Since a few days I'm trying to install an video editor on my Notebook with Linux Mint Petra. But they are all very unstable and crash after a few minutes.
When i start for example OpenShot in the terminal i get this error in the first line: "Failed to import 'from openshot import main'"
and the last entry when it has crashed is:
"python: /build/buildd/libav-0.8.7/libavutil/mathematics.c:80: av_rescale_rnd: Assertion »b >=0« failed.
I get this error on most of the video editors (kdenlive,...) and i searched in the internet but can't really find a solution for this problem.
I hope you can help me!
