Hmm. Good question. This used to work out of the box. We use the
standard type descriptors for S16BE uncompressed audio. Nothing
special, very basic stuff.
According to the output you pasted mplayer ignores the RTP data type
codes now and instead tries to recognize the data time with
"magic". Which is a bad idea I would say. It should simply trust the
type descriptor we use in those packets.
Could you please ping the mplayer people about this? Seems to be a
parsing issue on their side.
Another client for RTP that works fine is "dumprtp" from the dvbstream
package. And I heard some people had success with VLC.
