how to output rtp stream from a wav file by gstreamer pipeline

[Emile Semmes]

If your wav file is basically uncompressed audio (LPCM), if you take the 
src pad from wavparse, you can payload it as L16 audio. For example:

filesrc ! wavparse ! rtpL16pay ! udpsink

You'll have to play with that pipeline a bit, but it should be enough to 
get you started. Especially since you're streaming from a file, you'll 
need to make sure you throttle it so the file seems like a live source 
and it doesn't send it as fast as possible.

Also, VLC probably won't know the stream unless you provide it an .sdp 
file with the media and payload defined in it.

HTH,
Emile
