The PipeWire project has released PipeWire 1.4.9 today as yet another maintenance update to the latest PipeWire 1.4 series of this popular open-source server for handling audio/video streams and hardware on Linux systems.
PipeWire 1.4.9 is a small bugfix release that addresses a regression in node unprepared, which would leave nodes running, improves ALSA recovery when “3 periods” is not supported, and removes RestrictNamespaces from the systemd files to allow libcamera to load sandboxed IPA modules.
This release also fixes the initial SDP session hash and session-id, fixes a potential NULL deref in the profiler, fixes the UMP event compare function, and fixes a regression in the adapter that would cause it to fail to start and resume correctly.
Among other changes, PipeWire 1.4.9 improves headroom for SOF cards by setting it to the minimal period size by default, backports a lot of libcamera patches, such as support for calorimetry and thread-safety fixes, adapts to newer libcamera changes, and adds support for handling fd allocation errors in Avahi.
PipeWire comes pre-installed with many popular GNU/Linux distributions, and it’s the default option for handling multimedia streams and hardware. It is also used by default for camera handling in the Mozilla Firefox web browser. You can download the PipeWire 1.4.9 release right now from the official GitLab page.
