• Issue with video compression using HLS from laravel protonemedia/laravel-ffmpeg package

  29 mars 2023, par Mateo Kantoci

  I'm using laravel-ffmpeg package in order to compress videos and save it as .m3u8.
In another words, I have a job that is gathering all uncompressed files and compress them 1by1 and save them to google cloud storage. Furthermore, compression is using exportForHLS from package and throws an error :

  


  ProtoneMedia\LaravelFFMpeg\Exporters\HLSPlaylistGenerator::getStreamInfoLine(): Return value must be of type string, null returned in /var/www/html/ipaparazzo/vendor/pbmedia/laravel-ffmpeg/src/Exporters/HLSPlaylistGenerator.php:32


  


  In some cases compression works but my job is failing for most of the time.

  


  Anyone experienced similar issue ?

  


  P.S. It is working as expected when using public storage.

  


  This is my code exactly as per laravel-ffmpeg documentation :

  


  ->exportForHLS()
->setSegmentLength(10) // optional
->setKeyFrameInterval(48) // optional
->addFormat($lowBitrate, function($media) {
    $media->scale(426, 240);
})
->addFormat($midBitrate, function($media) {
    $media->scale(640, 360);
})
->addFormat($highBitrate, function($media) {
    $media->scale(640, 480);
})
->onProgress(function ($percentage) {
   echo "{$percentage}% transcoded\n";
})
->toDisk('gcs2')
->save($videoPath)
->cleanupTemporaryFiles();

• ffmpeg module saving not working after compression

  27 août 2022, par nickcoding2

  I'm just trying to save an mp4 to a different mp4 (before I even start playing around with the different compression settings). What exactly is going wrong here ?

  


  const ffmpeg = require('ffmpeg');

try {
    var process = new ffmpeg('./original.mp4');
    process.then(function (video) {
        video
        .save('./new.mp4', function (error, file) {
            if (!error) {
                console.log('Video file: ' + file);
            } else {
                console.log(error)
            }
        });
    }, function (err) {
        console.log('Error: ' + err);
    });
} catch (e) {
    console.log(e.code);
    console.log(e.msg);
}


  


  I get the following error :

  


  Error: Command failed: ffmpeg -i ./original.mp4  ./new.mp4
