ColorMatrix v2.3

ColorMatrix corrects the colors of mpeg2 streams of dvds. More correctly, those mpeg2 streams are encoded using a different set of coefficients as used by AviSynth's color conversion routines or by the XviD/DivX decoders, with the result that DivX/XviD clips or mpeg2 clips encoded by TMPGEnc/CCE using AviSynth or VirtualDub are displayed with slighty off colors (which looks like a small difference in brightness[*]). This can be checked by opening the mpeg2 stream directly in VDubMod. More info can be found in the readme.

This filter recalculates the yuv values assuming the coefficients which are used by AviSynth/VDub/DivX/XviD, with the consequence that your final encoding (mpeg2 or mpeg4) is displayed correctly.

Changelog v2.3 (by tritical),
- Calculate conversion coefficients for PB/PR rows from luma coefficients
- Added inputFR and outputFR parameters allowing for YUV range expansion/contraction
- Changed the clamp parameter from bool to int to allow specifying only pre clipping or only post clipping or both
