  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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 ?

  • How can I find out what this ffmpeg error code means ?

    27 septembre 2018, par Asik

    I’m using the function avcodec_decode_video2. On an encoding change in the stream, it returns -1094995529. The documentation only states :

    On error a negative value is returned, otherwise the number of bytes
    used or zero if no frame could be decompressed.

    But there doesn’t seem to be an enum of return codes or any other form of documentation. What does the error mean and how can I determine that in general ?
