Replying to [comment:17 spookybathtub]:
> R3D is an extremely complex codec
codec? Isn't it just a relatively simple format with jpeg2000 in it?
> with dozens of raw processing parameters that need to be specified, and
color science that is under heavy development by RED.
Check out all the color filters in libavfilter, including lut3d.
> Also, REDline takes advantage of the Red Rocket hardware accelerator
card for a huge speed benefit over CPU.
I wonder what this has to do with the software implementation.
> The R3D SDK is kept up to date, and supports Red Rocket. But if
licensing prohibits that, then I suppose the alternative would be to write
a decoder from scratch.
Isn't the issue just about supporting some random pixel format, just like
with XYZ with D-Cinema? (recently added)
> In that case, it seems unlikely that ffmpeg developers could keep up to
date with the color science and perform the debayer and raw conversions
accurately.
lol
> But maybe I'm wrong.
Yes.
