I have a new GoPro HERO5 Black action camera. This GoPro is the first one, that is able to save photos in a raw format. Sadly GoPro did not use DNG as file format but invented a new one. From the FAQ:
The .GPR format is an extension Adobe’s .DNG format, adding enhanced compression (VC5 Standard)
Sadly none of the FOSS I tested supports this formats. Now I started to report issues to the different Projects.
Track the progress.
Show other user where they can report issues to get support for new raw formats.
Get information/tips what else I can do.

Hello,
It would be great if Rawtherapee could open .GPR files, a native RAW for… mat provided by the latest GoPro (Hero5).
According to the user manual it is based on the .DNG file format.
I can provides files and help debugging.

Update:
I’ve now installed “Adobe DNG Converter 9.8” with Wine (1.8.5) and it works fine to convert the GoPro GPR files to DNGs. Now I’m able to open this DNG file in darktable, but the files are upside down in darktable 2.2.1. I wrote a bugreport:
opened 07:55AM - 05 Feb 17 UTC

I converted a GoPro .gpr image with Adobe DNG Converter 9.8 to a .dng file. The … files are upside down in darktable 2.2.1.

As github doesn't support uploading dng files I used filebin. The files will expire automatically 2 months from now. Please ping me if it is expired and you need it again.

Now it should be much easier to develop support for the GoPro file format.

Short update. Stloeffler wrote a path for rawspeed, the library that darktable uses, and made a pull request. Now @LebedevRI is reviewing this patch:https://github.com/darktable-org/rawspeed/pull/146

@LebedevRI was reviewing wrong? Whatever you do, I trust on you, that the code will improve.
