This one is 88 lines, including comments and white lines, did you tried
to read it at all ?

https://cgit.freedesktop.org/gstreamer/gst-rtsp-server/tree/examples/te
st-launch.c

For the in/out parameters as you say, the API is fully documented
online. For each C function, lookup this side to find the details:

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-rtsp-serv
er/html/

When you build it, it works a bit like gst-launch-1.0, after all,
before starting a server you probably want to use gst-launch-1.0 to
figure-out the right pipeline. It's nice for quick experiment.

This the part I can't read, but I won't say it's totally undocumented
and missing tutorials, just that I have no idea what it means really.
What type of stream will this command provide ? Do you really want to
interface this ?
