Ops... there's not my code into sources anymore :-|
you're using YUYV colorspace on VLC, is it the same as spc900?
into v4l2_base line 287:
if (!cropbuf) cropbuf = (unsigned char
*)malloc(2*crop.c.width * crop.c.height);
dest=cropbuf;
the destination buffer is pointing another one, which is being allocated
each frame, must check if it's "destroyed" after this, if not, it
consumes the whole memory in a short time at hi-FPS I think.
I may be wrong, hope this helps,
Ilia.
