 Summary of the bug: XYZ to RGB colorspace conversion use only sRGB matrix
 and sometimes the conversion is deffected in red channel and the picture
 is dark.

 Hi all!

 Is it possible to add more color space matrix (in option) to XYZ to RGB
 conversion? Because the FFMPEG use only one matrix (sRGB) but lots of
 available, and best if the user can choose one.
 Because the problem is: sometimes the conversion is deffected the red is
 much more and the picture is dark.

 If possible please add some from this list. The default is the sRGB but
 optional the others.
