Hardware Video Encoding is not detected on OBS Studio

It has been a long time since I haven’t seen seen hardware acceleration for video encoding on OBS studio, Chromium browsers or Firefox. Is this a common problem for AMD GPUs or just mine?

Is obs-studio-freeworld installed?

There is no obs-studio-freeworld, just obs-studio

The fedora obs-studio package can’t include h264 support, you need obs-studio-freeworld from rpmfusion repo to add h264 support.

But the issue was the same as the one provided on Arch. My workaround was to choose Advanced menu on the Output section and choose a proper encoder. But what about browsers? Also, how can I install freeworld version? I couldn’t find it from dnf

You need the mesa-*-freeworld packages

$ rpm -qa mesa* |grep freeworld
mesa-vulkan-drivers-freeworld-25.0.4-1.fc42.x86_64
mesa-vdpau-drivers-freeworld-25.0.4-1.fc42.x86_64

I was able to use HW acceleration on OBS, but audio encoder doesn’t look to work well. There is always cracking/popping sounds on pause/play. The issue is on others programs, except Telegram, audio recording works well here. Is it because of audio encoders?
