• How to solve bad instruction `vadd.i16 q0,q0,q0' when attempting to check gcc for neon instruction

  Checking  gcc supports failed for neon instruction vadd.i16 q0,q0,q0

      int main ()

  Tried with flags -mcpu=cortex-a8 -mfpu=neon but stil no success

  Above code was used to test gcc support for neon instruction.

  Actually i am trying to build x264 with NEON support for ARM platformAfter running configure script
  x264 config log file contains

  Command line options : "—cross-prefix=arm-linux-androideabi-" "—enable-pic" "—extra- cflags=-mcpu=cortex-a8" "—host=arm-linux"

  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);
  
  }

  {
  
      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);
  
  }
  
  
  
  // //

      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);

      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.
