thinking about getting this unit only using it for Kodi and Youtube(via web) with my 4K tv
1. Can i plug and power the unit through the powered USB port on my tv so that when tv turns off the unit turns off as well? Is this safe to do with this unit?
2. Was going to purchase with 8GB eMMC Black Module C2 Linux dont mind the extra boot time everytime tv/C2 starts?
3. Can i put games on it a use it as a gaming system if i buy controllers?
4. Which is better Android or Linux eMMC for what im trying to do?

Hi, what type of deinterlacing is available on c2 for live tv HD and SD broadcasting when running LE?
In terms of quality, how does it compare to Rpi2&3 deinterlacing (MMAL Advanced) and Intel Braswell VAAPI-MCDI?
How would you rank them?
Edit: and what about scaling? Intel is great with Lanczos3 Optimized, Rpi is quite good (not as Intel).
Thanks

Deinterlacing on the S8xx/S9xx AMLogic devices use Motion Adaptive, Edge Enhancing, Hardware deinterlacing from the VPU for mpeg2 and H264. With the S9xx, It's indestnguishable from that of my new 4K TV, the quality is that good, it's really excellent for fast action sports viewing.
If you want to, you can also configure LE 7.x.x on the C2 to use high quality, full motion YADIFx2 Software Deinterlacing for 480/576i mpeg2 content. This is what the RPi uses. mpeg2 interlaced DVD's will use YADIFx2 automatically.
Scaling is done in Hardware I believe via the VPU again. I rarely see it because if you use full automatic Refresh Switching in LE, then 720, 1080 and 2160p will be output at those resolutions and you can then use a (4K) TV's superior scaling anyway. I leave the GUI in 1080p for viewing 576i, 720p and 1080i TV content.
It's all seamless and I've honestly seen no complaints.
BTW: Interlaced 29.97fps VC-1 BluRay is now fixed when using the latest C2 LE version when I last tested.

Question about 3D: as far as i have seen, the C2 decodes MVC full frame 3D and sends it to the TV as TAB (over/under) instead as full frame like the RPi.
Isn't it possible on 4k TVs to send it in 2160p to get the full resolution?
Regarding 3D: i havn't found yet a setting that will play imidiatly the 3D files with right picture aspect. If i start a MVC-MKV, the TV switches in 3D mode, it will be shown as TAB. I had to go to the onscreen menu and choose "same as movie" and than it will be played fine. On generell setting i have choosen "same as movie" but also over/under doesn't work.

I have a Zotac ND22 in the bedroom running LibreELEC and a RPi2 with OSMC in the living room sharing the contents of an attached 5TB USB drive. Using SMB, the RPi2 streams even my highest bit rate 1080p content quite well to the ND22 in the bedroom via two DLink 701AV powerline adapters. Knowing that the ethernet jack of the RPi2 was only 10/100, however, while everything else in the chain was gigabit I figured that using the 10/100/1000-equipped C2 (with wrxtasy's latest 7.1.0 release) should stream HD media equally as well and, certainly, even marginally faster since the RPi2 would be acting as the network bottleneck if there was one. Much to my surprise, after running a few tests it became quite evident that the technically superior C2 was only serving media HALF as fast (if that) than the otherwise inferior RPi2.
Am I missing settings somewhere that, by default, is crippling the C2's SMB performance?
