This question, I know, is a huge endeavour. I would of-course be happy if someone had a solution for my question, but I guess that what I'm asking for is a helping hand, a point in the right direction, in order to achieve my goal.

I have been using Rob Ramirez's "jit.gl.hap" object lately. This is really a great way of working with hi-def video in real-time.

What I want to do is to use the AUVI objects "au.hc" and "au.feedback" and convert them into the world of OpenGL. So I can use the power of openGL for my playback and effects.

Does anyone have some pointers to how I can achieve this? I do not know shader programming and I'm not totally skilled in the world of openGL, but I understand some.

I would really really really really appreciate any tip, hint, solutions or what ever on my way to enlightenment on this subject.

here's a patch that uses a gl.pix cropper/zoomer i made a while back, along with a very basic feedforward/feedback gl.pix patch.

Thanks for the input Rob. Looking forward to checking the patch out!

This is great Rob, thanks. I could definitively work with this. Thanks again for the hap as well!

Why is the cropping not working when I'm using the cc.brcosa shader?

because the brcosa shader ignores the incoming alpha channel (all we're doing in the crop gl.pix is setting alpha to 0 for the cropped section).

either modify the brcosa shader to keep the alpha channel, or replace with [ jit.gl.pix @gen brcosa ], which keeps the input alpha.

another alternative is to modify the crop gl.pix so that it crops to black (0 0 0 0) rather than simply crops using alpha.

I'll try both solutions out. Thanks again Rob!

eh.... I tried to modify the crop gl.pix so that it crops to black (0 0 0 0) rather than crops using alpha..... but my knowledge about gen is minimal. Would it be possible to describe what I need to do?

here is a modified brcosa shader. it works with alpha channel.

hope it can help you


But I think that i need to find a solution where I can make the gl.pix crop to black in stead of using alpha. This has to do with the way I use the original cc.brcosa object.

Thanks, Francois
