HI, In streaming servers like Darwin,if we configure the port for streaming in server as "port:80",the streaming transport protocol will changes to tcp when the streaming client is in WAN.So that the NAT issue is automatically solved.Does we have the same option in gst-rtsp-server?Because when i use gst-rtsp-server as the streaming server ande quicktime as the client,i am not getting the video in client side.Similarly when using realplayer as the streaming client ,got segmentiaon fault in the server side.

Content-Type: text/plain
The second set of pre-release tarballs for Core, Base and Python are
available at:
http://gstreamer.freedesktop.org/src/gstreamer/pre/gstreamer-0.10.23.3.tar.bz2
http://gstreamer.freedesktop.org/src/gst-plugins-base/pre/gst-plugins-base-0.10.23.3.tar.bz2
and
http://gstreamer.freedesktop.org/src/gst-python/pre/gst-python-0.10.15.3.tar.bz2
These tarballs contain the following fixes on top of the first set:
* Fix some leaks and potential crashes in error cases
* Fix some API documentation
* Don't warn for empty tag strings in pre-releases and releases
* Serialise tags into the dataflow in basesrc
* improve buffering in queue2
* Add a private copy of input-selector in playbin2, removing the gst-plugins-bad dependency
* Fixes for adder required for upcoming pitivi release
* Wrap new API in the python bindings
Please test, and file any bugs in bugzilla: http://bugzilla.gnome.org
Expect the next set of pre-releases (if needed) on Friday, and the final tarballs on the 30th July
Cheers,
Jan.

That did it, thanks very much indeed. Your response also helped me find the
example in the "decodebin" section of the developer documentation that
refers to this method of pad connection.
Connecting the 'new-decoded-pad' signal from the decoder to a callback,
which then links the decoder to the sink when a pad is ready, does the trick
quite nicely (and I presume, now, correctly).
Thanks again, and by the way thanks also to everyone helping out the newbs
like me on this list. Sure, even the newbs around here still seem to
generally have some pretty good chops, but it's always nice to get a nudge
when you're stuck. :)
Thanks again and take care,
E. Westbrook
