I wanted to mix past images with present images from a webcam using pix_mix. Attached is a patch that successfully does this using pix_buffer and fails to do this using pix_delay. My question is, why doesn't pix_delay work with pix_mix in my patch? How woulld I change my patch to get pix_delay to get the same results as pix_buffer does?

Thanks,

-John
