The PipeWire project released today PipeWire 1.4.2 as a minor update to the latest PipeWire 1.4 series for this popular open-source server for handling audio/video streams and hardware on Linux systems.

Highlights of PipeWire 1.4.2 include extra checks for MIDI to avoid 100% CPU usage on older kernels, support for using header metadata by default in the videoadapter, improved pw-cat verbose sndfile format debug, improved handling of set_format results from v4l2, and the addition of the missing –channel-map long option for pw-loopback.
