[vlc-devel] Re: sdp

[Matthew Romaine]

Hussain,

take a look in modules/demux/livedotcom.cpp and do a search for 
"MPEG4-GENERIC". you should come across a sequence of else ifs that set 
some parameters based on the codec that livedotcom has determined will 
be in a stream. For MPEG4-GENERIC, there's a conditional that checks 
part of a config and stores the data in a "p_extra" field that can be 
read by the decoder when it gets there in the chain.

hth,
matt
