RX 6000 not working with GStreamer H265 Flatpak about obs-gstreamer

[aleksasiriski]

Here's the output from GStreamer H265 using RX 6600 (on RX 580 default obs vaapi is a slideshow, but GStreamer H264 and H265 worked flawlessly, on RX 6600 default obs vaapi works, GStreamer H264 also works but H265 is a mess):

This may be caused by the driver/mesa version being used. Or maybe some extra options you have set for the encoder.

My settings for encoder

OBS flatpak currently uses Mesa 21.3.9, even though 22.1.7 is available as stable.

[aleksasiriski]

Installing mesa-git from flathub-beta and running OBS with FLATPAK_GL_DRIVERS=mesa-git flatpak run com.obsproject.Studio results in an error message "Your graphics card is not supported, check if you have drivers installed", same thing happens if I leave 22.1.7 installed but remove 21.3.9.

@aleksasiriski make sure whatever mesa you're running has patent-encoumbered codecs (such as H.265) enabled. AFAIK, Fedora does not enable these by default anymore.

I believe I need mesa 22.2+ for it to work on RX 6000 gpus, which isn't the currently stable version for flatpak. I haven't had any luck with mesa-git from flatpak, OBS says:

Starting the output failed. Please check the log for details.

Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date.

This will be fixed when flatpak updates the Mesa version to 22.2 (currently it's 22.1.7) and when OBS 29 comes out (since 28 is still using Platform 21.08, which has Mesa 21 and not 22)

This isn't an issue of obs-gstreamer then. Track the issue in the distro's issue trackers instead.
