On Windows we don't ship the OpenSSL code. It's dynamically linked and we tell 
users to install it themselves from here

Anyway, as I already mentioned, we can rewrite these bits to use some other 
library; it's nothing special. I won't bother without any clear need though, 
and right now there is no need. If mplayer/ffmpeg decide to adopt librtmp, 
then I'll have a reason to move ahead on that.
