Hi all,
I'd like to be able to control a video, and change very fast to different points in time. The reads will be almost exclusively of consecutive frames, but not necessarily ordered in an ascending way (go from second 0 to second 10,stop. go from second 10 to second 7, stop. go from second 7 to second 20, stop, etc).

I did some research and prototyping in processing, but playback of high resolution videos with jumps is impossible, the speed is awful. Totally unusable, and for what they tell me at the forums, there's nothing I can do to solve that.

What's the recommended way of doing that (speed is essential) in pd? I'd better stick to windows for now, so I don't have pdip available. Could GEM handle this well? Do you think I can achieve a good performance? What should be the issues and techniques, etc, i should take into account?

I don't know yet about the resolution of the video but I'm aiming at 640x480 or higher in order to get a "decent" image when projected on a wall.

Thanks!

Can you post your resulting patch so far? I would love to have a look at it.
I did a moviefader, and i know that video working is not quite nice.

If you can, try to have a look at GridFlow:

If you are giving up, then try vvvv:

It's much better for video purposes, it's its origin.

I finally went with vvvv for video, it's been great so far. Check some threads in vvvv forum where i asked questions regarding this problem, lots of useful info there. When the patches are finished i'll post them.

Best of lucks!
