I would like to get the webcamera and audio working well
together. What I have done is taken the example code for the
webcamera and added in AudioSubscriber and AudioPublisher. The
first problem is performance is terrible. I have quality on the
webcam publisher set to 70. Most of the time I cant even hear the
audio from the other end. Each of these components is within the
same ConnectSessionContainer. I am not doing anything differently
to the SharedProperty as found in the example code. I looked around
on this forum for help but didn't really find what I was looking
for. Does anyone know how to do this correctly/efficiently? It
would be nice if the webcamera example also had audio. It doesn't
do a whole lot to have video and no audio.

Thanks!

Hi,

Is your ResizeableCanvas file ( that has the
ResizeableCanvas) class in the same location (directory) as you
code you pasted below? Your code looks good to me, just that I am
not sure where your ResizableCanvas class is. You need to tell me
where this class is. It is not a native flex or afcs class, so
where you have kept it.

Secondly , if you are using AfcsNameSpace, you can use
rtc:WebcamPublisher and rtc:WebcamSubscriber instead of defining
seperately the collaboration namespace.

Thanks

Just replace ResizeableCanvas with Canvas. It is another
class I got somewhere else.

Report · 3/3/09

Hi,

And also when you use Canvas instead of ResizeableCanvas, you
need to use mx:Canvas .

Canvas is a flex defined class.

If you are not using the examples provided in SDK, please
make sure you have all the classes with you.

Thanks

i don't find ResizeableCanvas in my project , there is not

You need to use mx:Canvas as it is Canvas is a inbuilt class

Hi Lionceau,

Unfortunately, we don't have resources to do interactive
debugging of your compile errors in the AFCS forums. If you have
question specific to AFCS, please do continue to post, but sending
your source code over and over to this thread with compile errors
isn't an effective use of anyone's time.

For Flex compile errors, please see the Flex forums :

Do continue to post AFCS questions - we appreciate your

Hi all

I also confronted with performance issue while tried to work
with video and audio pieces simultaneously - video stops showing
anything if audio stream arrived. I solved this problem only by
using separate rooms for audio and video (one room for video and
another one - for audio).
