PipeWire, a widely used open-source multimedia server for audio and video on Linux systems, has released version 1.6.3. Key updates include fixes for RAOP-related issues, improved compatibility, and better RTP timestamp alignment to ensure AirPlay audio functions correctly on more devices.
The update also restores broader MIDI1 handling. Most nodes now support MIDI1 without unnecessary conversions to and from UMP, improving performance in environments that rely on traditional MIDI workflows.
On top of that, PipeWire 1.6.3 also resolves a regression affecting sample rate changes and addresses a potential integer overflow in memory mapping. The modules layer includes fixes for RTP stream crashes due to concurrent event emission, improved handling of specially crafted native-protocol messages, and corrections for properties and parameter enumeration in filter-chain.
The SPA layer update addresses an out-of-bounds read in the mix matrix, enhances compiler compatibility, restricts plugin loading to configured search paths, and reduces unnecessary MIDI format conversions.
Additionally, the Bluetooth code includes backported fixes to prevent crashes. Plus, the JACK component now ensures the timebase callback is not called with zero frames and increases the notify queue to minimize missed notifications.
