Tjibs

I haven't been working with Max/Msp/jitter for a long time yet, but am enjoying it so far. I'm working on a visual installation where three movies will playback with different playback rates. The rate is changed by the brightness of the incoming image from a camera, using jit.qt.grab and jit.3m. I'm first trying to get things working with one video.

This works fine, and the movie plays well. Except the audio!

It'll play for about 16/17 seconds, before it starts stuttering heavily for a second, and then just stops. If I then change the playback rate to -1, I'll have sound again, and if I go back to 1, sound will play fine for another 16 seconds.

I've tried to play the movie with a constant rate, but this makes the audio crash as well. If I use loadram, the audio will play for 25 seconds before crashing. The video will continue to play fine either way. I've tried uncompressed audio, and compressed, but uncompressed seems to work better.

Am I just doing something incredibly stupid, or forgetting something?

Please do help.

use cocktail of jit.movie (vol 0 if audio still exists on

quicktime file) and SFPLAY (SFPLAY to playback audio).

Jit.qt.movie with constant changing rate, audio crashes?
