AMD HEVC Main10 Profile

AMD HEVC encoder is missing the Main10 profile which is for 10 bit but for some reason (complicated and convoluted but it's on the internet) Main10 is more efficient, even for 8 bit, when encoding.

This is what I get, I'm using Jellyfin FFmpeg 6.0.1-1 (but I think it's on 6.0 as well):

It seems your AMF is outdated.
https://github.com/Vouk/voukoder-ffmpeg

I don't know why but it doesn't have some of the options normal FFmpeg has had for at least a year.

The place your FFmpeg (https://github.com/Vouk/voukoder-ffmpeg) gets AMF from (https://github.com/GPUOpen-LibrariesAndSDKs/AMF) says "Version 1.4.21: AMD Radeon Software Adrenalin Edition 21.10.1 (21.30.25.01) or newer. Added PSNR/SSIM score feedback, new QVBR rate control mode and LTR mode for encoders, added HDR support for HEVC encoder and color converter, new EncoderLatency sample app."

Your FFmpeg says that it is on the latest version of AMF but it clearly isn't. I downloaded your FFmpeg and it was clearly out of date. That's part of the problem.

They added Main10 on December 3rd, 2021. I'm looking through your FFmpeg Github workflows and if I can figure it out I'll make a PR.

It's strange, the static build I downloaded from https://github.com/Vouk/voukoder-ffmpeg/releases has ffmpeg-win64-static-release\include\AMF\ and all the files match the GitHub master branch https://github.com/GPUOpen-LibrariesAndSDKs/AMF but the FFmpeg still shows no main10 and errors out when attempting -profile main10 even though the exact same command in Jellyfin FFmpeg works. I think the FFmpeg build is somehow using an older version of AMF even though ffmpeg-win64-static-release\include\AMF\ has the latest files.

The only thing to add is that your latest build of FFmpeg and the latest version of Voukoder remain with an outdated version of AMF.
