Sam.Richards@taurich.org 677cf95ea4 Initial checkin of OCIO filter. 
Initial checkin of OCIO filter.

Initial checkin of OCIO filter.

Signed-off-by: Sam.Richards@taurich.org <Sam.Richards@taurich.org>

Change for the right C++ library, should work on linux too.

Signed-off-by: Sam.Richards@taurich.org <Sam.Richards@taurich.org>

Adding inverse when using display/view.

Removed comments.

Removed code that was setting the CICP values. Hopefully this can be done through OCIO at some point.

Config cleanup - need a modified require_cpp to handle namespacing.

Switch to using require_cpp so that namespace can be used.

Adding documentation.

Sadly a bit of linting went in here, but more importantly added a threads option to split the image into horizontal tiles, since OCIO was running rather slow.

Make the min threads 1 for now, reserve 0 for later if we can automatically pick something.
Also added a few comments.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
