xvYCC in x264 or other encoders?
Say,
Is there support for encoding H.264 with xvYCC in x264 or other generally available H.264 encoders? http://en.wikipedia.org/wiki/XvYCC It may just be a matter of setting a metadata flag correctly, as long as the encoder doesn't clamp the chroma range or something. |

Doesn't look like it's supported in the current version of x264. Ron

There was a patch adding BT.2020 to the Colour Primaries a few days ago.
One of the newly added Transfer Characteristics was IEC 61966-2-4: http://mailman.videolan.org/pipermai...ne/010127.html |

I see xvYCC is in there as well: IEC 61966-2-4. I look forward to doing some tests in the next few weeks! |

I never understood why xvYCC couldn't be shoe-horned into Blu-ray when the format was launched coincidentally with the spec.
I think Sony is doing something with xvYCC now, but it's particular to using a Sony Blu-ray player and Sony HDTV. |
