What do you mean by "some threading". I am particularly interested in the input modules (cameras),

pthread is used in [pix_film], [pix_image], [pix_movie], and also in the V4L, V4L2 and DV4L modules of [pix_video]. Pthreads may also be used implicitly by some other classes or modules that I don't know about.

A lot of Quicktime codecs and capture drivers use multiple CPUs very well.  Every DirectShow filter is on its own thread.
