Delayed frames when using AppSink (similar pipeline works with glimagesink)

Benjamin Behringer
Hi,

I already asked this question in the gstreamer-java group, but it might not be a problem related to the Java bindings: 

To my problem: the following gst-launch command fetches and displays my h264 video stream from my camera very well and without any delay (see the verbose at the end of this message):

gst-launch-1.0 -v rtspsrc location=rtsp://127.0.0.1:9099/vga latency=0 ! decodebin ! videoconvert ! glimagesink sync=false

I have a Java application where I use a similar pipeline, but with an AppSink instead. In fact, I use this sink to analyze individual sample images. Here's a snippet:

final Pipeline pipe = Pipeline.launch("rtspsrc location=rtsp://127.0.0.1:9099/vga latency=0 ! decodebin ! videoconvert name=mystream ");
AppSink videosink = new AppSink("GstVideoComponent");
StringBuilder caps = new StringBuilder("video/x-raw, format=RGBA, sync=false");
videosink.setCaps(new Caps(caps.toString()));
videosink.set("sync", false);
videosink.set("emit-signals", true);
videosink.set("drop", true);
AppSinkListener sinkListener = new AppSinkListener();
videosink.connect(sinkListener);
pipe.add(videosink);
pipe.getElementByName("mystream").link(videosink);
pipe.setState(State.PAUSED);
pipe.play();
pipe.setState(State.PLAYING);

My AppSinkListener receives the samples and writes them to disk (for testing purposes, i.e., I inspect each image manually):

@Override
public FlowReturn newSample(AppSink appSink) {
   final Sample sample = appSink.pullSample();
   final Buffer buffer = sample.getBuffer();
   final ByteBuffer newByteBuffer = buffer.map(false);
   if (newByteBuffer != null) {
      Structure capsStruct = sample.getCaps().getStructure(0);
      int width = capsStruct.getInteger("width");
      int height = capsStruct.getInteger("height");
      IntBuffer rgbBuffer = newByteBuffer.asIntBuffer();
      final BufferedImage renderImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_BGR);
      int[] pixels = ((DataBufferInt) renderImage.getRaster().getDataBuffer()).getData();
      rgbBuffer.get(pixels, 0, width * height);
      testWriteImage(renderImage);
   }
   buffer.unmap();
   sample.dispose();
   return FlowReturn.OK;
}

private void testWriteImage(final BufferedImage bufferedImage){
   new Thread(){
      public void run(){
         try {
            ImageIO.write(bufferedImage, "jpg", new File(
                  "/root/data/screenshots/" + globalCounter + "_" + Time.getTick() + ".jpg"));
         } catch (IOException e) {
            e.printStackTrace();
         }
      }
   }.start();
}

Notice that, I'll not write images to disk, but just process them in my final application. However, using the described approach I have a heavy delay of about 8 seconds. That is, I can move something in front of the camera, but the resulting images show the object after about 8 seconds.

Below, I attached the verbose output of gst-launch, which works fine.

Appreciate any ideas!

Cheers,
Ben
