Thank you for your bug. First of all, could you please add information about which version of Ubuntu and ffmpeg you are using?
Second, when I run that command on a .avi file the only thing it does is to extract the sound as a .ac3 file. No video (m2v) files are created at all. Please check if you provided the right command. \TLE -- ffmpeg avi-mpg conversion stops updating UI https://launchpad.net/bugs/49377 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
