I don't know when we developers will officially release a new version of mjpegtools -- there's currently a coding frenzy around mpeg2enc and the denoisers. So you'll still have to get the latest CVS version in order to use y4mdenoise. But if you do, I just finished writing the first dual-processor version!
You control it with the new "-p" option. "-p 0" preserves the old behavior. "-p 1" moves the reading/writing of frames into separate threads. "-p 2" moves color-denoising into a separate thread. So far, that's as parallel as y4mdenoise gets. I can make it more parallel by making it denoise separate slices of the same frame in different threads, but that's going to be a LOT of work, so I figure I'd write this first & get it out there. I'm testing it on a dual-processor Athlon MP 2800+ machine. Even running the massive "near-perfection with videotapes" pipeline I posted to this list a few days ago, I can't quite fill up the processors -- total idle time hovers around 20%. But it's better than it was. And it's nice to see the main thread (the one denoising intensity) running near 100% CPU usage. Anyway, enjoy.
