1. I've seen it in the debug messages. gst-launch or someone else told me
that it has "created rtspsrc instance named "source"".
2. I wrote a simple launcher in C and added the call to
GST_DEBUG_BIN_TO_DOT_FILE
http://n4.nabble.com/file/n1594578/player.png player.png  I've uploaded it
to the Nabble, hope, the link will be attached to my message.
3. Here is the output of gst-launch -v:
$ gst-launch -v '--gst-debug=rtspsrc:5,GST_REGISTRY:0,*:2'
--gst-debug-no-color
--gst-plugin-path=/home/wl/AVIK/player/rtspsrc/src/.libs playbin2 \
uri=rtsp://192.168.24.21/1286_bbc_world_news_2009_06_04_22_00_000.mpg \
rtspsrc0::debug=true

Probably, something like a full path
(/GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstRTSPSrc:source/)
will do. Will try.
