  • 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 ?

    I do not have access to ffmpeg2theora, so please dont suggest that :)

  • Video length missing in FLV converted by ffmpeg-php

    19 janvier 2013, par Andrew

    I'm converting MP4 videos to FLV using ffmpeg-php on my CentOS server (without intervention from flvtool2 because it's not installed).

    The FLV videos are created, but no player is capable of retrieving the video duration, this creates serious issues when trying to seek the video. I'm using the player created by Moyea's Flash Video MX Pro, but the problem also happens with other FLV players as well, so I'm sure that ffmpeg-php is not createing the FLV with the proper length data.

    My MP4 videos are compatible because ffmpeg-php CAN get the video length properly from then, yet it does not apply that length information into the FLV file. I assume flvtool2 is ONLY to retrieve meta-data and has nothing to do with the output FLV video length, let me know if this is correct.

    This command I use for conversion :

    $command = "ffmpeg -i myvideo.mp4 -ar 22050 -ab 64k -f flv -s 320x240 -y myvideo.flv";
    
$result = @shell_exec($command);

    This is my ffmpeg-php version :

  • ffmpeg error creating thumbnail different frame rate

    18 décembre 2012, par KJS

    When using this at the command line I get very bad images with only grey or stripes in them.
    It seems "the frame rate differs from container frame rate : 59.94 (60000/1001) -> 29.97 (30000/1001)".

    Is there any way I can fix this in the ffmpeg statement ?
