I’m tweaking the final patch in the video processing series AB put up a while back. I want to replace the first source of video from jit.qt.grab to another poly~ / umenu list, so that I can simply mix two different channels of footage as opposed to live feed / footage. However, this causes the p texture-conversion subpatch to get unhappy and it will only play one or the other. I have tried opening different video folders for each list – yet each time only one will play back, and the other will display a white screen. Maybe this is a simple answer for an OpenGL whiz…hoping you can check out the tutorial/patch and let me know what’s going on.
