• Ffmpeg Symfony5 PHP8 [duplicate]

  11 septembre 2021, par Kévin Ducrocq

  I'm a french student learning web development, and how to create websites on Symfony 5.

  


  I've got this project to create a kind of Youtube website using Ffmpeg to convert and treat videos.

  


  However, when I try to use the "composer require php-ffmpeg/php-ffmpeg" command, it doesn't work and I really don't know what to do.

  


  here's the error I've got :

  


  PS C :\Users\Dev\Documents\Dev\Symfony\Youride> composer require php-ffmpeg/php-ffmpeg
Using version ^0.18.0 for php-ffmpeg/php-ffmpeg
./composer.json has been updated
Running composer update php-ffmpeg/php-ffmpeg
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  


  Problem 1
- Root composer.json requires php-ffmpeg/php-ffmpeg ^0.18.0 -> satisfiable by php-ffmpeg/php-ffmpeg[v0.18.0].
- php-ffmpeg/php-ffmpeg v0.18.0 requires doctrine/cache ^1.0 -> found doctrine/cache[v1.0, ..., 1.12.1] but it conflicts with your root composer.json require (^2.1).

  


  Use the option —with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

  


  Installation failed, reverting ./composer.json and ./composer.lock to their original content.
PS C :\Users\Dev\Documents\Dev\Symfony\Youride>

  


  thank you for your help, I'm a beginner... :)

  


• pthread : Avoid spurious wakeups

  18 octobre 2013, par Ben Jackson

  pthread : Avoid spurious wakeups
  pthread_wait_cond can wake up unexpectedly (Wikipedia : Spurious_wakeup).
  The FF_THREAD_SLICE thread mechanism could spontaneously execute
  
  jobs or allow the caller of avctx->execute to return before all
  
  jobs were complete.
  Test both cases to ensure the wakeup is real.

• Error with Laravel and FFMpeg in queue job

  19 octobre 2020, par user2916349

  I'm using Laravel with the protonemedia/laravel-ffmpeg package https://github.com/protonemedia/laravel-ffmpeg
I create a Job to handle video conversion and concatenation and this error appears :

  


  TypeError : Argument 1 passed to App\Jobs\VideoConversion::App\Jobsclosure() must be an instance of FFMpeg\Filters\Video\VideoFilters, instance of FFMpeg\Filters\AdvancedMedia\ComplexFilters given in /Users/fab/Sites/add-intro/app/Jobs/VideoConversion.php:43

  


  Here is the code of the Job :

  


  use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;

use App\Models\Video;

use Storage, Str, ProtoneMedia\LaravelFFMpeg\Support\FFMpeg;

use FFMpeg\Filters\Video\VideoFilters;

class VideoConversion implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $video;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct(Video $video)
    {
        $this->video = $video;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $filename = Str::uuid().'.mp4';
        FFMpeg::fromDisk('public')
        ->open(['intro.mp4', $this->video->path])
        ->addFilter(function (VideoFilters $filters) {
            $filters->resize(new \FFMpeg\Coordinate\Dimension(640, 480));
        })
        ->export()
        ->toDisk('public')
        ->inFormat(new \FFMpeg\Format\Video\X264)
        ->concatWithTranscoding($hasVideo = true, $hasAudio = true)
        ->save($filename);
    }

    public function failed(Throwable $exception)
    {
        FFMpeg::cleanupTemporaryFiles();
        dd($exception);
    }
}


  


  What I'm doing wrong ?
Thanks for help
