Looks like a solid list, thanks . Should be comparable to FTV Stick 4K afterwards.

Quote:So - on my list:
- Implement YUV 10 bit scanout
- Implement HBR bitstream audio support (8 channel IEC)
- Expose the proper refreshrates via the API YOU (google) invented
- Implement what the chip supports (Dolby-Vision, HQ scaling, etc.)

For most platforms I expect AV1 will be supported alongside, rather than replace, h.265 for UHD HDR content - as so many existing hardware players (Smart TVs, Fire TVs, Apple TV 4K, Roku etc.) used for Netflix, Prime, Disney+ etc. 'in the field' won't support AV1 yet, and it won't be an issue for UHD BD Rips, BD Rips or DVD Rips unless they are re-encoded in AV1 I guess.

Looks like Android Smartphones already have limited Android Netflix App - AV1 support via the open source dav1d decoder.
Netflix is using AV1 to save on Mobile streaming data usage., see the netflixtechblog (click)
Quote:I know Kodi v19 Matrix (click), CoreELEC, possibly LibreELEC too has libdav1d (SW decode) support.

I don't see it being an issue either for 4K video playback. If 8K ever becomes popular then AV1 might gain some decent traction.
Google is not about to abandon their free to use VP9 codec.

Of course you wouldn't be able to use any Android apps but you could run Kodi with the Composite addon for any Plex content.
I've been thinking of getting a Nvidia Shield 2019 - or a CCWGTV to play my ripped content through either Plex or Kodi - 4K HDR content.
I really prefer the simplier CCWGTV solution - do you reckon it'll work or am I better off just getting the Shield anyway?

There's no reason so many Android boxes with perfectly fine hardware as well as full certification for Netflix etc, do not allow lossless audio just due to this.

I think it's more a case that they haven't bothered to, not that they can't. I suspect that not enough people in the Google team/chain whatever behind this product 'get' the need for dynamic refresh rate switching. The previous Chromecasts didn't support it either. Did the original Nexus Android TV player?
Given that Netflix don't seem to care unduly either (the only platform they seem to support frame rate switching on is the Apple TV tvOS platform) - I guess it's no surprise...

I tried a couple of THX trailers that aren't HDR and they worked just fine. Although if they are longer the buffering might have come up like in the Dubai clip. The bit rate is highest in the Dubai clip so that might be part of it as well. The other two are HDR10 clips that won't play at all. This is mirrored in other files I have tried that work well if they are not HDR10.(2020-10-09, 22:39)flips22 Wrote: I'm struggling with 4k video on my setup. Almost all of the files I've tried aren't working at all, displaying a frame a second or so. I tested some 4k demo files and I'm getting the same results. I thought I would share and see if it is just me, or if it's just a hardware limitation. Initially I thought it was network bandwidth, but switching to ethernet didn't improve anything.
I tested 3 4k demos, the AVC file (Dubai) played the best, but I still got a buffering circle every 20-30 seconds or so. The other two HEVC files barely played at all. With my other files I played around with audio streams thinking it might be an audio issue, but I didn't have any luck there either.
I should also mention that my TV is 1080p, not sure if that is having an effect or not.
Looks like both of your 4K samples are in HDR. Can you try an SDR 4K file?

On these AMLogic based boxes, you only get a single resolution and refresh rate in the white list. Naturally, Kodi will not be able to switch to different ones because it only knew there is one resolution and refresh rate that is supported by the device.Kodi for Android switches refresh rates just fine on AMLogic boxes, and shows multiple resolutions. You can't use such a blanket statement, maybe this Google device won't do it but my Ugoos S905X2 certainly does.
