raudraido 43 Posted August 25, 2019 Share Posted August 25, 2019 Hi, I do not understand why My radeon rx560 won't decode, instead Emby switch to software..? >>>>>> FindVideoDecoder - MediaType: hevc, Mode: Custom Info FindVideoDecoder - Checking: 'DX11VA Radeon RX 560 Series - H.265 (HEVC)' (Priority: 100) NoMatch Codec does not support profile 'Main 10 Profile' ffmpeg-transcode-05b7eab5-db4c-4b87-b0f2-20b20cf83b71_1.txt Link to comment Share on other sites More sharing options...
Luke 37010 Posted August 25, 2019 Share Posted August 25, 2019 Does it support 10 bit hevc? Link to comment Share on other sites More sharing options...

Luke 37010 Posted August 25, 2019 Share Posted August 25, 2019 it appears that it does not. Have you followed our hardware acceleration setup guide? https://github.com/MediaBrowser/Wiki/wiki/Hardware-Acceleration-Overview Link to comment Share on other sites More sharing options...
Q-Droid 634 Posted August 26, 2019 Share Posted August 26, 2019 The card itself is capable of decoding 10-bit HEVC but the software and drivers have to be able to leverage the features. Link to comment Share on other sites More sharing options...

Q-Droid 634 Posted August 27, 2019 Share Posted August 27, 2019 Can you explain more detail? Which card/soft/drivers combo can hardware decode 10bit HEVC? GTX1660? What I wrote is specific to the rx500 series. The decoder on that card, UVD 6.3, supports 10-bit hevc. For it to work with Emby the ffmpeg api has to be able to use the features. Also the drivers have to be right for all of them to work together. Nvidia cards use different apis. Link to comment Share on other sites More sharing options...
softworkz 3326 Posted August 30, 2019 Share Posted August 30, 2019 (edited) @@raudraido - AMD has been very late to the game of hardware video acceleration. Nvidia has been assisting to get support for their hw acceleration into ffmpeg in earlier days. Intel is still actively contributing to ffmpeg, enabling all their latest encoding features for use with ffmpeg. Now, guess what AMD is doing? (nothing) AMD is offering their AMF SDK and this will allow you to do 10bit HEVC decoding. But decoding via AMF is currently not implemented in ffmpeg. Only encoding is implemented and Emby can make use of that. For decoding, there's only DXVA, which is a Microsoft interface, supported by ffmpeg and Emby can make use of that. But the supported codecs and for each codec which resolutions, profiles, levels and color formats are supported: That depends on the Windows graphic driver. You can try the Microsoft driver and the specific latest AMD driver for your Radeon. If you don't get 10bit HEVC decoding in both cases, please contact AMD for further support.

Thank you for clarification. As I understand I have DXVA and Radeon latest drivers enabled, still I do not get hardware decode on 10bit HEVC. So i'll need to figure it out with AMD.

Next gen (starting from Kaby Lake) already supports HEVC 10bit decode/encode as well. Link to comment Share on other sites More sharing options...
raudraido 43 Posted August 30, 2019 Author Share Posted August 30, 2019 (edited) Which choice is better, purely from Emby perspective, change CPU to Kabylake which supports HEVC10bit or change gpu to nvidia 1660ti?

softworkz 3326 Posted August 30, 2019 Share Posted August 30, 2019 One thing to know is that in both cases, the video acceleration is done by dedicated units in the hardware, so you cannot look at the 3D performance to compare. Both are good choices (and better than AMD). Link to comment Share on other sites More sharing options...

One thing to know is that in both cases, the video acceleration is done by dedicated units in the hardware, so you cannot look at the 3D performance to compare. Both are good choices (and better than AMD). One thing to keep in mind is that there is a limit of 2 streams (I believe) when using the Nvidia consumer cards to decode. The Intel chip won't have that limitation. ETA: You may be able to get around the Nvidia limitation, but it will involve flashing a different firmware I believe.

It's a bit awkward that we let users find out by trial and error what capabilities are supported by their hardware. Or even worse: Let users post their hw logs and we need to look through them to tell the user about his hardware's capabilities...

softworkz 3326 Posted August 30, 2019 Share Posted August 30, 2019 (edited) Sorry, I wasn't paying attention. DX11VA DXVA2 and D3D11VA (= DX11VA) are the same, right? I noticed the details in the posted image above after my post and your response. It's two different APIs for the side of the application that wants to use it but in both cases you're accessing the same set of decoders implemented by the graphics driver. The most important difference is that DXVA2 is based on DirectX 9 and requires an active desktop session having video memory allocated (= requires a monitor to be connected). D3D11VA does not have this restriction (= works on headless machines) but it can be a little bit slower. That's the reason why we're having both in Emby.

I wrote DX11VA because it is listed in the HEVC decoder list image posted by raudraido. I wasn't sure if that was the Emby UI side equivalent of D3D11VA but this is over my head so I'll leave it be.

softworkz 3326 Posted August 30, 2019 Share Posted August 30, 2019 DXVA2 is an official name, but there is none for the DirectX 11 variant. So DXVA2 is one side and everything with 11 is the other side. Sorry for the confusion. Link to comment Share on other sites More sharing options...
