I have used the following properties in the meta data handler for finding the keyframes, but returned nothing:

var kfPoints:Object;
for (var propName:String in metaInfoObj)
{
if (propName == “keyframes”)
{
trace (“Keyframes received”);
var kfObject:Object = metaInfoObj[propName];
kfPoints = kfObject["times"];
}
}

How can I find keyframes in an mp4 file transcoded with an H264 codec?
