crashes memory corruption segmentation fault

Hum, in this case, the only thing that I see, will be to update mlt. Follow this faq : https://answers.launchpad.net/openshot/+faq/1861

YOu could try to use the true version of ffmpeg : https://answers.launchpad.net/openshot/+faq/1040

But before do this faq : https://answers.launchpad.net/openshot/+faq/983

Same problem here. I'm on Slackware64 and I get this output in dmesg:

[39892.938714] openshot[18175]: segfault at 41 ip 00007faf74b30584 sp 00007fff83add9a0 error 4 in libpthread-2.20.so[7faf74b26000+17000]

It only happens after extensive cutting. I import a video, cut it a few times with the cutting tool and then click into the timeline - instant crash.

mlt is 0.9.2, ffmpeg is 2.4.3

Try to update your version of mlt.

I can't update, because I already have the very latest version.

>mlt is 0.9.2

https://github.com/mltframework/mlt/releases

I've updated to the latest GIT code of MLT now. I also compiled mlt without the option "--avformat-vdpau".

That seems to work better. It only crashed one time while I cut a video 50 times and moved the parts around.

So either the GIT code fixed it in the next official release or there's something wrong with my video card and vdpau. Thanks for the help. :)
