Are both your CPU cores loaded? yuvdenoise is a bit of a complicated beast I don't think it'd be easy to optimise.
A simple multithreaded optimisation technique is to use slices (less than full height sections of the frame, each section is given to a CPU) However yuvdenoise uses spatial gaussian filtering which would present problems at the slice boundary. The ffmpeg vfilter system makes use of slices. It may be easier to implement these filters using the ffmpeg vfilter system. (although the slice boundary problem will still exist) Does anyone know how to implement spatial filters using slices?
