I am doing a multicast streaming using RTP and the framerate is set to 30fps but i am receiving only 13 frames at the receiver end. How can i improve this

Transmitter command gst-launch-1.0 v4l2src device=/dev/video0 ! tee name=t ! queue ! videoscale ! 'video/x-raw,width=640,height=480, framerate=(fraction)30/1' ! videoconvert ! queue2 ! x264enc tune=zerolatency ! rtph264pay ! multiudpsink auto-multicast=true send-duplicates = true bind-port=5000 clients="255.255.255.255:5000"

Receiver command gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264 ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! videoconvert ! fpsdisplaysink sync=true -v

Hi Santhosh

for RTP one can look at sect.7.3.12 Real Time Streaming Protocol Linux Guide

in Linux 4.19.35_1.1.0 Documentation

and some examples on DART-MX8M GSTREAMER - Variscite Wiki 

Best regards

Hi igorpadykov,

Thanks for the links, I tried with the link that you have shared using the num-buffers=100 but still at the receiver end i am not seeing the 30fps, only 14fps are received. How can i get max frames transmitted without any lose at the receiver end

Looking forward for your support on this...

Regards
