Hello,
I want to stream a live video captured from camera device over a network using udp .
The details of setup I am using are as follows:
Ubuntu 18.20
iMX8Mini
and i'm using USB camera with UVC support and connected to i.mx8 via USB and want to stream via ethernet to System.
So, first i was trying with videotestsrc
pipeline on the server side:
gst-launch-1.0 -v videotestsrc ! jpegenc ! udpsink port=3445 host=192.168.60.103
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
