Comment 1 Hans de Goede 2013-03-06 16:48:10 CET

I'm afraid that just like bug 2710, I cannot reproduce this. It seems like both share the same underlying cause though, like the move from libav-0.8.4 to libav-0.8.5 ...

Comment 2 Hans de Goede 2013-03-06 16:49:03 CET

Hmm, or a problem with some other component in rawhide, since I'm on F-18 and you're on rawhide ...

Comment 3 Hans de Goede 2013-03-10 13:35:52 CET

This is likely caused by the same libav bug causing miscompilation with gcc-4.8 as bug 2710, iow
this is likely caused by:
https://bugzilla.libav.org/show_bug.cgi?id=469

A new gstreamer-ffmpeg-0.10.13-7.fc19 build which includes the fix from upstream livav, and thus should fix this is on its way to the development repository.
