I did something, installed something, changed something, what i do not know, Everything came out of the stable and extra repos, but all my .mov files won't open. ffmpeg? i uninstalled and reinstalled. ffmpeg is not the testing version but stable 0.10. I also tried to reinstall every movie play that is on this machine by default. Still nothing opens, only when its put into openshot or kdenlive. I can preview and timeline watch. Before reinstalling yet again does anyone have any reason why this has happened, and anything i can try before wiping clean again.
