Description L. López 2014-09-06 15:00:40 UTC

Some avi files causes gstavi element to crash with a segfault.

All programs using gstreamer 1.4.1 are crashing due to this bug p.ex. totem or shotwell.

Those AVI are very old, +10 years may be, and were produced by cheap digital cameras from that time.

I also reproduced the bug with gst-launch. VLC can reproduce them without major issues. 

I have some samples to reproduce the bug but they are personal files and I'm not going to upload them. However I can send them individually to some developer.

If you could upload them somewhere (dropbox or so) and send me a link that would be appreciated, thanks.

The stack trace does not show the actual crash, please use 'thread apply all bt' next time so it shows all threads.

    This is a regression from 1.2 caused by the port
    to the pad flow combiner.
