Test case

Since upgrading to Fedora 17 gnome-dvb-daemon is not able to stream MPEG2 TS streams anymore. Creating a small example that uses a static pipeline did not work as well when using rtpmp2tpay. However, demuxing and using rtpmp2tpay works fine. I'm not sure whether that's a problem on the server or client side.

Turns out the culprit is commit 09f0860a1037b73bf314dd6d80ebbfa096ff93bf to gstmpegtsdemux.c (see bug 663756). After reverting it, everything works fine again.

Test case using sample.mpeg

I uploaded a sample file to http://k-d-w.org/clipboard/sample.mpeg and adjusted the test case to use this file. The result is as follows:

Does *not* work:
gst-launch playbin2 uri=rtsp://127.0.0.1:8554/test

Does *not* work:
gst-launch rtspsrc location=rtsp://127.0.0.1:8554/test ! rtpmp2tdepay ! mpegtsdemux name=demux ! queue2 ! mpeg2dec ! xvimagesink demux. ! queue2 ! mad ! alsasink

Does work:
gst-launch rtspsrc location=rtsp://127.0.0.1:8554/test ! rtpmp2tdepay ! tsdemux name=demux ! queue2 ! mpeg2dec ! xvimagesink demux. ! queue2 ! mad ! alsasink


For me the result should be that I can play the stream fine using playbin2. Unfortunately, playbin2 uses mpegtsdemux instead of tsdemux.
Comment 7 Edward Hervey 2012-05-30 10:11:41 UTC 
Since mpegtsdemux is no longer the primary demuxer in git, shall we just revert that patch ?

It works fine with tsdemux, so the upcoming release will have the fix anyway.
Comment 8 Sebastian Pölsterl 2012-06-01 07:28:39 UTC 
From my point of view it doesn't really matter.

In the meantime, is there a way to tell playbin2 to use tsdemux instead of mpegtsdemux until a new version is released?
Comment 9 Tobias Mueller 2012-10-04 13:21:49 UTC 
Reopening as I can't see any open non developer question.
Comment 10 Tim-Philipp Müller 2013-04-21 09:27:10 UTC 
I don't think this is going to get fixed for mpegtsdemux in 0.10 if it's still a problem, so let's close this. tsdemux works fine after all and is the only demuxer in 1.x
