gstrtspsrc question

[Muzzu Daniela]

To use a more specific pipeline you can try something like:

gst-launch-0.10 rtspsrc location="rtsp://your_url_here:port/path" name=d
  d. ! decodebin2 ! autovideosink
  d. ! decodebin2 ! autoaudiosink

In your C++ app, you will have to connect to the "pad-added" signal of your rtspsrc source, then dinamically link the source and decoder pads in the related callback. The callback will be invoked twice, once for video and once for audio: you can discover which kind of media type is by looking at the pad's caps.

Try with something like:

gst-launch-0.10 playbin2 uri=rtsp://your_url_here:port/path

with enough debug trace (--gst-debug-level=3 or 4?) to see what playbin2 does (beware: I read in the changelog that playbin2 dropped the "2" and became playbin in gstreamer-1.0).
Or you can see a graph of the same pipeline setting GST_DEBUG_DUMP_DOT_DIR and then looking at the dot files (see http://gstreamer.freedesktop.org/wiki/DumpingPipelineGraphs for details).

On this site (http://hughesbennett.co.uk/Graphviz) you can even paste the content of your dot files and see the graphs in the browser without installing anything.

Strictly talking about your question have a look at gstrtpbin:

http://www.freedesktop.org/software/gstreamer-sdk/data/docs/latest/gst-plugins-good-plugins-0.10/gst-plugins-good-plugins-gstrtpbin.html

and at the examples here:
