Can you provide a test application and stream to reproduce this? Also please provide a backtrace of all threads at the time when it freezes, and try if updating to 1.6.0 fixes this for you.

Comment 7 manasa.athreya 2015-10-28 08:52:38 UTC 
I have tested at TV end so I don't have test application.
The issue is thread lock is happening and its not sending flush stop event on encountering multiple seek events.
I tried to get logs in debug mode 5 ,I was not able to reproduce issue on enabling the logs.
I have only qtdemux logs which I have attached with respect another stream as that stream is very large I couldn't upload.

Comment 9 Sebastian Dröge (slomo) 2015-10-28 09:12:07 UTC 
Without a backtrace or an easy way to reproduce, you'll have to debug that yourself and try to get an understanding why it deadlocks. Then we can discuss possible solutions for this.
Comment 10 Tim-Philipp Müller 2016-05-22 22:10:55 UTC 
Can't reproduce this with git master (1.9.1) either.

Please re-open if you can still reproduce this with more recent versions of GStreamer, thanks!
