video delay with jitter
Hello,
For an art project of a friend he asked me if i could make a patch where there is a live webcam input that is projected in a room with a delay on the output of the video.
The delay should be a minimum of 10 minutes and up to 30 minutes.
I had a try with the Delayr in Vizzie. There is only a delay of 120 frames.
I tryed to go into delayr to change this to 30 000 frames so I can get 10 minutes, but I am lost in the patch.
Can somebody help me out with this?
Maybe patching a delayr with 30 000 frames delay?
Thx in advance

Usually video delay is made by storing frames in VRAM (this is how Delayr or jit.fx.delay works), which is why it is often limited by a few frames or seconds of delay.
A delay of 10 to 30 minutes would requires a completely different approach, ie. writing the video feed into a file on disk, and read back that same file at the same time. I have no idea if or how it is possible with Max though.
FWIW, I think it can be done with ffmpeg or vlc, but then Max would mostly serve as a way to execute commands using [shell].
