Unable to set the Range header to the RTSP stream

Hello fellow streamers,
I attempted to stream video using the gst-launch

gst-launch-1.0.exe rtspsrc name=source location=rtsp://stream_url

I want to set the Range header here. I am fine with any values be it npt or clock, but unable to set those. I tried a lot of options like extra-http-request-headers, signal before-send using the gstreamer-sharp as well but all in vain.
Some good soul kindly help.

While I haven’t used it myself, I believe you need to listen to before-send, that let you modify the message before it’s being sent. Use appropriate GstRtspMessage API for the task.
