But where things really got interesting for the Intel/AMD processors was
the much faster 10-bit decoding of AV1 content with dav1d 0.6.0 for both Intel and AMD.
Very significant gains in this case.
In ffmpeg we can see
API: add AV_PKT_DATA_ICC_PROFILE to AVPacketSideDataType
and next few patches ....
comment in avcodec.h says:
+ * ICC profile data consisting of an opaque octet buffer following the
+ * format described by ISO 15076-1.
--end of quote----
pdf itself is huge, but hopefully other libs already have something?
v4 ICC Specification
This version is technically identical to ISO 15076-1:2010, which is available from ISO.
This is the most widely used version, first published in 2001.
Specification ICC.1:2010-12 (Profile version 188.8.131.52)
Image technology colour management - Architecture, profile format, and data structure
Strange enough, but website littlecms.com doesn't work for me ....
Anyway, hopefully no-one need to *print* films right now, so it all
will be about monitors and files..
I may misunderstand something, but whole point of color management
is to get same color on slightly different devices?
So, if you work with Monitor A and you have color profile for your monitor,
you can store this profile somewhere in image and now video file, and then
on load supported player/editor will auto-correct things, relative to another (monitor B)
output device, so you can work on colors across few monitors in different locations, say.
I may misunderstand this, never feel special need for such fine-tuning of colors.
