Open antonpetrovmain opened 1 month ago

antonpetrovmain commented 1 month ago

Windows build number:

10.0.19045.0

Your Distribution version:

2024.2

Your WSL versions:

PS C:\Users\anton.petrov> wsl --version WSL version: 2.2.4.0 Kernel version: 5.15.153.1-2 WSLg version: 1.0.61 MSRDC version: 1.2.5326 Direct3D version: 1.611.1-81528511 DXCore version: 10.0.26091.1-240325-1447.ge-release Windows version: 10.0.19045.4529

Steps to reproduce:

  1. sudo sunshine
  2. Observe an error using hardware encoding: 
    [2024:07:26:07:01:20]: Error: [h264_vaapi @ 0x5653259a0400] No usable encoding entrypoint found for profile VAProfileH264High (7).

WSL logs:

No response

WSL dumps:

No response

Expected behavior:

Hardware encoding should work for sunshine server.

Actual behavior:

Sunshine falls back to software encoding: [2024:07:26:07:01:21]: Info: Found H.264 encoder: libx264 [software]

Does that mean the current d3d12 drivers do not support hardware encoding using H264? I see only decoding capabilities: VAEntrypointVLD and I do not see the ones for encoding: VAEntrypointEncSlice

antonpetrovmain commented 1 month ago

Or does the hardware not support H264 encoding? Maybe this is the case, if I read this article correctly: https://www.intel.com/content/www/us/en/developer/articles/technical/linuxmedia-vaapi.html

Can somebody more knowledgeable please confirm? :)
