yep, me again :)
i get "error: Gem: pix object cannot handle gray image" when sending pix_movie(s) to pix_add... (same error with pix_mask too)
i'm using MJPEG coded videos (yes, they are in color. but i don't think this the problem)
(win2k, pd0.35-17, gem 0.85)
cheers -andre ps. maybe i should use pix_multiimage instead...
i found this in the docs:
Can't process pix_movie data with pix objects
POSTED 4/24/99
BUG: pix_movie sends the data immediately to OpenGL, so there is no chance to process the data. some geos don't render data from pix_movie correctly

Re: [PD] (GEM) pix_movie & pix_add ?s**t, in the docs, (spank me), thnx for still telling me what i've should found my self...

this is out of date. it is true for [pix_movie], BUT:: with [pix_film] you *can* do image-processing !
i get "error: Gem: pix object cannot handle gray image" when sending pix_movie(s) to pix_add...

there is the [pix_rgba] object that tries to convert all non rgba-formats to rgba which can then be processed by other objects, like pix_mask
i'm using MJPEG coded videos (yes, they are in color. but i don't think this the problem)
in fact, this is the problem, since normally movies will store data in rgb. to avoid overhead, pix_movie (and pix_film) do *not* convert the data to rgba-space. almost all pix-objects have methods for rgba-images (which are "colour" in Gem) but some do not have methods for other colour-spaces, like "rgb" (which are called "gray" -- though obviously they are not)
(win2k, pd0.35-17, gem 0.85)
well, ok. what i said above applies to gem-0.87 only. try it. there are no precompiled binaries for windows right now, but the sources (which can be found somewhere at ftp://iem.kug.ac.at/pd/Externals/GEM/LINUX ) should definitely compile under both windows and linux.

i do not think that this is a good solution for movies (when they are longer than some secs)
1000x thanks for the info, that helped ! momentarly i don't have any time to learn compiling it under windose :( (making 2videos for a musicDVD, and only 1week time:)
has some1 compiled it for win?
btw. are there any performance differences between pix_movie and pix_multiimage, lets say only to play a clip/images ?(i'm aware that pix_multiimage takes more mem, but pix_movie has to decompres)
cheers -andre
