Getting a flv file to start playing with no sound

Question

Hello,
I am trying to get my flv file to start playing when the page is loaded with no sound, but I am have no luck. The flv file starts playing fine with the sound on, and I can turn the sound off with my volume controller, but I need it to start playing with no sound. Please help.

Answer 1

you can use the soundmixer's soundtransform to control all volume but, unless you have multiple sounds, you should probably use the netstream's soundtransform.
in either case, to start your video with no sound, assign the volume property in you onMetaData function:
function onMetaData(data:Object):void {
var st:SoundTransform = videoStream.soundTransform;
st.volume = 0;
videoStream.soundTransform = st;
