AMD GPU Transcoding support?

[EniGmA1987 1]

I see a lot of people asking about Nvidia support and Quicksync, but does Emby support AMD's VCE for accelerating transcoding of media files? I am going to be putting a server together when this tax refund comes through and would like to be able to get a GPU that could support 6-8 streams of 1080p and a stream or two of 4k as I am upgrading one of my projectors to 4k soon. Nvidia drivers dont allow more than 2 streams, so it is between AMD and Intel QuickSync. Id prefer to build a server with a Ryzen+ processor when they come out in a couple months, which obviously wont have QuickSync capability. So would I be able to use an RX480 I have laying around for GPU acceleration? Or is there no support for AMD cards at all?

 

Or if there is no support for AMD graphics cards, does anyone estimate that an 8 core/16 thread 4GHz processor may be able to do that many streams on the CPU?

Not at this time but it's possible for the future. We use ffmpeg so it all depends on what that supports. Thanks !

I'm in a similar situation today and am wondering if the Emby hardware transcoding support situation for discrete AMD GPUs has changed in the last year?

 

Has anyone had any luck with VAAPI or VCE hardware transcoding with a Radeon 5xx series card? Are there any steam limitations like with consumer nvidia cards?

Hi, yes it has changed. Support is quite a bit better now:

Thanks Luke, I came across this wiki page and the fact that the Linux Radeon drivers are listed also makes me think this will work.

If anyone has any experience using this with any RX 4xx or 5xx series GPUs, I'd be curious about steam limitations.

Very difficult to judge stream limitations because it depends on the original files codec and bitrate, the target bitrate, etc.

 

All I can say is I use a RX570 and I've seen stuff like transcoding at 140fps...

 

And HEVC 10bit decoding doesn't work. Probably will with the new Navi cards.

Of course, I was referring to any strict limitations (e.g., NVidia cards having a two stream limit, no matter the size of the workload). I haven't heard of any such limits on AMD GPUs, wanted to confirm is all.

There are no hard limits.

Has this situation with the most recent updates to both Emby and ffmpeg ?

Hi, yes amd is supported.
