[gst-devel] rtspsrc plugin: udpsrc Internal data flow error

[Eric Zhang]

Hi, gst-devel:

    Seems that you selected the wrong rtpdepay & decode elements -- this 
is the most common reason for "internal data flow error" as I know.

    rtspsrc will open 2 udpsrc to receive udp packets from rtsp server, 
one for RTP data transfer and another is for RTCP. Actually, rtspsrc 
also use an udpsink element to send RTCP feedbacks to rtsp server. Refer 
to RFC2326, RFC3550 for more details.
