[Android] [Appsink] [Appsrc] Strange behavior when displaying the receiving raw data via appsrc

[sofien rahmouni]

Hello Nicolas, 
I fixed my issue , it's was about the mtu value not setted in the rtp
payload *rtph264pay *: 
// Sample Send data APPSINK
            data->pipeline = gst_parse_launch(
                    "ahcsrc device=1 ! video/x-raw,format=(string)NV21 ! tee
name=t t. ! queue ! autovideosink sync=false t. ! queue ! video/x-raw, 
width=320, height=240 ! videoconvert ! x264enc bitrate=500 key-int-max=1 !
rtph264pay mtu=500 ! appsink name=callback_read_buffer_sink
emit-signals=true",
                    &error);

and the passed value from java

                        DatagramPacket dp = new DatagramPacket(msg,
msg.length);
                        ds.receive(dp);
                        //Send received frame data to native Gstreamer part
                       
nativeReceiveVideoData(Arrays.copyOf(dp.getData(),dp.getLength()));
 
but now i'm facing a new problem is video freez after some seconds, let's
see the log i found a warning about the timestamp and the rtpjitterbuffer
plugin.

here is my log :
