when i try to read still image and display it on gl.videoplane,
i get white screen or sometimes image gets gradually distorted (like
with some old school vj fx – its sort of moving despite the fact its
just a jpeg)
i`ve tried to do an example patch but everything works fine in small
because my patch is quite big using maybe 50 different textures,
and all gl stuff makes me think maybe there is something wrong with
the hardware (ram?)
is it possible?
i`m on powerbook 12 1.33 768ram (GeForce FX Go5200 64vram) os x.3.9
While it’s possible that VRAM is the culprit (if you have a lot of
textures), you might be hitting the instruction limit for the card’s
programmable pipeline. If you are using a bunch of jit.gl.slab objects,
you might try consolidating your shader programs.
I’ve used about 100 512×512 textures with no problems (static images).
Check that your textures are above the minimum size for your graphics
card – I think that 16×16 or 32×32 (there’s a post on it somewhere in
the list archives). I just ran into this problem where my textures
were too small and showed up as either white or random noise.
Resizing them fixes it.
