Bug ID: 492844
Summary: VP9 encoding not working
Classification: Applications
Product: Spectacle
Version: 24.08.0
Platform: Fedora RPMs

output from vainfo
SUMMARY
Attached is an output from vainfo. I'm having high cpu usage when I do webm/vp9
screen recording on spectacle. The default format is webm/vp9 and when I switch
to mp4/h.264, cpu usage drastically decreases. I'm also seeing activity on the
Video row when I'm using mp4/h.264 but nothing on webm/vp9. I have this line on
my vainfo output so I assume I can encode vp9 on my igpu:
"VAProfileVP9Profile0: VAEntrypointEncSlice"
STEPS TO REPRODUCE
1. Screen record using Spectacle (Wayland)
2. Use System Monitor or intel_gpu_top to monitor cpu and gpu usage
3. Spectacle does not offload its encoding to the gpu, instead it uses only the
cpu
OBSERVED RESULT
Spectacle does not use the gpu when encoding the video
EXPECTED RESULT
Spectacle uses the gpu when encoding the video
