MovieClip class

63

Example

The following example creates a new NetStream connection. Add a new Video symbol by 
opening the Library panel and selecting New Video from the Library options menu. Give the 
symbol the instance name 

my_video

. Dynamically load the FLV video at runtime. Use the 

attachAudio()

 method to attach the audio from the FLV file to a movie clip on the Stage. 

Then you can control the audio in the movie clip by using the Sound class and two buttons 
called 

volUp_btn

 and 

volDown_btn

.

var my_nc:NetConnection = new NetConnection();
my_nc.connect(null);
var my_ns:NetStream = new NetStream(my_nc);
my_video.attachVideo(my_ns);
my_ns.play("yourVideo.flv");
this.createEmptyMovieClip("flv_mc", this.getNextHighestDepth());
flv_mc.attachAudio(my_ns);
var audio_sound:Sound = new Sound(flv_mc);

// Add volume buttons.
volUp_btn.onRelease = function() {
    if (audio_sound.getVolume()<100) {
    audio_sound.setVolume(audio_sound.getVolume()+10);
    updateVolume();
    }
};
volDown_btn.onRelease = function() {
    if (audio_sound.getVolume()>0) {
    audio_sound.setVolume(audio_sound.getVolume()-10);
    updateVolume();
    }
};

// updates the volume
this.createTextField("volume_txt", this.getNextHighestDepth(), 0, 0, 100, 

22);

updateVolume();
function updateVolume() {
    volume_txt.text = "Volume: "+audio_sound.getVolume();
}

The following example specifies a microphone as the audio source for a dynamically created 
movie clip instance called 

audio_mc

:

var active_mic:Microphone = Microphone.get();
this.createEmptyMovieClip("audio_mc", this.getNextHighestDepth());
audio_mc.attachAudio(active_mic);
