Hello,

I am trying to run 4 USB webcams at the same time and triggering each using fiddle and pix_video. I know fiddle is heavy on CPU but the other externals do not seem to work for me. Is there a way of easing this congestion?

hmm, the last time i had CPU-problems with [fiddle~] was on my P-100. which hardware are you using?

The piece tries to replicate CCTV monitoring so maybe only using 1 or 2 frames per second would be good. How do you do this and will it cut down on congetion?

you can create the [gemwin] with an argument which denotes the framerate; you can send a [frame $1( message to the [gemwin] to change the frame rate at runtime; you can turn on/off entire gem-chains by sending 1/0 to the initiating [gemhead]; you can use [spigot] to disable parts of the gemchain.

and you could use smaller frame sizes and greyscale images to reduce the amount of data from the webcams.
