[FFmpeg-user] Using ffmpeg to stream IS desktop.

[David Peterson]

I really appreciate the advice.  I am most certainly a "follower" in this
realm.  I am a firm believer though that, "Where others go, I can
follow"...
My hunch is that the aggregation will be the easier part.  It is the need
to get multiple mobile devices to work.  So it is the IOS transmitter side
that seems to be hard.  I know that if I can use VLC to stream the desktop,
then we can do it with a custom ffmpeg build.
That being said, I am confident that Chromebooks, Android, Windows and
almost every other OS will allow VLC/ffmpeg to record the screen and
therefore stream it to the rtmp aggregation server.  My big problem, I
believe is IOS.  How can I capture an IOS screen so that I can then send it
to the aggregator?
Again, we have devised the system that works (a hardware HDMI transmitter),
and it is really easy.  It is just really ugly (3 or 4 parts), and we don't
have the means to make the transmitter small enough to be useable.

Thanks for the help!
