[FFmpeg-user] rgb2xyz filter

[laurie hughes]

Hi
First time for me on a mail list, so here goes….

I am researching DCP creation and I came across this page on the web http://www.michaelcinquin.com/library/ffmpeg.
it has a note at the bottom saying
rgb2xyz filter is now obsolete, as FFmpeg has xyz built-in

I am taking this to mean that there is no need to patch and that there is a xyz filter to convert from rgb (or other) to xyz colourspace.
but I cant seem to find any evidence of this in the documentation.
Does anyone know of this feature, or should I be trying to patch?
Thanks in advance
