I have an NSMovieView displaying in a normal window, I was setting the
window's alpha level to get a transparent effect of the playing movie.
All is working great and it looks great but I came across a problem.
When the window is set to different alpha levels to get that
transparent effect you can see the first frame of the movie kind of
stuck there in the background. If the movie's first frame is a black
screen you can not see this at all. I was using a harry potter
trailer from quicktime.com as a test because the first frame is a green
screen with ratings, after playing I set the alpha level and there it
is, the green screen.
A little further information, if you attempt to resize the window with
the window resize widget, the image disappears but a new image is
created at the moment resize finished, kind of like a ghost image
effect. I experimented with this a bit and found out that if you do a
[window setFrame:frame display:YES]; it does not change anything but if
you use an animate. [window setFrame:frame display:YES animate:YES];
it gives the same result as using the resize widget.
Does anyone have any insight about this issue? Any ideas how to get
rid of that unwanted pictre?
Thanks in advance,
Chris
