How can I config a WinRT component when using msInsertVideoEffect??

Question
-
When I transform a MFT to a WinRT component and plugin it with function msInsertVideoEffect. Because I can't get the instance, how could I pass the parameters for configuration with interface IInspectable?? If Javascript can't do this, does any way to do this with other programming language??

Kenny,
The MediaPlugins sample shows how to configure an effect:
in CustomEfect.js, see the function:
function getPolarEffectStartFunc(effectName) {
return function () {
// Set video element's source
var vid = WinJS.Utilities.query("#customEffectVideo")[0],
src = null;if (vid.readyState !== 0) {
src = vid.src;
}
vid.pause();
// Installing video effect with configuration in property set.
var effect = new Windows.Foundation.Collections.PropertySet();
effect["effect"] = effectName;
vid.msClearEffects();
vid.msInsertVideoEffect("Microsoft.Samples.PolarEffect", true, effect);
if (src) {
vid.src = src;
} else {
sdkSample.pickMediaFile([".mp4", ".wmv", ".avi"], [vid]);
}
};
}This allows you to set that property.

Hi Kenny,
Your object should implement Windows.Media.IMediaExtension. Then when you pass the propertyset (like in the sample) the SetProperty() method will be called.

Thanks for replying, but I still have a question. How the component get the value of the property set?? Does My MFT class need to inherit the interface IPropertyset and implement it or ??Tuesday, October 25, 2011 2:44 AM
