Hi List,
I'm currently wrangling with a problem, that seemed fairly straightforward
originally...
I have a chat application, to which I need to introduce a new feature that
allows the Chat Admin to switch the user that has the floor. This is done by
setting a flag in the chat so, which tells all the currently connected users
which of them has the floor. So far, so good.
But the user who has the floor, also needs to appear in the camera view for
all users, whereas in the original application you only had the Admin's
camera active.
My first idea was to simply switch the publisher - so if the Admin was
originally published as "adcam" stream, now the current floor user is
published there instead, and so forth. But that didn't seem to work - it
generated a "BadName" error. So then I tried to close the stream before
republishing, but that doesn't seem to work either, and I'm not entirely
sure why. I was tried to sending NetStream.close() and then I tried
NetStream.publish(false), but without success. I suspect that maybe the
client that started the process should also close it, but I'm not sure.
My second idea was to have them all published under their own usernames, and
switching to the floor user by playing the appropriate netstream. But for
some reason, I can only get "adcam" to publish, even though the other
streams are attempting to be played. The relevant code is this:
function setStream(newStream:String){
stream = newStream
}
function publishCam(newStream){
_global.tt("publish cam")
setStream(newStream)
if (Camera.names.length && parent.enableCam){
cam = Camera.get()
startCam()
_global.tt ("publishing", stream)
ns.publish(stream, "live")
}
}
function startCam(){
_global.tt("start cam")
broadcastMessage ("toggleCamMenu", "start")
broadcastMessage("attachVideo", cam)
ns.attachVideo(cam);
}
The Xray trace (_global.tt) is showing the right stream name, but it doesn't
get published.
So my questions are - can you see what's wrong with this code, and which of
the two approaches do you think would be a better design?
I should mention that this particular project is Flash7 / FlashComm Server
(not FMS).
Thanks,
Karina
