Bug ID: 497206
Summary: Screen recording with KPipeWire fails when FFMpeg
isn't built against libvpx
Classification: Frameworks and Libraries
Product: KPipeWire
Version: unspecified
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
Screen recording with KPipeWire fails when using an FFMpeg build that is not
built against libvpx. I am using Spectacle as a reproducer.
STEPS TO REPRODUCE
1. I'm running Gentoo, so it was super easy to disable FFMpeg's libvpx support
and rebuild it. Other distros it's going to be more complicated.
2. Run spectacle from the command line for logging purposes.
3. Try to make a screen recording.
OBSERVED RESULT
Errors are output:
kpipewire_record_logging: libvpx codec not found
kpipewire_record_logging: No encoder could be created
Spectacle then freezes.
EXPECTED RESULT
FFMpeg's libvpx support should be specified as a dependency upstream so that
packagers know to declare it.
