Hi Marius,
thanks for the answer,
i tried in the order you suggested but i have the same
effect.
With 'alpha on/off' i mean sending 1/0 with [tgl] to the
left inlet of [alpha].
I tried also different video formats (including the
homer.avi in gem examples) but nothing.
I made a new patch only to find the bug in this process, so
i don't have any more objects that the ones that i draw in
the previous e-mail and the [gemwin] with its proper
messages.
really strange...

Hi all,
here is Marco, this is my first post.. glad to be here.
i'm trying to use the [alpha] object to mix different
videos using OpenGL. I followed tutorials, checked the
forum and the list but i still have this problem:
I can change the transparency of a geo without texture,
and everything works also when i load images. But when i
add [pix_film] or [pix_movie] and i load a video the geo
itself disappears - if alpha is on - and appears again
(displaying correctly the video) when alpha is off.
I also tried to change [pix_texture] with [pix_texture2]
and [rectangle] with other geos, but nothing...
I think this is pretty strange.
this is my basic patch not working:
[gemhead]
|
[pix_film]X[t f]
|
[pix_texture]
|
[alpha]
|
[colorRGB]
|
[square]
That should work. even if the order is a little strange,
because I would put the alpha and color before the
pix_texture, but it is working here and I also have an
ATI Radeon X1600 (MacOS). what do you mean with turn
alpha on/off? are you setting the alpha by sending a
value between 0 and 1 to the rightmost inlet of colorRGB?
are there additional things in your patch which could
cause the problem? marius.
Cannot understand if it could be a problem of my graphic
card - ATI Mobility Radeon X1600 - or something else.
I work - unfortunately - on windows xp pro, with
pd-extended latest stable release.
i didn't have the chance to try the same on another
computer, by now.
Thanks a lot to everybody..
cheers...
Marco
