[pulseaudio-discuss] Listening to the RTP stream

[Jan-Benedict Glaw]

Hi!

I played with the RTP sending module a bit. Seems to work, at least
there's a RTP stream coming out of the box :)

However, are there alternative ways to listen to this/these streams
except using the receiver module? Eg. in theory, mplayer should be
able to listen to this stream, but it seems to have problems
recognizing the contents. How do I actually tell it to use a specific
PCM format?

Looks like this:
