Gstreamer Pipeline sometimes doesn't work and sometimes does.

[Dimitrios Katsaros]

You can check the rtp caps on the broadcast pipeline if you are using
gst-launch with the -v flag. That should give you the rtp info you are
looking for. Also try to print out the fialing pipeline debug info by using
--gst-debug. you can start with --gst-debug=*:3 to get some info if there
is any available and then further explore the problematic element.

Also, what do you mean that the pipeline does't work? Is it producing
broken results or none at all? If you are getting no results, does starting
up the consumer pipe before the producer, does it work normally? An
important detail with h264 streams is that you need a key frame to start
streaming so make sure that the encoder is producing key-frames on
reasonable intervals.
