[GEM-dev] can't get pix_movie working

[Matteo.sistisette]

Hi,

I am a user, not a developer, so I hope I'm not OT here, it is the only
gem-specific m/l I know of.

I am on Windows XP, on a Core Duo, with PD 0.40.1.

Up to yesterday, I was using GEM version 0.90, the one that is listed here
http://gem.iem.at/download.html as the current windows version, though it
dates back to 2004.
The attached patch worked perfectly, though GEM often crashed when closing
the patch, or opening it again, or when loading the video file the n-th time
with n>1. Which used to happen with just any patch using pix_movie.

Now I have installed version "gem-CVS20060914-W32-i686-bin", and the
attached patch doesn't work at all!

The main patch is test_onevideo_simple.pd, it uses the abstraction
onevideo.pd which is also attached.

It is supposed to load a video and play it looped at full window size.
It used to work fine on the old gem version.

Now, on the new gem version (nothing else changed), the rectangle appears
white without the video as a texture, and at every frame (when the frame
number is sent to the right inlet of pix_movie), the following error message
is printed on the main PD window:

"GL: numeración no válida" which means "GL: invalid numbering"

I suppose the message is generated by the operating system or some driver
since I am on a spanish machine.

The frame number that is input to the pix_movie is just correct (which is
obvious, since the patch is unchanged).


Any idea?

I hope someone will help.
