• Comand failed error with ffmpeg Node.js library

  24 juillet 2020, par msrumon

  I have a VPS of 2-core CPU and 2GB of memory. I am using this ffmpeg library to convert a video at a lower resolution and apply watermark. The app gives me this error :

  Can someone help me understand what this means ?

  


• xuggler : no video in encoded 3gp file

  1er août 2012, par khizar

  i am trying to encode videos into 3gp format using xuggler, i somehow got it to work, work as in the program stopped throwing errors and exceptions, but the new file that is created does not have any video. Now there is no error or exception for me to work with so i have stuck a wall.
  EDIT : Note the audio is working as it shud.

  This is the code for the main function where the listeners are configured

  IMediaReader reader = ToolFactory.makeReader("/home/hp/mms/b.flv") ;

      IMediaWriter writer = ToolFactory.makeWriter("/home/hp/mms/xuggle/a_converted.3gp", reader);
  
  
  
      IMediaDebugListener debugListener = ToolFactory.makeDebugListener();
  
      writer.addListener(debugListener);
  
  
  
      ConvertVideo convertor = new ConvertVideo(new File("/home/hp/mms/b.flv"), new File("/home/hp/mms/xuggle/a_converted.3gp"));
  
      // convertor.addListener(writer);
  
      reader.addListener(writer);
  
      writer.addListener(convertor);
  
  
  
      while (reader.readPacket() == null)
  
          ;

  And this is the code for the convertor that i wrote.

  public ConvertVideo(File inputFile, File outputFile)
  
  {
  
      this.outputFile = outputFile;
  
      reader = ToolFactory.makeReader(inputFile.getAbsolutePath());
  
      reader.addListener(this);
  
  }

  private IVideoResampler videoResampler = null;
  
  private IAudioResampler audioResampler = null;
  
  
  
  @Override
  
  public void onAddStream(IAddStreamEvent event)
  
  {
  
      if (writer == null)
  
      {
  
          writer = ToolFactory.makeWriter(outputFile.getAbsolutePath(), reader);
  
  
  
      }
  
  
  
      int streamIndex = event.getStreamIndex();
  
      IStreamCoder streamCoder = event.getSource().getContainer().getStream(streamIndex).getStreamCoder();
  
  
  
      if (streamCoder.getCodecType() == ICodec.Type.CODEC_TYPE_AUDIO)
  
      {
  
          streamCoder.setFlag(IStreamCoder.Flags.FLAG_QSCALE, false);
  
          writer.addAudioStream(streamIndex, 0, 1, 8000);
  
      }
  
      else if (streamCoder.getCodecType() == ICodec.Type.CODEC_TYPE_VIDEO)
  
      {
  
          streamCoder.setFlag(IStreamCoder.Flags.FLAG_QSCALE, false);
  
          streamCoder.setCodec(ICodec.findEncodingCodecByName("h263"));
  
          writer.addVideoStream(streamIndex, 0, VIDEO_WIDTH, VIDEO_HEIGHT);
  
  
  
      }
  
      super.onAddStream(event);
  
  }
  
  
  
  // //
  
  @Override
  
  public void onVideoPicture(IVideoPictureEvent event)
  
  {
  
      IVideoPicture pic = event.getPicture();
  
      if (videoResampler == null)
  
      {
  
          videoResampler = IVideoResampler.make(VIDEO_WIDTH, VIDEO_HEIGHT, pic.getPixelType(), pic.getWidth(), pic.getHeight(), pic.getPixelType());
  
      }
  
      IVideoPicture out = IVideoPicture.make(pic.getPixelType(), VIDEO_WIDTH, VIDEO_HEIGHT);
  
      videoResampler.resample(out, pic);
  
  
  
      IVideoPictureEvent asc = new VideoPictureEvent(event.getSource(), out, event.getStreamIndex());
  
      super.onVideoPicture(asc);
  
      out.delete();
  
  }
  
  
  
  @Override
  
  public void onAudioSamples(IAudioSamplesEvent event)
  
  {
  
      IAudioSamples samples = event.getAudioSamples();
  
      if (audioResampler == null)
  
      {
  
          audioResampler = IAudioResampler.make(1, samples.getChannels(), 8000, samples.getSampleRate());
  
      }
  
      if (event.getAudioSamples().getNumSamples() > 0)
  
      {
  
          IAudioSamples out = IAudioSamples.make(samples.getNumSamples(), samples.getChannels());
  
          audioResampler.resample(out, samples, samples.getNumSamples());
  
  
  
          AudioSamplesEvent asc = new AudioSamplesEvent(event.getSource(), out, event.getStreamIndex());
  
          super.onAudioSamples(asc);
  
          out.delete();
  
      }
  
  }

  I just cant seem to figure out where the problem is. I wud be thankful if someone wud plz point me in the right direction.

  EDIT : If i see the properties of my newly encoded video, its audio properties are set and its video properties are not i.e in video properties, dimension= 0 x 0, frame rate= N/A and codec= h.263. The problem here is the 0 x 0 dimension.
