My patch read movie, play when keyboard send one reference midi note (start) and send jumps when notes (and program changes) are pressed. The notes are the same for the other mac with patch MAX/MSP for sounds. All is ok, the Conductor of the ensemble can send informations at the keyboard (with score) and it's possible to play the pieces all around the world by others ensembles. But the problem is the "saccades" when we play movies, not regular, random !!!
I don't want transforming movie, just read correctly.
Thank if you can explain how play movies on this precise case with openGL.
