SUMMARY The MP4/H.264 option in spectacle doesn't work properly. I've attached a example video. STEPS TO REPRODUCE 1. Set Spectacle to record in MP4/H.264 2. Record OBSERVED RESULT Video comes out as garbled EXPECTED RESULT Video should be normal SOFTWARE/OS VERSIONS Linux: Arch Linux KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2

Setting AMD_DEBUG=noefc removes the garbling. The video isn't perfect, but at least it's watchable.
Can reproduce this. I;'m using AMD CPU+GPU, might be hardware specific? I can provide more info for debugging if instructed.
I have the same issue. Arch Linux with these versions: lib32-libva-mesa-driver 1:24.0.6-2 lib32-mesa 1:24.0.6-2 lib32-vulkan-radeon 1:24.0.6-2 libva-mesa-driver 1:24.0.6-2 mesa 1:24.0.6-2 mesa-utils 9.0.0-4 vulkan-radeon 1:24.0.6-2 CPU: Ryzen 7950X3D GPU: Radeon 6900XT Logs say it's using the GPU to record. Last I checked (>1 year), I'm able to record H.264 / H.265 without issue using either the iGPU or dGPU via OBS. I know for sure H.264 / H.265 on the iGPU work currently with OBS, since it's what I use for normal recording. Recording using vp9 also works fine. The only difference in the logs are these lines: [h264_vaapi @ 0x7dd9c80b3680] Driver does not support some wanted packed headers (wanted 0xd, found 0x1). which it says once when the recording starts, and EE ../mesa-24.0.6/src/gallium/drivers/radeonsi/radeon_vcn_enc_1_2.c:1224 radeon_enc_encode_params UVD - DCC surfaces not supported. which it spams until the recording stops.
Similar issue happening on Intel, but rather than producing a completely garbled video Spectacle instead creates a weird artifact right at the bottom. Screencast example: https://youtu.be/SbxUWhWl9Ek GPU: Intel HD Graphics 5500 Distribution: Arch Linux Package versions: spectacle 24.08.3-1 kwin 6.2.3-1 libva 2.22.0-1 libva-intel-driver 2.4.1-3 libva-mesa-driver 1:24.2.6-1 libva-utils 2.22.0-1 mesa 1:24.2.6-1 mesa-utils 9.0.0-5
https://docs.mesa3d.org/envvars.html says this environment variable "Disable[s] hardware based encoder color format conversion". Xaver, could this be a driver bug? Antti, what GPU are you using? Also is it still reproducible today with the version of Spectacle shipped in Plasma 6.3? Eli, that's probably a different issue; please open a new bug report for it. Thanks?
This was worked around in kpipewire for Plasma 6.1, not sure how it would still happen in 6.2+: https://invent.kde.org/plasma/kpipewire/-/merge_requests/135
AMD Radeon RX 5700. This seems to be fixed when I tried this on spectacle 6.3.2. Setting file format to MP4/H.264 produces normal videos.
The original report was from 6.0.1, so it seems like it's fixed.
