Original commit message from CVS: * gst-libs/gst/rtp * gst-libs/gst/rtp/gstbasertpdepayload.c * gst-libs/gst/rtp/gstbasertpdepayload.h * gst-libs/gst/rtp/gstrtpbuffer.c * gst-libs/gst/rtp/gstrtpbuffer.h * gst-libs/gst/rtp/Makefile.am * gst-libs/gst/rtp/README Support libs for RTP. Basicaly this add a GstRTPBuffer (extended GstBuffer) and a Depayloader Base class that shall be used by payload specific depayloaders.

GstRTPBuffer:
|

|
||||
A GstBuffer subclass that can has extra RTP information such as timestamps and
