Upstream mesa removal of AVC/HEVC/VC-1 hardware acceleration (AMD GPUs)

Non-technical Questions

I checked VAAPI:

$ vainfo
Trying display: wayland
vainfo: VA-API version: 1.16 (libva 2.16.0)
vainfo: Driver version: Mesa Gallium driver 22.2.4 for AMD Radeon RX 5700 (navi10, LLVM 14.0.6, DRM 3.48, 6.0.11-1-MANJARO)
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileJPEGBaseline           : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD
      VAProfileVP9Profile2            : VAEntrypointVLD
      VAProfileNone                   : VAEntrypointVideoProc

It shows no H264 and no H265 support.

Video decoding

I checked mpv media player and twitch video stream on Firefox, they use ffmpeg, H.264 video decoding worked fine with AMD GPU hardware acceleration, CPU total usage is lower than 10% like before, nothing difference.

Video encoding

But I tried to test video encoding benchmark using ffmpeg with VAAPI

ffmpeg -hwaccel vaapi -i <YOUR_VIDEO_FILE.mp4> -f null - -benchmark

AMD CPU total usage is higher than 60%. It seem video encoding is affected when using AMD GPU and mesa. Intel iCPU has no issue.
