Question

I’m developing a video chat application using flex.
After some bandwidth check I want to resize the camera resolution based an the result of it.

But every second time I do that the camera frame freezes and I have to kill the flash player and reastart it. The camera basically crashes.

private var camera:Camera;


private function setCameraResolution(width:Number, height:Number):void {
    try {
        camera = null;
        camera = Camera.getCamera();

        if (camera == null) {
            infoPanel.title = "Error: ";
            infoText.text = "No Camera Found";
            infoPanel.visible = true;
            hideAllControllers();
            throw new Error("No Camera Found");
        }

        camera.setQuality(0, 80);
        camera.setKeyFrameInterval(15);
        camera.setMode(width, height, 24);
        camera.addEventListener(ActivityEvent.ACTIVITY, cameraActivityHandler);

        videoCamera.clear();
        videoCamera.attachCamera(camera);
    } catch (error:Error) {
        if (debug) {
            ExternalInterface.call('console.log', "Error: " + error.message);
        }
    }
}

By this point the camera isn’t attached to any NetStream. It only happens with some cameras and I’m working with a mac.
I checked it on other sites where they change the resolution as well and I never had a problem. It must be my code.

Thank you very much for your help

You should never change the camera resolution more then once.

Instead scale the component that you are using to represent the camera output.
