FLASH® LITE™ 2.x - Adobe Help and Support

The Flash Video Exporter utility (version 1.1 or greater) embeds a video's duration, creation
date, data rates, and other information into the video file itself. Different video encoders
embed different sets of metadata.
This handler is triggered after a call to the NetStream.play() method, but before the video
playhead has advanced.
In many cases the duration value embedded in FLV metadata approximates the actual
duration but is not exact. In other words it will not always match the value of the
NetStream.time property when the playhead is at the end of the video stream.
Availability
ActionScript 1.0; Flash Player 7
Parameters
infoObject:Object - An object containing one property for each metadata item.
Example
The code in this example starts by creating new NetConnection and NetStream objects. Then
it defines the onMetaData() handler for the NetStream object. The handler cycles through
each named property in the infoObject object and prints the property's name and value.
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.onMetaData = function(infoObject:Object) {
for (var propName:String in infoObject) {
trace(propName + " = " + infoObject[propName]);
}
};
ns.play("http://www.helpexamples.com/flash/video/water.flv");
This causes the following information to be displayed:
canSeekToEnd = true
videocodecid = 4
framerate = 15
videodatarate = 400
height = 215
width = 320
duration = 7.347
The list of properties will vary depending on the software that was used to encode the FLV
file.
