i don't post very often but today it's for an emergency

is it possible to make transparent a part of a videoplane ?

i want to have an output that looks like the attached image ; which 

should also be the mask i would use (which match the screens shape)

I planed to do it with 3 videoplanes with masks but the mask show or 

hide parts of the video but i still have the rectangular shape (which 

i'm not really into opengl things and i think it should be a solution 

if someone has an idea it'll be very welcome

(doing it with matrix is very slow)

but i can't figure out how....

I'm pretty sure you can use the co.alphablend.jxs shader in jit.gl.slab. I

was going to say to use other shapes to cover the videoplanes, but I'm

thinking that might not work. If you want to do that, you should just make

it all automatic 0 and control the banging order.

i don't know exactly what you are trying to achieve (your image attachment never made it to the forum), but i found two patches which were recently posted on the forum, which might help you out.

videoplane & alpha (very urgent...)
