More work needs to be done in libswscale to expose the colorspace
setting. Also we still need to complete the migration to the new
libswscale API. Once this is done then contrast/brightness may be set
through the scale filter.

*Or* you may have a look at the eq and eq2 MPlayer filters and port
them to libavfilter.
