boxes that precedes it.

In the new version (Work 2.0) which is more task intensive and varied, AVA takes first place in the total average score. However, in the older version (Work 1.0), AVA takes only 5th place – behind four boxes based on Rockchip chipsets. Still, a very respectable result.

3D Mark Benchmark

Probox2,AVA,realtek,RTD1295DD,openwrt,NAS,router,server,linux,tv box,streamer,review,android,kodi,ultrahd,fullhd,internet,3dmark,benchmark3D Mark is a labor intensive 3D animation and gaming Benchmark. It runs a series of 3d heavy game and video animations. AVA takes 11th place in this test, which places it on the top third of the chart. It still means that AVA should be able to handle any 3d intensive task (AKA games) that will be thrown at it.

Video Playback testing (Using KODI/TV Center)

Resolution Video Format Local Playback Network (Wi-Fi/LAN) Playback
720p (1280*720) AVC (High@L4.1)  Playing correctly  Playing correctly
1080P (1920*1080) AVC (High@L4)  Playing correctly  Playing correctly
 2160P (3840*2160) HEVC (H.265) / 10Bit  Playing correctly **  Mixed Results
4K (4096*2304) AVC (High@L5.1)  Playing correctly  Mixed Results
4K TS HEVC files HEVC (H.265)  Playing correctly  Buffering and Stutter

Probox2 tried to employ an external player in AVA, but that was problematic when it comes to LAN shares (authentication issues – I suspect due to the inclusion of OpenWRT). So they used a workaround: When playing content off LAN, Kodi uses its own internal playback engine – which means reduced compatibility and buffering issues with heavy bandwidth/decoding files (such as 4K HEVC TS files). When playing content from a locally connected storage (I tested using a 32GB SD card), Kodi used their own proprietary external playback engine which is tailored for this hardware. That meant that performance was near flawless as can be seen from the table bellow:

Antutu video tester which runs through multiple video and audio content did froze at first, and only worked properly after a recent firmware update. As can be seen, there are two point of interest: one is that two items did not play at all – that is unusual since all the boxes I’ve tested (around 40 so far) managed to complete the test successfully enough with only a few partial support results. The two partial support results are nothing of note (refers to MP4 combinations of AAC audio with AVC and MPEG-4 videos), but the items that failed to play are these:Probox2,AVA,realtek,RTD1295DD,openwrt,NAS,router,server,linux,tv box,streamer,review,android,kodi,ultrahd,fullhd,antutu video,benchmark,unsupported

These days, the viability of Kodi add-ons is very unreliable due to recent crackdowns against many of their developers. However, I tested several video add-ons and the ones that are still alive (such as exodus for instance) have performed quite well – even in HD streaming.

Network performance

Network performance has been tested using Internet speed measuring app, in WiFi and in Wired (*) mode. My Internet connection is 500 Mbit Symmetric Fibre connection.

  • Wired works over Power-line adapters and those has been upgraded now to a AV1200 kit which gives a big bump to network performance.

Issues and Bugs

  1. PCMark 8 Work 2.0 cannot complete benchmark testing as it gets stuck in the middle of the video tests
  2. Antutu Video Tester 3.0 cannot complete benchmark testing as it gets stuck at 66% of the test
  3. Two failed items in Antutu Video tester 3.0 – unusual for any TV Box
  4. Kodi set to play content over LAN only via its internal player which does not utilize AVA’s abilities to its fullest

First two issues were resolved after a reporting to Probox2 and waiting for a firmware update which arrived.


Gaming performance

As usual, I test three games: Angry Birds 2Asphalt 8 Airborne, and Walking War Robots. No root solution is available, therefore I could not measure CPU or RAM usage.

Angry Birds 2, a popular 2d game. It run smoothly enough, with reasonable load times. (same bug as most boxes with a blue key screen that would not be pressed – but it’s a game issue)videostrong,mecool,ki pro,amlogic,s905d,tv box,streamer,review,android,kodi,ultrahd,fullhd,internet,hybrid,stb,digital tv,receiver,angry birds 2,splash screen,game

Asphalt 8 Airborne , intense 3d racing game. Game loaded up fine (load times a bit long), but in a heavy city environment with many moving objects the game was not completely smooth. Air mouse/game controller worked perfectly (as it should as it’s the Remote+ by Probox2 themselves)himedia,a5,streamer,review,android,kodi,amlogic,s912,asphalt 8,airborne,game

Walking War Robots – an online 3d robot battle game. Game loaded fine and fast, even with the multiplayer/network features and multiple objects, the game run smoothly and even allowed (since a late update) to shoot and exit the game properly.mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,war robots,game,gamebench

Probox2 AVA Conclusions

Probox2 provided me with another quality product, and this time the AVA is a more sophisticated one. Offering good performance across the board, with a few gripes (4k heavy files are not played correctly over local network without using Kodi internal player) which most have been addressed.  I can truly recommend it – even with the somewhat high price tag.

Did I like it? Yes

Would I recommend it? Most definitely. Aside for the more standard bells and whistles (2.5″ HDD drawer, HDMI-in, and multiple format support), the OpenWRT firmware extends the abilities of the AVA to places that TV Boxes don’t usually venture to (NAS, VPN, Router functions and so on)
