[PD] A "multiple problem" with video playing
tep

Wed Jan 27 21:30:27 CET 2010
Hi
I'm using a few computers to play some synced videos, but i can't get
satisfying results using pix_movie.
The computers are ibooks G4, maybe they're too weak ? The movies are
720x576, .mov, photo jpeg codec.
Which codecs are the best, or "lightest" to use in pure data ? I don't need
to manipulate the movies, just play some different ones at different
moments, that's all.
