OpenGL + video with transparent background + Jit.gl.Hap

Dear Everybody,

I’m under a bit of time pressure, and will therefore ask a humble question :)

I have a bunch of videos I want to run using jit.gl.hap. Everything works fine, until today, where I found out that I have to key out a bunch of backgrounds.

I want to use the jit.gl.hap encoded with HAP-ALPHA, but I don’t get how to make OpenGL show my video with the alpha mask I have applied..

Any help will be very greatly appreciated.. A solution could also be using other OpenGL stuff, and not jit.gl.HAP, but it’s a little heavy on the computer, so HAP will be great!

Hope to hear from you (btw. OpenGL in jitter – and in general – is really new, so I might need a little bit of a newbie explanation :)

All the best,
Lasse
