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

what about sip servers? Most sip clients have the streaming functionality built 
in. that would also help in regards to user mamagement. 
You could maybe get a sip server that uses ffmpeg.

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!

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

would it not be easier to use an rtmp server to "aggregate" and have the 
students stream their desktops to it?

Thank you.  I have found some documentation with regards to this.  I was
wondering though, if there might be some example howto's on this.  My goal,
in our school is to build a way to allow several concurrent mobile devices
which include iPads to be able to cast their screens to an "aggregator"  PC
and show them on the overhead projector, kind of like a multiview screen
for multiple camera's.  We have devised a way using HDMI grabber cards, and
wireless access points with modified firmware and a USB port, to be able to
send their screen in the manner I have outlined, but I was hoping there was
some way to do it without hardware.
The hardware solution is really cool aside from the fact that their are 3
or 4 parts to the transmitter.

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

[dpeterson478]

Does anyone know if there are any ports of FFmpeg that have any hope of 
streaming or recording an iOS desktop?

Does avfoundation not work on iOS?
