Hi!

I'm a little bit new at Kodi (especially on Android more specially on Chromecast with Google TV) although I used 'XBMC' some years ago on Intel desktop. Sorry if my question was answered before but I simply can not find it.

Some days ago I installed Kodi onto my GCGTV just to check what are the limits of the construction.

1. I got the following audio passthrough to my Pioneer receiver: DD; DD+; DTS; multichannel PCM (for me it's nice as I could not passthrough high-def LPCM for music listening but could see movies for with me almost fine possibilities as my receiver could not handle Dolby TrueHD yet)
2. DTS-HD; DTS-X is one another thing as seemed I just got plain DTS passthrough instead those 'wider' ones (as if somebody also already wrote this)
3. 1080p 8bit h264 decoding was fine (from .MKV or .MP4 containers)
4. 1080p 8bit h265 decoding also was fine
5. 4k 8bit h265 decoding also was fine
6. But 4k 10bit h265 decoding was 'broken' (very slow rendering (1-2 frame per sec or slower) with lot more banding than I got with 8bit streams and also lot more than I got with alternate method (below))

Practically this is not problem for me now as my TV is one old Samsung - 55D7000 without any HDR possibilities, but interestingly if I cast with BubbleUPnP to this GCGTV seems it works. When I cast it with BubbleUPnP GCGTV seems can handle the stream. At this point I don't care about the quality or of any other aspect of the result, the only interesting thing that in this case GCGTV can handle the stream with full framerate. With Kodi directly on the GCGTV the result is a very slow, and overloaded result.

Could anybody help me, what I do wrong?

Thanks for your efforts in advance!

Yeah 4k HEVC content run like utter crap in Kodi on the Chromecast from my experience. The only solution I found to stop Kodi from stuttering upon playback was to disable "Allow hardware acceleration - MediaCodec (Surface)" in the player settings. This made 4K videos watchable but their framerate isn't the best. Disabling this option also has adverse effects, for instance, a 480P episode was unwatchable with this setting disabled.

Thanks for your confirmation, in case my result is not my fault. But over on it from my aspect it has a little bit more resolution about the problem as for me 4k HEVC not mandatory unwatchable. 8 bit 4k HEVC plays fine, but 10 bit is 'more' then stuttering. 10 bit is simply eat my GCGTV. I test it again some minutes ago and at the end I had needed to pull the power out as from it's menu I simply could not reach the restart or any other quick possibility to kill Kodi because Kodi's system overload.

But from another aspect the same 10 bit 4k HEVC plays fine on the same GCGTV if I cast from my Android phone through BubbleUPnP DLNA controller/streamer/whatever... When I cast with that the video decompression also made by the GCGTV itself as BubbleUPnP does not transcode (if I want it). So there is way when GCGTV can handle the same stream I think the mentioned stuttering result should be the problem of Kodi and not the hardware (or my false configuration).

What's your opinion?
