GstRTPNetCC - GstRTPNetCC Examples

The GstRTPNetcc was implemented to provide bandwidth estimations between endpoints, which establish a video streaming session. So these GstRTPNetCC examples are run between two devices:

Tegra TX2 and X86 machine

For testing purposes, the user can check the bandwidth estimation enabling the GStreamer to debug as follows:

--gst-debug=*rtpnetcc*:5

This will show these messages:
