  • FFmpeg convert .mov to .ogv

    24 juillet 2016, par Morten Hauberg

    I have some troubles converting my .mov to a .ogg file using FFmpeg.

    This command should work, right ?

    ffmpeg -i test.mov -s 640x320 -vcodec libtheora -acodec libvorbis out.ogv

    It gives me this output

    It seems right, right ?

    But the movie is only about 1 second long.
    Why is that ?
