  • PHP FFMPEG not working when I upload mp4 file

    9 août 2013, par Chris

    To convert video to formats compatible with HTML5 video I wrote the following script :

        $srcFile = "name/of/the/video.mp4";
    
    $destFile = "/media/video/newfilename";
    
    $ffmpegPath = "/usr/local/bin/ffmpeg";
    
    $flvtool2Path = "/usr/local/bin/flvtool2";
    

    
    // Create our FFMPEG-PHP class
    
    $ffmpegObj = new ffmpeg_movie($srcFile);
    
    // Save our needed variables
    
    $srcWidth = makeMultipleTwo($ffmpegObj->getFrameWidth());
    
    $srcHeight = makeMultipleTwo($ffmpegObj->getFrameHeight());
    
    $srcFPS = $ffmpegObj->getFrameRate();
    
    $srcAB = intval($ffmpegObj->getAudioBitRate()/1000);
    
    $srcAR = $ffmpegObj->getAudioSampleRate();
    
    $srcVB = floor($ffmpegObj->getVideoBitRate()/1000); 
    

    

    
    // Call our convert using exec() to convert to the three file types needed by HTML5
    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libx264 -vpre hq -vpre ipod640 -b ".$srcVB."k -bt 100k -acodec libfaac -ab " . $srcAB . "k -ac 2 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".mp4");
    

    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libvpx -r ".$srcFPS." -b ".$srcVB."k -acodec libvorbis -ab " . $srcAB . " -ac 2 -f webm -g 30 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".webm");
    

    
    exec($ffmpegPath . " -i ". $srcFile ." -vcodec libtheora -r ".$srcFPS." -b ".$srcVB."k -acodec libvorbis -ab " . $srcAB . "k -ac 2 -s " . $srcWidth . "x" . $srcHeight . " ".$destFile.".ogv");

    It is supposed to take any input video type and convert it to mp4, ogv and webm. When I run the script on a .mov file it returns a mp4 and ogv file, but not webm. When I run it on a .mp4 file it returns no converted files at all. Is there something wrong with the way I am converting the files ? Any help ?

  • ffmpeg : create interlaced output from progrssive input

    6 février 2012, par user1190908

    I have a 720p60 (54.94 to be exact) clip that I would like to scale down and output in 540i30 (27.97 to be exact).

    Here is my command line :

    ffmpeg.exe -i clip720p60.m2t -ss 90 -t 30 -vcodec libxvid -s 960x540 -b 1000k -r 29.97 -acodec libmp3lame -ar 22050 -ab 64k -f avi clip540i30.avi

    Stream #0.1: Audio: libmp3lame, 22050 Hz, stereo, s16, 64 kb/s
    
...

    The first options indicates to encode 30s at 90s past the start.

    Whatever options I tried up to now always end up with a video stream of 60s and an audio stream of 30s in the output clip.

    Can any one help me ?
