PipeWire is a server and user space API to deal with multimedia pipelines.

Some of its features include:

* Capture and playback of audio and video with minimal latency;
* Real-time Multimedia processing on audio and video;
* Multiprocess architecture to let applications share multimedia content;
* GStreamer plugins for easy use and integration in current applications;
* Sandboxed applications support.

NOTE: This is built for both x86_64 and i586 because aac codec is disabled in official repository, which is pretty useful in general.
