Re: [Gnash-dev] Video.width, Video.height

It really isn't available. Also, the actual initialization time of
Video.height (or Video.videoHeight in AS3), seems to be unpredictable in
the Adobe player, so SWFs often end up polling the value. The youtube
player does this a lot in Gnash, and I wonder if it's because it's
waiting for a value other than 0 or undefined. It would be easy enough
to find out with listswf_d, of course.

It is certainly possible with most formats (mpeg4, for instance, as it's
used in digital television). I don't know about FLV. I don't think this
case really requires a callback, as it's a simple query from the AS
Video class to the VideoDecoder when that information is required.
