Using gstreamer RTSP server over the internet

Tue Sep 5 19:23:34 UTC 2017

So Nikolas, the examples tells nothing how to connect the stream to the
input port or how to redirect to another address.

I ran it and got this:
>>./test-launch "( videotestsrc ! x264enc ! rtph264pay name=pay0 pt=96 )"
stream ready at rtsp://127.0.0.1:8554/test
<http://127.0.0.1:8554/test>

How can I feed it with a h264 stream and open it with another player? For
now I would be satisfied with this working on the localhost. I have some
mp4 and mkv files on this machine for testing if it is required to use
gst-lauch-1.0.

The ffmpeg comand captures the desktop, encode it with h264 and sends it to
the <Server IP>. This could be changed.
