[santhosh2]

Hello, I am trying to change the aspect ration and seems thats its working but i am seeing lot of dataloss and there is delay. How to do this properly gst-variable-rtsp-server -p 554 -m /video_1 -u "v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080 ! videoscale ! video/x-raw,width=1280,height=800, pixel-aspect-ratio=11/10 ! videoconvert ! vpuenc_h264 ! rtph264pay pt=96 name=pay0" Regards Santhosh

why did you set pixel-aspect-ratio as 11/10? any reason or you just want to test this? normally we use the command pixel-aspect-ratio=(fraction)1/1 in the command, if you want to change this, you also can add this parameter in the dts file.
