Hi João,
actually those patches won't help you so much, as it aims at very short samples/videos up to about 8 seconds, depending how much memory your graphics card has. But they may give you an idea how to proceed. It's definitely not a good Idea trying to load a long HD movie in a [gemframebuffer] it might even crash gem if the memory on the card is not sufficient. but try if h.264 (compression) in pix_film runs smoothly enough (that may also depend on the OS you are on). If anyone disagrees with above please chime in.

Hi list,
I have almost no experience with GEM, so I wanted to ask around about this. I have a patch that should play 3 HD films, in the following way:
- the main patch plays the sound, and sends the frame-infos around through
OSC
- the frame-infos are received by 3 video player patches (each in one
separate Pd instance), each one playing one film
- the films are a bit heavy: 1/3 full HD = 640x1080pix each, around 6m long
(maybe more). The playing speed is around 25fps, sometimes less, sometimes more
- the hardware has a SSD disk, and i5 quad processor > 2,7Ghz (I can't say
yet much about the graphic card)
Which object is more adequate to play these videos in GEM? Probably isn't a good idea to load the videos into RAM. The playback is also very variable: forward, backward, something else... That means, is there a buffer-setting that would help in this case? And, under this context, how fast could the video be played?
Thanks,
João
