Comment (by spookybathtub):
R3D is an extremely complex codec, with dozens of raw processing
parameters that need to be specified, and color science that is under
heavy development by RED. Also, REDline takes advantage of the Red Rocket
hardware accelerator card for a huge speed benefit over CPU.
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. 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. But maybe I'm wrong.
