Wanjohi 06b844b961 feat(neswire): open the audio server
Captures a session's audio and hands it to the transport over a local socket.
Third component in, imported as a tree from `nestrilabs/neswire` on the same
terms as the previous two.

Wired to the workspace, `nesprotocol` by path. 4 tests pass.

`bin/hub-stub.rs` is a stand-in for the transport's listener, which is what lets
this be developed and tested without the rest of a box existing. It names the
transport by its old name, and is left for the rename commit along with the two
in the compositor.

neswire

A small custom PipeWire sink for cloud gaming audio capture.

Currently for debugging uses RTP to send Opus (with FEC enabled by default) over to target address.

Testing

Mono/Stereo

Launch gstreamer pipeline to receive audio as so (will save incoming RTP audio into test.mkv):

gst-launch-1.0 udpsrc port=12345 caps="application/x-rtp,media=audio,encoding-name=OPUS,clock-rate=48000,payload=111" ! rtpopusdepay2 ! opusdec ! matroskamux ! filesink location=test.mkv sync=false

Then run neswire like so for example:

cargo run --release --bin neswire -- --rtp-addr 127.0.0.1:12345

Surround

Launch gstreamer pipeline to receive audio as so (will save incoming RTP audio into test_multi.mkv):

gst-launch-1.0 udpsrc port=12345 caps='application/x-rtp,media=audio,encoding-name=MULTIOPUS,clock-rate=48000,payload=111,encoding-params=(string)8,num_streams=(string)5,coupled_streams=(string)3,channel_mapping=(string)"0,6,1,2,3,4,5,7"' ! rtpopusdepay2 ! opusdec ! matroskamux ! filesink location=test.mkv sync=false

Then run neswire like so for example:

cargo run --release --bin neswire -- --rtp-addr 127.0.0.1:12345 --channels 8

For both afterwards, set the neswire sink as audio output source in your system (or specify it as output in some app/game), then play some audio, stop gst pipeline and sink, listen to results after.
