• Php-ffmpeg “Unknown encoder libfaac” on Windows

  6 mars 2016, par Dev

  I am using laravel 4.2.

  I am working on a project in that user can upload a video and I need to transcode it that it can be played over all kind of devices.

  For transcoding I have added php-ffmpeg package from git hub in my project. According to the instructions I have downloaded ffmpeg package from http://ffmpeg.zeranoe.com/builds and set the ffmpeg.exe’s path into the environment variable Path.

  Now, I tried code below to transcode an uploaded video :

  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($video_path);
  
  $format = new FFMpeg\Format\Video\X264();
  
  $format->setKiloBitrate(1000)
  
          ->setAudioChannels(2)
  
          ->setAudioKiloBitrate(256);
  
  $video->save($format, public_path().$path.$save_filename);

  But it gives error as below :

  {"error":{"type":"FFMpeg\\Exception\\RuntimeException","message":"Encoding failed","file":"F:\\wamp\\www\\ohvideo-ftp\\vendor\\php-ffmpeg\\php-ffmpeg\\src\\FFMpeg\\Media\\Video.php","line":168}}

  After searching alot, I found a link for the solution here, with note that

  Zeranoe’s ffmpeg does not contain libfaac support due to that encoder
  requiring —enable-nonfree which would result in a non-redistributable
  build.

  I don’t get the solution. Can anybody help me to overcome this ?

  Edit : (working code as below)

  I have created a CustomVideo class the same like class FFMpeg\Format\Video\X264() as below :

  class CustomVideo extends FFMpeg\Format\Video\DefaultVideo
  
  {
  
      /** @var boolean */
  
      private $bframesSupport = true;
  
  
  
      public function __construct($audioCodec = 'libmp3lame', $videoCodec = 'libx264')
  
      {
  
          $this
  
              ->setAudioCodec($audioCodec)
  
              ->setVideoCodec($videoCodec);
  
      }
  
  
  
      /**
  
       * {@inheritDoc}
  
       */
  
      public function supportBFrames()
  
      {
  
          return $this->bframesSupport;
  
      }
  
  
  
      /**
  
       * @param $support
  
       *
  
       * @return X264
  
       */
  
      public function setBFramesSupport($support)
  
      {
  
          $this->bframesSupport = $support;
  
  
  
          return $this;
  
      }
  
  
  
      /**
  
       * {@inheritDoc}
  
       */
  
      public function getAvailableAudioCodecs()
  
      {
  
          return array('libmp3lame');
  
      }
  
  
  
      /**
  
       * {@inheritDoc}
  
       */
  
      public function getAvailableVideoCodecs()
  
      {
  
          return array('libx264');
  
      }
  
  
  
      /**
  
       * {@inheritDoc}
  
       */
  
      public function getPasses()
  
      {
  
          return 2;
  
      }
  
  
  
      /**
  
       * @return int
  
       */
  
      public function getModulus()
  
      {
  
          return 2;
  
      }
  
  }

  and updated the code to transcode video as below :

  $ffmpeg = FFMpeg\FFMpeg::create();
  
  $video = $ffmpeg->open($video_path);
  
  $format = new CustomVideo();
  
  $format->setKiloBitrate(1000)
  
         ->setAudioChannels(2)
  
         ->setAudioKiloBitrate(256);
  
  
  
  $video->save($format, public_path().$path.$save_filename); 

  It has solved the Unknown encoder libfaac error.

• FFmpeg - ANR on large files when mixing video and audio

  8 août 2019, par spaceman12

  This command

  ffmpeg -i video.webm -i audio.m4a -c copy output.mkv

  will always produce an ANR error in android at the end of the conversion for any large files, say greater than 700mb.

  The ANR error is produced only at the finishing end of the conversion process after the output has been successfully generated, not in the middle or at the beginning etc.

  So I suspect it has got to do with some I/O stuff at the end.
  Can someone please shed some light into this, and help eliminate this ANR problem ?

• FFMPEG Error -1414092869 : Immediate exit requested

  8 juillet 2019, par Manity

  Hello i am using ffmpeg to play 4 videos at the same time.
  I am using a wpf/c# .net 4.7.2 wrapper for ffmpeg to do this.

  Occasionally get this error message, and the application just shuts down.
  there are no errors or exceptions thrown other than this one logged.

  Error -1414092869 : Immediate exit requested

  I have searched for a meaning to this error but can find nothing other than a vague reference to an android video player which does not provide me with any information at all.

  Can anyone shed any light at all, anything at all on the meaning of and cause of this above error and how it might be resolved ?.
