Hi! Sounds great!
Rawstudio expects uncorrected data, scaled to 0-65335 (whitepoint), or alternatively 16 bit linear (gamma 1.0) data with an attached colorspace (like Prophoto). The former is greatly preferred, since it allows DCP profiles to be set on the images. I think each plugin links to the depending modules like libjpeg, so they (in theory) can be separated out, if unavailable. We can of course only accept the code if it is (L)GPL v2 (or compatible - that does not include v3) for licensing reasons. Whitebalance picker depends on a selected DCP profile. I cannot say why it is failing without the code. I cannot remember if it works on embedded profiles. At the very least the metadata update sounds great! I can look at the code, and see why it isn't as fast. If you are interested, I could also look at integrating it into Rawspeed.
