Can't get EOS using RTP/RTCP

[Steven Presser]

Edip,

While I appreciate the thought in your answer, a timed wait is not the 
right way to handle a race condition - which is ultimately what using 
the on-bye-ssrc signal to inject an EOS is.  Nor will it work in my 
(exceedingly time sensitive) application - it would introduce notable 
lags to the user.

I've tried using idle waits (as you have), but the on-bye-ssrc signal 
fires before any of my (canned) audio makes it through the RTPBin - 
meaning the pad is already idle.  If there isn't something I'm missing, 
it seems like this is a bug.  It would take a couple thousand lines of 
(C) code to work around this from the outside. From the inside its 
probably a couple dozen at most to examine state when sending RTCP 
packets (which is where the UDP sink for RTCP gets its EOS) or to 
examine RTP packets and see if they've all arrived yet.
