[Live-devel] mpeg and user data

we have developed a streaming server based on live555, that gets mpeg4 
frames and streams them as a MPEG elementary stream.

Now I need to add some user data to each frame. I think that the correct 
way is to define a user data mpeg elementary stream, mux it with the 
video stream and add the resulting transport stream as a subsession to 

Is this idea correct? Can you give me some reference on how to build a 
user data ES and how to add it to the SDP (and other details that I am 
probably missing?).

Many thanks for any help.

Kind regards,
