Problems with mpegtsmux -> filesink always stopping immediately.

[Michael Prendergast]

I am working on an open source media server project that wraps gstreamer and am trying to debug a pipeline that contains an rtp source and an mpegtsmux and filesink.

The full server boot logs are available here:

https://drive.google.com/file/d/0B9eZJKieRdJPeHVheEtyRmNUWlk/view?usp=sharing

The elements of interest are mpegtsmux2 and filesink2. The filesink creates the file correctly but does not write anything to the file. I think the issue is with the timestamps in the stream. Below are the log lines that show the filesink stopping. Any guidance as to how to fix or get better debugging info would be much appreciated.

Hi Michael,

May I ask what media server project you are working on ?

Thanks,

Aaron

Sure,

I'm trying to add MPEG-TS recording support to the Kurento Media Server,
