How to embed color profile?

[dope...@gmail.com]

I've got some jpg images in sRGB with embeded color profiles. Images look as they should to for example in Chrome. If I convert them to webp using cwebp, colors look wrong (as if the embeded color profile would not be used at all). I've tried different options by conversion with no luck. If I use photoshop webp plugin to export images it looks as it should in chrome. If I open the image converted with cwebp (the one that looks wrong) in photoshop, convert it to sRGB and save it as webp (again with photoshop), it looks fine too.

So, how can a tell cwebp to use the color profile embeded in jpg? Thanks

Did you use the option: 'cwebp -metadata all ...' when converting with cwebp? (just checking).

Maybe the color profile included in the original jpeg is not detected properly by cwebp, not sure.

In case, could you please open a bug on the issue tracker here: https://bugs.chromium.org/p/webp/issues/list

The original jpeg and steps to repro would be very helpful...

thanks!
