Recording live broadcast

Question

My company uses broadcasts which include both streams (coming
from different users and sometimes displayed together), animations
amd images mixed together on the flash player.
You can think of it as kind of flash presentation mixed with
web meeting.
We would like to record the broadcast into a single video
file (flv, quicktime, etc.) and streaming this file on demand from
our FMS.
I am looking for a way to record what the broadcastig viewer
sees when he looks at the boradcast.

Answer 1

You can't do any sort of screen capture or anything like
that. What you CAN do is use netstream.send to trigger events in
the client.
Let's say, for example, you have a function in your
actionscript named playAnimation(), and a stream named someStream.
To trigger that function, your code might look something like this:
Client side:
function playAnimation(){
// do something here
my_netconnection.triggerAnimation = function(){
playAnimation();
On the server side:
application.tellClientToRunAnimation = function(){
someStream.send('triggerAnimation");
Now, when the server side function is called, a message goes
out across the stream, and tells the client to run the function.
Now, here's where it gets really cool. IF you're recording
the stream, the netstream.send call gets saved in the flv file. So,
when you play it back, the triggerAnimation call gets fired off
again on playback, at the same point in time at which you sent it
duing the live broadcast.
Of course, using this method only works if you play back the
flv in an swf that's set up with the proper functions. If the .swf
deson't have the functions you're calling with the netstream.send
event, nothing will happen.
Hope it helps.
