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 SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Fedora Linux 40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION 2352749 1 noahadvs 2024-09-10 07:20:53 +0000 I actually have a patch to add GPU accelerated VP9 encoding to KPipeWire (the library Spectacle uses for recording), but the problem is I don't have any way to test it. If you're willing and able to test that the patch works, we could merge it. https://invent.kde.org/plasma/kpipewire/-/merge_requests/91 2353034 2 fjbaldon 2024-09-11 10:13:01 +0000 After using libva-intel-driver for days, I'm not sure now if the bug is caused by Spectacle solely. As I've noticed, even chromium now doesn't do vp9 decoding, so this might be a driver issue. 2475913 3 nate 2025-12-10 17:01:24 +0000 *** Bug 513166 has been marked as a duplicate of this bug. *** 173459 2024-09-08 21:43:46 +0000 2024-09-08 21:43:46 +0000 output from vainfo a1fcd67b.txt text/plain 2082 fjbaldon VHJ5aW5nIGRpc3BsYXk6IHdheWxhbmQKdmFpbmZvOiBWQS1BUEkgdmVyc2lvbjogMS4yMSAobGli dmEgMi4yMS4wKQp2YWluZm86IERyaXZlciB2ZXJzaW9uOiBJbnRlbCBpOTY1IGRyaXZlciBmb3Ig SW50ZWwoUikgS2FieSBMYWtlIC0gMi40LjAucHJlMSAoMi40LjAucHJlMSkKdmFpbmZvOiBTdXBw b3J0ZWQgcHJvZmlsZSBhbmQgZW50cnlwb2ludHMKICAgICAgVkFQcm9maWxlTVBFRzJTaW1wbGUg ICAgICAgICAgICA6CVZBRW50cnlwb2ludFZMRAogICAgICBWQVByb2ZpbGVNUEVHMlNpbXBsZSAg ICAgICAgICAgIDoJVkFFbnRyeXBvaW50RW5jU2xpY2UKICAgICAgVkFQcm9maWxlTVBFRzJNYWlu ICAgICAgICAgICAgICA6CVZBRW50cnlwb2ludFZMRAogICAgICBWQVByb2ZpbGVNUEVHMk1haW4g ICAgICAgICAgICAgIDoJVkFFbnRyeXBvaW50RW5jU2xpY2UKICAgICAgVkFQcm9maWxlSDI2NENv bnN0cmFpbmVkQmFzZWxpbmU6CVZBRW50cnlwb2ludFZMRAogICAgICBWQVByb2ZpbGVIMjY0Q29u c3RyYWluZWRCYXNlbGluZToJVkFFbnRyeXBvaW50RW5jU2xpY2UKICAgICAgVkFQcm9maWxlSDI2 NENvbnN0cmFpbmVkQmFzZWxpbmU6CVZBRW50cnlwb2ludEVuY1NsaWNlTFAKICAgICAgVkFQcm9m aWxlSDI2NE1haW4gICAgICAgICAgICAgICA6CVZBRW50cnlwb2ludFZMRAogICAgICBWQVByb2Zp bGVIMjY0TWFpbiAgICAgICAgICAgICAgIDoJVkFFbnRyeXBvaW50RW5jU2xpY2UKICAgICAgVkFQ cm9maWxlSDI2NE1haW4gICAgICAgICAgICAgICA6CVZBRW50cnlwb2ludEVuY1NsaWNlTFAKICAg ICAgVkFQcm9maWxlSDI2NEhpZ2ggICAgICAgICAgICAgICA6CVZBRW50cnlwb2ludFZMRAogICAg ICBWQVByb2ZpbGVIMjY0SGlnaCAgICAgICAgICAgICAgIDoJVkFFbnRyeXBvaW50RW5jU2xpY2UK ICAgICAgVkFQcm9maWxlSDI2NEhpZ2ggICAgICAgICAgICAgICA6CVZBRW50cnlwb2ludEVuY1Ns aWNlTFAKICAgICAgVkFQcm9maWxlSDI2NE11bHRpdmlld0hpZ2ggICAgICA6CVZBRW50cnlwb2lu dFZMRAogICAgICBWQVByb2ZpbGVIMjY0TXVsdGl2aWV3SGlnaCAgICAgIDoJVkFFbnRyeXBvaW50 RW5jU2xpY2UKICAgICAgVkFQcm9maWxlSDI2NFN0ZXJlb0hpZ2ggICAgICAgICA6CVZBRW50cnlw b2ludFZMRAogICAgICBWQVByb2ZpbGVIMjY0U3RlcmVvSGlnaCAgICAgICAgIDoJVkFFbnRyeXBv aW50RW5jU2xpY2UKICAgICAgVkFQcm9maWxlVkMxU2ltcGxlICAgICAgICAgICAgICA6CVZBRW50 cnlwb2ludFZMRAogICAgICBWQVByb2ZpbGVWQzFNYWluICAgICAgICAgICAgICAgIDoJVkFFbnRy eXBvaW50VkxECiAgICAgIFZBUHJvZmlsZVZDMUFkdmFuY2VkICAgICAgICAgICAgOglWQUVudHJ5 cG9pbnRWTEQKICAgICAgVkFQcm9maWxlTm9uZSAgICAgICAgICAgICAgICAgICA6CVZBRW50cnlw b2ludFZpZGVvUHJvYwogICAgICBWQVByb2ZpbGVKUEVHQmFzZWxpbmUgICAgICAgICAgIDoJVkFF bnRyeXBvaW50VkxECiAgICAgIFZBUHJvZmlsZUpQRUdCYXNlbGluZSAgICAgICAgICAgOglWQUVu dHJ5cG9pbnRFbmNQaWN0dXJlCiAgICAgIFZBUHJvZmlsZVZQOFZlcnNpb24wXzMgICAgICAgICAg OglWQUVudHJ5cG9pbnRWTEQKICAgICAgVkFQcm9maWxlVlA4VmVyc2lvbjBfMyAgICAgICAgICA6 CVZBRW50cnlwb2ludEVuY1NsaWNlCiAgICAgIFZBUHJvZmlsZUhFVkNNYWluICAgICAgICAgICAg ICAgOglWQUVudHJ5cG9pbnRWTEQKICAgICAgVkFQcm9maWxlSEVWQ01haW4gICAgICAgICAgICAg ICA6CVZBRW50cnlwb2ludEVuY1NsaWNlCiAgICAgIFZBUHJvZmlsZUhFVkNNYWluMTAgICAgICAg ICAgICAgOglWQUVudHJ5cG9pbnRWTEQKICAgICAgVkFQcm9maWxlSEVWQ01haW4xMCAgICAgICAg ICAgICA6CVZBRW50cnlwb2ludEVuY1NsaWNlCiAgICAgIFZBUHJvZmlsZVZQOVByb2ZpbGUwICAg ICAgICAgICAgOglWQUVudHJ5cG9pbnRWTEQKICAgICAgVkFQcm9maWxlVlA5UHJvZmlsZTAgICAg ICAgICAgICA6CVZBRW50cnlwb2ludEVuY1NsaWNlCiAgICAgIFZBUHJvZmlsZVZQOVByb2ZpbGUy ICAgICAgICAgICAgOglWQUVudHJ5cG9pbnRWTEQK
