*** This bug has been marked as a duplicate of bug 492844 *** The user asked for hardware decoding, not encoding, so it's not a duplicate. Unfortunately, this is not a problem that can be solved in Spectacle. Either you do not have the correct codecs/drivers installed for decoding on Intel or QtMultimedia's backend for playing videos (could be ffmpeg or gstreamer) doesn't support this. It is also possible that the problem is in QtMultimedia itself rather than being a problem specific to one of the backends. QtMultimedia is the library Spectacle uses for playing videos. Unfortunately I cannot verify where the issue could be because I do not have an Intel GPU. |
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.
