Stuck at 66% if video has no audio track

[MrLavender]

It really is a shame that this application is so poorly maintained. It's easily the best simple video trimmer and cutter if only the various "gets stuck at 66%" bugs were addressed.

My own use case is CCTV footage which doesn't have an audio track and VidCutter fails because it assumes that all video has an audio track... a PR which fixes this and other issues was submitted EIGHT YEARS AGO.

Anyway for now I just run this shell script to fix it every time my distro updates it. Only tested on Arch Linux.
