[Live-devel] Streaming LPCM audio at 48K with vobStreamer

No, but it could easily be modified to do so.  Streaming PCM audio is 
easy; just use a "SimpleRTPSink" (instead of a "AC3AudioRTPSink"). 
See, for example our "testWAVAudioStreamer" demo application.

One thing to watch out for: PCM data streamed within RTP packets must 
be big-endian.  If, instead, your source PCM data is in little-endian 
order, then you will need to add a byte-swapping filter before 
streaming it.  (There is also an example of this in the 
"testWAVAudioStreamer" code.)
