Is it possible to do user defined SET_PARAMETERS/GET_PARAMETERS in rtspsrc?

[yiliang]

Hi,

I am using rtspsrc in our application to connect to RTSP server, which we can customize. If I would like to send/get some user defined parameters, like the brightness of the camera, using SET_PARAMETERS/GET_PARAMETERS, is this possible?

Also is it possible for the user application to get the status code that the server sends to rtspsrc?

Thanks for any helps!
