Some cameras have rtsp://ip/media?width=640&height=480&fps=30 - other cameras have profiles like rtsp://ip/axis-media/media.amp?videocodec=h264&streamprofile=highquality - others will not allow specifying quality/profile/fps at all in the URL.

These days, cameras that support ONVIF can be configured using WS-Discovery using a SOAP API over UDP e.g. http://stackoverflow.com/questions/13416193/how-to-discover-onvif-devices-in-c-sharp

Once again, this is nothing to do with live555 but rather with your camera manufacturer and how they decided to implement it.

I am sorry for the confusion.

I want to ask the camera to provide the mpeg/h264 stream at particular frame rate and resolution.

Most of the IP cameras will have the in build webserver where we can login to the camera web page and configure it.

During from my application I need to ask the camera to provide the stream with a particular frame rate and resolution irrespective of what is set in camera web page.

Since I am using the LIVE555 framework I would like to understand is there any mechanism or facility to achieve this.

For example.
The MPEG url could be
Rtsp://<IP>:<port>/mpeg4

I need to pass frame rate and resolution along with this.

I hope the question is clear.

Thanks and Regards,

I am using the LIVE555 Frame work for the IP camera streaming.

Basically camera is set for a frame rate and resolution. I can set these parameters in the camera web page.
But would like to stream the camera with my own framerate and resolution, this will be decided dynamically.

Unfortunately I don't think I understand your question.

You want to use parameters - that were passed to your camera's web server - to configure your camera's encoder (with a particular frame rate and resolution).  So just do this.  This has nothing to to with RTSP, and certainly has nothing to do with "RTSPClient".
