[vlc-devel] Support for ONVIF Profile G

[David R. Robison]

Thanks for the pointers. The reason for strings is because they match 
the arguments in the RTSPClient::sendPlayCommand command from the live code.

The only other approach I thought of was to use more command line 
arguments, but I was afraid of adding too many command line arguments 
and it would serve only the RTSP interface with the live555 code. Is 
there any other approach you can think of? From reading you post it 
seems there will need to be some structure to send data from the core to 
the different plugins, in this case the demux plugin. Has this been done 
before? Is there such a structure?

Thanks again for your response. David
