[GEM-dev] [pix_buffer] crash Pd on Windows

[Jack]

Hello Max,

Thanx for your answer.
I forgot to write that the resolution of the movie is 480x360 pixels
(there was a mistake in my previous mail where i wrote 640 480), 4 bytes
per pixel.
There is 7300 frames in this movie.
So the size in RAM used should be :
480x360x4x7300=5045760000 bytes.
It should be enough because there is 6.4 Go free on my Windows system
(64 bits).
Or I miss something ?
On the same computer, but under Ubuntu 13.04 (64 bits) it works fine...
So, is it a memory problem under Windows ?

Jack
