• Get audio (M4A or MP3) file links directly from YouTube

  10 mars 2018, par Alex

  I am developing a PHP script that obtains video download links from YouTube. The ones I am grabbing are MP4 (720p) and MP4 (360p) (no-DASH format).

  My script is similar to this PHP class : https://github.com/Athlon1600/youtube-downloader

  It allows me to download any YouTube video that I want, no matter if it has copyright or not. It handles everything with signature ciphering and deciphering included.

  However, apart from videos, I would like to obtain audio download links from YouTube videos as well, either in MP3 or M4A.

  (M4A files are provided by YouTube, but they are in DASH format, which means, it’s not a complete file, but a collection of files that need to be merged together)

  Is there a way to obtain MP3 audio download links directly from YouTube ?

  I would like to avoid using FFMPEG library as it requires a lot of resources.

  In the case that using a library like that is the only option, what’s the most optimal way to convert MP4 files to MP3 files ?

  Is there any more efficient alternative than FFMPEG ?

  PLEASE avoid comments regarding YouTube TOS

• Laravel Jobs (redis/database) + FFMpeg = application/octet-stream

  20 avril 2019, par Andreas

  I discovered something very strange. Whenever I try to use FFMpeg within a queue using redis or database, my converted videos always turn out with MIME "application/octet-stream".

  Here is the weird part. When I use the exact same code, and change the QUEUE_CONNECTION to sync instead, my videos gets converted to "video/webm" just as instructed.

  Does anyone have a clue as to why this is happening ? I have also tried multiple approaches converting, with laravel-ffmpeg and php-ffmpeg. Now I am using regular ol’ exec("ffmpeg").

  Thanks in advance !

• Laravel Spatie - Spatie\MediaLibrary\Jobs\PerformConversions Job Failed

  5 février 2019, par Tout Nu Les Chinois

  I have an issue with Laravel Spatie’s media conversion OR Redis.

  I’m working in TDD, so all my test passed success, even conversion.
  For an input file sample.flv I have my files as expected..

  But when perform integration test my Jobs failed when they are queued.. (redis) And I have no logs.....

  Do you already have trouble with jobs and conversion ?

  job chained failed

  I am Using Laravel Spatie and Laravel-ffmpeg.

  The chained job

  ProcessPost::withChain([
  
              new AssociateMedias($post, $filenames),
  
              new AssociateTags($post, $tags, $user),
  
              new ActivatePost($post),
  
              new AttributeBadge('post', $user),
  
              new UpdateScore(100, $user)
  
          ])->dispatch($post)->allOnQueue('default');

  Here my Assoc Job

  public function handle()
  
      {
  
          array_map(function($name){
  
              $this->mediable->associate(UploadFiles::getTempDir() . $name);
  
          }, $this->filenames);
  
      }

  Here the assoc function in my Media trait

     /**
  
       * @param $path
  
       * @return Media
  
       * @throws DiskDoesNotExist
  
       * @throws FileDoesNotExist
  
       * @throws FileIsTooBig
  
       */
  
      public function associateVideo($path){
  
          $media = $this->addMedia($path)
  
                        ->toMediaCollection('videos');
  
  
  
          VideoConverter::toHls(
  
              'public',
  
              $media->originalPath(),
  
              $media->streamPath()
  
          );
  
  
  
          VideoConverter::toMp4(
  
              'public',
  
              $media->originalPath(),
  
              $media->downloadPath()
  
          );
  
  
  
          Storage::disk('public')->delete($media->originalPath());
  
  
  
          return $media;
  
      }

  And here my Conversion lib

  static function toMp4($disk, $path, $to) {
  
          $lowBitrateFormat = (new X264('aac'))->setKiloBitrate(500);
  
  
  
          FFMpeg::fromDisk($disk)
  
              ->open($path)
  
              ->addFilter(function ($filters) {
  
                  $filters->resize(new Dimension(960, 540));
  
              })
  
              ->export()
  
              ->inFormat($lowBitrateFormat)
  
              ->save($to);
  
      }
