PipeWire from the start was designed around handling the needs of both audio and video streams on Linux. While PipeWire is already in use for screencasting/recording under Wayland and working with Flatpak'ed applications, recently much of PipeWire's focus has been on addressing the use-cases of JACK and PulseAudio on the sound side. Now that the audio support is in quite good shape, Red Hat engineers are back to focusing on improvements to the video support...
