I have to create a service which captures the audio from the PC microphone and to broadcast it as UDP packets. I am on a Debian platform and I have to use Python (3.7).
I would like to use PyAV because I have to link this broadcasting system to a local custom WebRTC service using aiortc, which relies on PyAV.
I have to do this because I cannot access the same audio source (ALSA) from several processes (RTC peers), so I was thinking to create a UDP broacasting system in a localhost environment. Is this the best practice? Have you any other idea?
I have noticed here that with the call: av.open("udp://xxx:nnn", format="alsa") I should be able to receive audio UDP packets, but I am not sure how to generate a UDP server which captures from the mic and sends the UDP packets, so, how to create the server side of this implementation? In particular, I managed to capture the audio with: av.open("hw:0", format="alsa"), how can I send the captured buffer over UDP sockets?
