Description Bastien Nocera 2015-05-03 14:09:02 UTC

My ISP provides (nearly) all the TV channels through local RTSP streams.

This is implemented in grilo in the freebox plugin:
https://git.gnome.org/browse/grilo-plugins/tree/src/freebox

gstreamer1-plugins-good-1.4.5-2.fc22.x86_64
gstreamer1-plugins-ugly-1.4.3-1.fc21.x86_64

MPlayer can carry on playing the stream properly. In this particular case, the stream hung after a couple of seconds only.

Comment 2 Tim-Philipp Müller 2017-07-13 19:40:49 UTC

Does this still happen with recent GStreamer?

If so, could you also do a pcap capture by any chance?

Comment 3 Tim-Philipp Müller 2017-07-13 19:41:29 UTC

And also a stack trace of all threads perhaps, in case it's deadlocked.

Comment 4 Bastien Nocera 2017-08-16 14:36:59 UTC

I still see this with 1.12. Thread 13 in the backtrace looks like it's trying to do something. All the rest are blocking on GCond.

I was playing back "rtsp://mafreebox.freebox.fr/fbxtv_pub/stream?namespace=1&service=201".
