Sorry, recompile what? Rpmbuild?

Seriously, I don't get your request. I guess you are asking someone to download jolla-camera sources (from where?), build the binary and give it to you. How is having rpmbuild on the device relevant? Why can't you build it yourself? Why are you assuming that some random person building it for you will yield a different result than Jolla building it? I am confused!

For what it's worth, I never realized that the camera light was new in Aurajoki. I found it entirely by accident and assumed it's always been there. I never found the need to use it.

Mind you, it is only available in the video mode:
