I'm designing a web-embedded video player, my idea is that,
1. use VMR with windowless mode to render video.
2. use activex control window as VMR clipping window.

Then, I have to resize control according to actual video resolution.
Here's what I did,
1. read video file in, get its resolution;
2. set control size by use of SetControlSize(cx, cy) accordingly.

But it never worked. The control size was always the size passed in by
html.

What should I do?

BTW, I'm not sure that using activex control as VMR windowless
clipping window is good idea, any other suggestion?

Thanks.

PS.
I know this thread should fit mfc ole, but there's no people
discussing.

Without understanding much of what you're saying here, I'd say that
the control size is decided by <object> tag, (width, height
attributes) and you have no say in that from the control code. (It'd
be a horrible design if ActiveX controls could nilly-willy reformat
the HTML at runtime, wouldn't you think?)

You should be, however, able to use a browser script inside your html
to resize the <object> tag once you know desired size. Approaches that
come to mind: hook into HTMLElement's onreadystatechange, or create an
event in your control that you yourself fire when you first find out
about video size. Use size you get either from the control or from
your own event to resize <object> from your script.

HTH,
Goran.

Got your idea!
Fire up an event to html when figure out video size and let javascript
to resize!

Really appreciated.
