[FFmpeg-devel] xvYCC Conversion to Wide Gamut RGB with FFmpeg

Is it possible to convert xvYCC to wide gamut RGB using FFmpeg?

Is it possible to specify a high precision 3D LUT as tool for conversion?

Such as the open specification of described here
http://yesgrey.com/ycms.html and discussed on the forum at Doom9.

My query is based on the understanding rightly or wrongly that a typical
conversion to RGB uses only the 16 - 235 & 240 chroma range and that this
relates to sRGB gamut. That xvYCC gamut is potentially 1.8 times wider and
that a wide RGB gamut such as AdobeRGB is required to 'hold' the converted
data to do a 'proper' conversion.
