[Live-devel] MPEG4 streaming using ffmpeg as encoder

[ssingh at neurosoft.in]

Thanks for the input and i rellay appreciate your help. If i subclass 
ServerMediaSubsession than I need to implement other functions too. Is 
there a another class which will do most for me. I noticed that 
OnDemandMediaSubsession is being used for some subsession implementation 
but is it only for unicast or can i use it for multicast too. I am 
little confused as for what the ondemand media subsession is used.

Thanks,
