Strange,
when i use pix_yuv -> anything it made this kind of strange artefacts ....
if i reconvert with pix_rgba, these shit keeps goings:



All these red and green block have nothing to do with the original picture...

Do you know why it happens , and how i could fix it ?

i'm sorry neko, i have no idea of the answer, but THAT is a great picture!

i personally enjoy the ' < what the fuck? '
i have seen markings like those before when i am working with pixel type stuff. it looks like it's not using pixel data for the whole image...like it's repeating a part of it (but not the right amount of). if i have some time i'll look at some of my GEM stuff and see if i can figure anything out.

some word in this let understand that yuv is not really supported on both win32 and Linux GEM

then, i have no found any way out with this...
We have done with this bug, raw style
Gem on windows have to stay with 3D stuff, i think next time i'll use Pidip for these video purpose.

... and if you are in Paris, you could check the patch run here
...if it haven't crash... hehe

YUV works fine on linux/w32 (but is not directly supported by the openGL-drivers, so an additional conversion has to be done)

the artefact you are encountering is due to non-clipped parts in the RGB->YUV (and/or vice versa) conversion.
this has been fixed in the CVS version.
