  • Revision 4e2732c3c3 : Separate encode_block for pass 1 and 2 The encode_block for pass 1 takes simple

    23 octobre 2013, par Jingning Han

    Changed Paths :
     Modify /vp9/encoder/vp9_encodemb.c



    Separate encode_block for pass 1 and 2

    The encode_block for pass 1 takes simpler functionalities and can
    save a few branches. The main reason is to make encode_block only
    used after running rate-distortion optimization search in pass 2,
    hence allowing dual buffer stack approach later.

  • Displaying RTSP-Stream using Xuggler : org.ffmpeg - [h264 @ 15AC7660] error while decoding MB 34 60, bytestream (td)

    10 avril 2016, par Wenonah

    I’m new to displaying RTSP-Streams and Xuggler, so I really don’t know what to do.

    I’m trying to display the Main-Stream of my IP-Camera in a Java-Swing Window and get this :

    enter image description here

    I also get these errors :

    This is part of the code that I use :

    private IMediaListener mediaListener = new MediaListenerAdapter() {
    

    
    @Override
    
    public void onVideoPicture(IVideoPictureEvent event) {
    
        try {
    
            BufferedImage bi = event.getImage();
    
            if (bi != null)
    
                updateWindow(bi);
    
        } catch (Exception ex) {
    
            LOG.error("Error getting Image from IVideoPictureEvent: " + ex);
    
        }
    
    }
    
};
    

    
public DisplayWindow() {
    
    display();
    
}
    

    
private void display() {
    
    IMediaReader mediaReader = ToolFactory
    
            .makeReader("rtsp://user:password@192.168.1.22:554/Streaming/Channels/1");
    

    
    mediaReader
    
            .setBufferedImageTypeToGenerate(BufferedImage.TYPE_3BYTE_BGR);
    
    mediaReader.setQueryMetaData(false);
    
    mediaReader.addListener(mediaListener);
    

    
    openWindow();
    

    
    while (true) {
    
        IError error = null;
    
        if(mediaReader != null){
    
            error = mediaReader.readPacket();
    
            if(error != null){
    
                LOG.error("Error at mediaReader.readPacket(): " + error);
    
            }
    
        }
    
    }
    
}

    Displaying the Sub-Stream (which has lower resolution) works well.

    I use Xuggler 5.4 with Maven.

    There probably is a simple solution to this problem, but I’ve searched the whole internet and haven’t found one, so I’d appreciate any help. Thank you !

    UPDATE : I’d also be happy about (free !) alternatives to Xuggler.

    What could be the reason behind this ?
