• FFmpeg. avcodec_find_encoder(AV_CODEC_ID_H264) return false

  14 juillet 2016, par Иван Чванов

  The problem : I can not connect the h264 codec for encoding and decoding of frames.

  ---

  Description :

  I downloaded from here ffmpeg library https://ffmpeg.zeranoe.com/builds/, version dev.

  Connect it to your project QT :

  extern "C"
  
  {
  
      #include 
  
      #include 
  
      #include 
  
      #include 
  
      #include 
  
  }
  
      
  
  #pragma comment (lib, "avcodec.lib")
  
  #pragma comment (lib, "avformat.lib")
  
  #pragma comment (lib, "swscale.lib")
  
  #pragma comment (lib, "avutil.lib")

  Next prescribe av_register_all(); to include all codecs.

  Next, call the function : avcodec_find_encoder(AV_CODEC_ID_H264), returns false.

  In the ReadMe file, the library said that it was collected with —enable-libx264 and —enable-gpl compile the keys including h264 codec that is supposed to be.

  If the call : avcodec_find_encoder(AV_CODEC_ID_MPEG1VIDEO), it returns an object AVCodec, as it should.

  I use the MinGW compiler. OC Windows 7.

  How can I resolve or work around the problem ? Compile the library itself has not yet obtained. I understand you to connect sources and "poking" them, that too is meaningless.

  ---

  ** Once again, I will describe my problem : **

  I need to encode the codec h264 (can VP9) individual frames in one program, and then decode them in another program. You can use other libraries. The language C ++. It is necessary to use interframe compression codec, rather than simply pressed apart frames.

  Sorry for my english.

  Ideas. Advice. Suggestions.

• Encoding failed while adding watermark using ffmpeg in Laravel

  16 décembre 2020, par Ruturajsinh

  I'm getting an error while adding a watermark on the video in Laravel.
I'm using this protonemedia/laravel-ffmpeg package and I got reference code from here stackoverflow answer. I'm using the code from the first answer. If I do not add a watermark then it's working fine, but when I add a watermark I got an error.

  


  


  FFMpeg\Exception\RuntimeException : Encoding failed in file E :\xampp\htdocs\Learn\video-demo\vendor\php-ffmpeg\php-ffmpeg\src\FFMpeg\Media\AbstractVideo.php on line 106

  


  


  I'm using PNG image and MP4 video and I'm using first time this type of package so I don't know how to fix that and I didn't find any right solution.

  


  Please help me to fix that.
Thanks and also sorry for bad English.

  


  My watermark function :

  


  public function postVideo(Request $request)
{
    $video_file = $request->file('file');

    $ffmpeg = FFMpeg\FFMpeg::create();
    $video = $ffmpeg->open($video_file);

    
    $watermark = public_path()."/app_logo.png";
    $reqExtension = "mp4";

    if (!empty($watermark))
    {
        $video->filters()
              ->watermark($watermark, array(
                    'position' => 'bottom',
                    'top' => 25,
                    'right' => 50,
                ));
    }
    $format = new FFMpeg\Format\Video\X264();
    $format->setAudioCodec("libmp3lame");
    

    $randomFileName = rand().".$reqExtension";
    $saveLocation = public_path(). '/watermark/'.$randomFileName;
    $video->save($format,$saveLocation);

    if (file_exists($saveLocation))
        return "http://localhost:8000/video/$randomFileName";
    else
        return "http://localhost:8000/test/thumb/404.png";
    
}
