[FFmpeg-devel] [PATCH v12 03/14] lavc/tiff: Convert DNGs to sRGB color space

[Nick Renieris]

> Why do you put all this color space convertion code into the decoders ?

The color space conversion needs to happen, camera sensor data is
linear. If it's not done images looks really dark as result.

> Colorspace and pixel format convertion is generally done outside decoders.
> The specification cannot specify what part of FFmpeg's code does the
conversion.

I had found some sRGB conversion code in libswscale, asked about using
it and was told not to.
It's only 4 simple lines, as opposed to probably more complicated code
to use libswscale or whatever.
