RTP streaming from an TS MPEG2/AC3 file source?

[Chuck Crisler]

First it is very helpful if you mention the version of gstreamer and the OS
that you are using.

Second, you have rtpbin.send_rtp_sink_0 twice in the first part of the
pipeline. Is that intentional? It can't be good.

Third, from my experience, *EVERY* time that you get an error about a link
without a source it is because of branching some how and using improper
syntax.

I also wonder if your pipeline would work better if you specified caps?

Good luck. Please post more.
