Question

我试图通过网络摄像头捕获视频并使用AIR将其转换为RTMP流。但是我无法找到这样的任何示例。有什么方法可以这样做吗？请给我实现这一点的一些例子。我是ActionScript的新手，我正在使用ActionScript，我在ActionScript中看过Camera api，但它无法正常工作，可能是我错误地实现了。

最后我发现了一种从网络摄像头捕获视频并将其传输的方法。正如我所说的，我想要它AIR，所以我创建了一个ActionScript类来实现它。

package {
    import flash.display.Sprite;
    import flash.events.NetStatusEvent;
    import flash.media.Camera;
    import flash.media.Microphone;
    import flash.media.Video;
    import flash.net.NetConnection;
    import flash.net.NetStream;
    import flash.net.Responder;
    import flash.text.TextField;

    /**0...
     * @author BECKER Christophe
     */
    public class Main extends Sprite {
        //
        public var vid : Video;
        public var cam : Camera;
        public var bt : Sprite;
        public var txt : TextField ;
        public var microphone : Microphone;
        private var connection:NetConnection;

        private var outStream:NetStream;
        public var nc : NetConnection;
        public var responder : Responder;
        private var inStream:NetStream;
        private var inVideo:Video;
        public function Main() {
            connection = new NetConnection();
            connection.client = { onBWDone: function():void{ trace("onBWDone") } };
            connection.connect("rtmp://Ipaddress/TestApp"); 
            connection.addEventListener(NetStatusEvent.NET_STATUS, onConnected);

        }
            private function onConnected(event:NetStatusEvent):void {
        if(event.info.code == "NetConnection.Connect.Success") {

            if(Camera.names.length>0){
                cam = Camera.getCamera();
                cam.setMode(640, 480, 15);
            }
            if(Microphone.names.length>0)
                microphone = Microphone.getMicrophone();

            outStream = new NetStream(connection);
            outStream.attachCamera(cam);
            outStream.attachAudio(microphone);
            outStream.publish("DemoVideo1","live");


            vid = new Video(300, 300);
            vid.attachCamera(cam);
            addChild(vid);

//          inStream = new NetStream(connection);
//          inStream.play("DemoVideo1");

//          inVideo = new Video(250,250);
//          inVideo.attachNetStream(inStream);

//          addChild(inVideo);



                            }
        }


        private function metaDataHandler(meta : Object) : void {
            if (vid) {
                vid.width = meta.width;
                vid.height = meta.height;
            }
        }

    }
}
