• Encoding failed during converting and saving video using php-ffmpeg in laravel

  6 octobre 2020, par mohammadreza mardani

  i'm using https://github.com/PHP-FFMpeg/PHP-FFMpeg package to convert user video uploads to mp4 format, note that I'm using Laravel framework for development process.
  
But I'm facing error for this and Im not really sure what im doing wrong because all it says is that Encoding is failed. I attached the errors image below you can see that at the bottom.

  



  This is my function which handles user uploads :

  



  public function upload()
    {
        $this->putVideoIntoStorage();
        $this->ffmpeg->saveVideo($this->storageManager->getAbsolutePathOf($this->video->getClientOriginalName()));

        return $this->saveVideoIntoDatabase();
    }



  



  This is the function which handles saving and converting video to mp4 using php-ffmpeg

  



   public function saveVideo(String $path)
    {

        $ffmpeg = FFMpeg::create([
            'ffmpeg.binaries' => config('services.ffmpeg.ffmpeg_path'),
            'ffprobe.binaries' => config('services.ffmpeg.ffprobe_path'),
            'timeout'          => 3600, // The timeout for the underlying process
            'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
        ]);


        $video = $ffmpeg->open($path);

        $video->save(new X264(), 'video.mp4');
    }



  



  This is the error im getting : Errors Image
  
I can provide more details if you need just ask me, I would be really glad if someone can help me through this.

  im having an issue while video mixing with audio. everytime when I try to make it.
That always give me an error which is

  


  


  Java.lang.RuntimeException : A cast to int has gone wrong. Please contact the mp4parser discussion group.

  


  


  Im using googlecode mp4 parser : implementation  com.googlecode.mp4parser:isoparser:1.1.22 and also tried that but no success implementation 'org.mp4parser:isoparser:1.9.41'

  


  Also on forum there's no proper answer on that question.

  


  here's my code

  


   public Track CropAudio(String videopath, Track fullAudio) {
    try {

        IsoFile isoFile = new IsoFile(videopath);

        double lengthInSeconds = (double)
                isoFile.getMovieBox().getMovieHeaderBox().getDuration() /
                isoFile.getMovieBox().getMovieHeaderBox().getTimescale();


        Track audioTrack = (Track) fullAudio;


        double startTime1 = 0;
        double endTime1 = lengthInSeconds;


        long currentSample = 0;
        double currentTime = 0;
        double lastTime = -1;
        long startSample1 = -1;
        long endSample1 = -1;


        for (int i = 0; i < audioTrack.getSampleDurations().length; i++) {
            long delta = audioTrack.getSampleDurations()[i];


            if (currentTime > lastTime && currentTime <= startTime1) {
                // current sample is still before the new starttime
                startSample1 = currentSample;
            }
            if (currentTime > lastTime && currentTime <= endTime1) {
                // current sample is after the new start time and still before the new endtime
                endSample1 = currentSample;
            }

            lastTime = currentTime;
            currentTime += (double) delta / (double) audioTrack.getTrackMetaData().getTimescale();
            currentSample++;
        }

        CroppedTrack cropperAacTrack = new CroppedTrack(fullAudio, startSample1, endSample1);

        return cropperAacTrack;

    } catch (IOException e) {
        e.printStackTrace();
    }

    return fullAudio;
}
