Wel, not good, it's design has some serious issues, mostly to the fact 
that it is ony suited to announce MPEG-TS streams.

The problem with SDP is that it essentially is one of the worst formats 
i have EVER seen. Basically, it is very easy to handwrite a SDP for one 
type of stream, but it is extremely difficult to write and read a SDP 
by a more general system (VLC) to handle multiple types of video and 
options.

The amount of exceptions and methods of specifying things, in 
combination with the string based parsing, makes it almost impossible 
to accept everything that falls into the SDP standard.

But if you want to do plain and simple SAP announces, i suggest you 
look into the VLC code for SAP anonunces.
src/stream_output/announce.c
src/stream_output/sap.c
modules/stream_out/rtp.c

In current SVN, cause some changes have been made as of late.
