Hi all,

I need to sync my shader processing chain on the arrival of a new image of pixels_video.

For that i looking for an object or abstraction that send a bang when the image changes in the up stream.

Does anyone know a good solution for that ?

what do you mean by "change"?

the 2nd-last outlet of [pix_info] should give you the information whether a "newly acquired" image is sent down the pipe. this newly acquired image might be identical (pixelwise) to the last one.

if you want a pixel-wise comparision, try [pix_movement]/[pix_mean_color].
