Supported Colorspace

[volvet]

I got an error "Only YUV color space input jpeg is supported, Guetzli processing failed". Where can I find the supported colorspace list?

[robryk]

Could you attach the image where it failed?

This is a gray jpeg picture.

+1 for gray jpg support

I have a lot of color-space related errors when I try to run Guetzli "massively" on an existing project (can provide example files if needed). Does other color-space support is planned ?

(I try to know if coding a wrapper around guetzli falling back to jpegtran in case of error is worth the effort)

Same error for me on the attached picture.

Same as everyone else, fails on attached picture: scamp.jpg.zip

Error: Only YUV color space input jpeg is supported
Guetzli processing failed

[rogierlommers]

Anyone found out how to change input files in order to prevent these errors?

I found this comment to be really helpful: https://github.com/google/guetzli/issues/120#issuecomment-289190404

Worked when I made sure that my image was still tagged with sRGB.

You're seeing this error because your JPEGs are in grayscale mode. This has nothing to do with color profiles.

You can avoid this warning by converting the JPEG to a PNG first.
