Capturing webcam images

Question

Hi,
I have flash working with flash media server to record a
webcam. There are two things I also need the application to do
which it currently doesn't.
1) How do you capture a still image from the webcam? At the
moment im using this line of code to record:
publish_ns.publish("allAboutMe + 1", "record");
2) How do you show what is being recorded as you record?, at
present it records with a blank screen and you cant see the results
until you play it back. This is the code used at the moment.
var my_nc:NetConnection = new NetConnection();
my_nc.connect("rtmp://localhost/allAboutMe");
var publish_ns:NetStream = new NetStream(my_nc);
publish_ns.attachVideo(Camera.get());
publish_ns.attachAudio(Microphone.get());
publish_ns.publish("allAboutMe + 1", "record");
thanks
Gavin

For starters, you should not call NetStream.publish() until
AFTER you receive a NetConnection.Connect.Success message from the
server. Failure to do so may prevent anything from streaming.
Create a new "onStatus" method as follows:
var my_nc:NetConnection = new NetConnection();
my_nc.onStatus = function (info:Object)
if(info.code == "NetConnection.Connect.Success")
// Publish your stream here
var publish_ns:NetStream = new NetStream(my_nc);
publish_ns.attachVideo(Camera.get());
publish_ns.attachAudio(Microphone.get());
publish_ns.publish("allAboutMe + 1", "record");
my_nc.connect("rtmp://localhost/allAboutMe");
To watch the video, you need to create a Video component on
the stage and then attach the camera as follows:
var video:Video; // Don't forget to create this component on
the stage!
video.attachVideo(Camera.get());
As for capturing a single image, I'm not sure how to do that,
but you can make the player display a single image like this:
your_netstream.play(yourstream, -1, 0);
The zero parameter tells Flash to play the stream for zero
seconds (i.e. 1 frame)
Good luck,
