I can't find this documented anywhere...

This works just fine:

1) With the document open in the Flash authoring tool, in the Library panel (Window > Library) select New Video from the Library options menu to create a video object.
2) Drag a video object from the Library panel onto the Stage. This creates a video object instance.
3) With the video object selected on the Stage, in the Property inspector (Window > Properties) enter myVideo in the Instance Name text box.
4) Add this code:

myUrl = "example.flv";
//
var myNetConnection:NetConnection = new NetConnection();
myNetConnection.connect(null);
//
var netStream:NetStream = new NetStream(myNetConnection);
//
myVideo.attachVideo(netStream);
netStream.play(myUrl);

But I want to replace steps 1-3 with something like:

_root.myVideo = new Embedded Video ("myVideo", 1, 20, 20, 320, 240);

Is this possible?

In fact what is done while you perform these steps are:

1) a VideoStreamHead tag is inserted into the timeline;
2) it is placed on a stage with the name you assigned for it.

As for a programmical creation of a video object -- nothing is easier. Just define a VideoStreamHead tag with some predefined width and hight parameters and place it to the stage with the PlaceObject2 tag providing a name for the VideoStreamHead tag. It is very easy to create an SWF using any open-source Flash SDK available on the Net.

As for scripting (using ActionScript) I doubt it is possible, at least at present. Unfortunately video is not a component, therefore you have no way to setup its width and height (which are just readonly in runtime, but you can adjust them in designtime).

Why you need to _create_ it in a script? Do you need to change its dimensions?

I'm using a for loop to dynamically create menu items with thumbnails.

I had hoped to use flvs instead of swfs for the thumbs, so that where I would say:

var thumb = this.createEmptyMovieClip("thumb"+i etc.
thumb.loadMovie("thumb"+i+".swf");

I could instead say:

var thumb = this.createNewVideoObject("thumb"+i etc.
thumb.attachVideo("netStream"+i);

but from what you say it looks like I'll have to use swfs for the thumbs after all...?

Sorry, what is the problem? Are your thumbs of the same (width x height)? if so, nothing is easier! Just create a template "video.swf", containing such video object, load it into every thumb and play with all them. You can even stretch videos (create thumbs of various sizes) though I'm not sure how fast it will work for a couple of thumbs.

Please note that you may access the video by its instance name, though it is not a movieclip. This is very useful exception!

OK?

I have been obsessed with the idea of the entire site being generated by one page of actionscript... now I'll have to load in a swf and that makes me feel just dirty, dammit.
