Bug ID: 513166
Summary: Spectacle doesn't seem to use hardware decoding.
Classification: Applications
Product: Spectacle
Version First 6.5.3
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: [email protected]

Target Milestone: ---
SUMMARY
As far as I know, Spectacle supports VA-API, but when I record video, I see a
high CPU load and intel_gpu_top doesn't show any activity for hardware video
decoding.
When I use OBS Studio or GPU Screen Recorder, intel_gpu_top shows load on the
"Video" engine. I also tried changing the video formats, but it didn't change
anything.
OBSERVED RESULT
High CPU load, no activity on the "Video" engine in intel_gpu_top. Hardware
decoding does not appear to be working.
EXPECTED RESULT
Activity/load on the "Video" engine in intel_gpu_top, functioning hardware
decoding.
Here are the logs when launching Spectacle:
