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:
