Description clinton 2012-08-30 18:52:30 UTC

Steps to reproduce:

1) Attempt to play the attached video in Totem.

Notice that a crash occurs; a backtrace reveals that it happens in dca_syncinfo() of libdca.

Comment 1 clinton 2012-08-30 18:54:50 UTC

It turns out that the video in question is too large to attach to the bug report; please send email to clinton@yorba.org for a copy of it.

Comment 2 Tim-Philipp Müller 2012-08-30 19:12:32 UTC

Perhaps you could make the file available on a web server somewhere ?

Also, could you provide a stack trace with full debugging info please ?

And which exact version of a52dec and liba52 is this with ?

Comment 3 Adam Dingle 2012-08-30 21:34:17 UTC

I've uploaded the video in question to

Comment 6 Wim Taymans 2012-12-13 12:34:54 UTC

doesn't seem to crash anymore here.

Comment 7 Jim Nelson 2013-01-05 00:33:54 UTC

This one crashes Totem with gstreamer-0.10:

Comment 8 Tobias Mueller 2013-05-08 13:53:07 UTC

well. I get "The stream is in the wrong format".

Comment 9 Jim Nelson 2013-05-08 20:37:55 UTC

What version of GStreamer are you using, Tobias?

I believe this is fixed w/ GStreamer 1.0.

Comment 10 Edward Hervey 2018-01-15 10:39:08 UTC

Closing. If the file still doesn't work with recent gstreamer(1.12 or master), please re-open.
