Hello,

You could try to modify the end of your command to: autovideosink sync=false
But if you will also want to play audio it may not be synchronized.

cheers! 

I have pipe line that receives RTP packets and display the video: 

 udpsrc uri=udp://localhost:5000 ! "application/x-rtp, media=(string)video,
clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" !
gstrtpjitterbuffer latency=1000 ! decodebin2 ! autovideosink 

I can see the video but: 

when the latency is smaller than 1000 the quality very bad. allot of packet
drops, gray\ green screen.. 

when the latency is 1000 the video is o.k but occasionally (every 5\6
seconds) the video is suddenly gray\ green and I get: 

    WARNING: from element
/GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0/GstD3DVideoSink:autovideosink0-actual-sink-d3dvideo:
A lot of buffers are being dropped. 

    Additional debug info: 
    gstbasesink.c(2873): gst_base_sink_is_too_late
():/GstPipeline:pipeline0/GstAutoVideoSink:autovideosink0/GstD3DVideoSink:autovideosink0-actual-sink-d3dvideo:There
may be a timestamping problem, or this computer is too slow. 



is there something else I can do beside changing the latency? maybe add
other elements? 

thanks in advanced. 
Leon.
