Switch audio on/off

[Arnaud]

Hi

I am trying to have an HTML link that allow the user to switch on/off
the audio of the videos shown on the home page. Is it possible? If so
what would be the adequate code?

The current code I am using to call the different videos is the one
below:
[
var flashvars = {
xml:'../swf/xml/data.xml'
};
var params = {
menu: "false",
scale: "noScale",
allowFullscreen: "true",
allowScriptAccess: "always",
bgcolor: "",
wmode: "transparent" // can cause issues with FP settings & webcam
};
var attributes = {
id:"flash_content"
};
swfobject.embedSWF(
"../swf/smartsy.swf",
"flash_content", "256px", "381px", "10.0.0",
"../swf/expressInstall.swf",
flashvars, params, attributes);

function playVideos(_id) {
if(!userAgent.match(mobile)){
document.getElementById("flash_content").playVideo(_id);
}

}
]


You can find the current page in dev here: http://184.73.230.170/en/index.html

Thanks in advance for your help.

So what is happening right now? The code above looks ok on first glance.

Does your swf have a js / ExternalInterface method defined called "playVideo()" ?

The videos are played correctly but I want to give the users the ability to switch audio off as it can be annoying sometimes. Beyond the function already mentioned, there is nothing else:

     function playVideos(_id) {
                       if(!userAgent.match(mobile)){
                               document.getElementById("flash_content").playVideo(_id);
                       }

       }

Can I mute/unmute the audio with javascript by clicking on a HTML link?

Your swf will need to have a listener for the JS call and will need the functionality to change the volume.

Thanks Nathan. How do I create a listener with the functionality to change volume?

You will need to have access to the fla file for the swf. Create a function to change the volume. Add an ExternalInterface.addCallback and set the name of the function as it's parameters.

Look up ExternalInterface to find some examples.

If you do not have access to edit the fla file, you won't be able to do it.
