	The current architecture uses the following processing: - capture raw audio from PipeWire as unsigned 16 bit integers - convert with a `ffmpeg` process to OGG / FLAC - stream the `ffmpeg` output to multiple soundboxes via TCP Only the first part is different for URL sources. Since using PipeWire significant latency (up to 15 seconds) were measured. It turned out that this happens exactly when zero bytes (silence) are fed into the `ffmpeg` process. This commit avoids this by dropping those empty samples. It has to be made sure that only samples are dropped where both channels are zero. Otherwise audible noise is the result.
2024-12-08	pipewire: Add experimental PipeWire support	xegineering
	This implements a PipeWire capture device which can be used as an input source instead of the already available URL input. Known issues with the current PipeWire support are: - user has to connect the monitor of the default audio sink to the capture device manually - correct shutdown has to be tested - multiple instances do not work - medium code quality requires refactoring Since this is nevertheless usable and possible unknown bugs should be figured out in practise soon this implementation is already added. Bugfixes and refactoring might follow.
