And what is the purpose of FsRtpStream since all the job is done on
FsRtpSubStream ?

I finished the FsRtpSubStream diagram and updated the FsRtpConference one:

I was planning on documenting this on the send pipeline (FsRtpSession
diagram):

Can you explain better how the "discovery thing" works? (I'm taking a look
at the fs-rtp-session code, but somethings are hard to get).

The codecbin, blueprint, etc part is pretty hard to understand (if someone
wants to understand the final pipeline that will be built), is there a
reason why decodebin and encodebin are not used to build the send/receive
pipelines? it seems you use an autoconvert element and a list of factories,
never read about autoconvert before.
