As I needed this myself, I implemented a basic GPR decompressor in #146 - I hope this helps.

GoPro HERO5 Black RawTherapee issue:
Beep6581/RawTherapee#3569

from rawspeed.

https://trac.ffmpeg.org/ticket/1087

https://git.ffmpeg.org/gitweb/ffmpeg.git/blob_plain/HEAD:/libavcodec/cfhd.c <-- that is supposed to decode the video, so the compression might serve as a template?

This codec goes by VC-5 (misnamed, it seems), cfhd, CineForm HD.

Yep, seen that yesterday.
I suppose libraw will want to link to that.
As for rawspeed, i suppose a clean, minimal implementation (with less horrible code than that, and no double/triple-licensing shenanigans) could be added by implementing from scratch.

I suppose libraw will want to link to that.

Most likely no in (coming) 0.19, but most likely yes in next version cycle

GoPro just released the HERO7, are there any news here ore in @LibRaw?

from rawspeed.

Here - no, nothing has changed.

After reading through the existing crumbs of info on the Canon's CRX codec,
they both seem to be based on wavelets, which is, i suppose, not all that surprising.
So maybe after Canon's CRX codec is implemented,
maybe this could be implemented on top of that code.

Btw. I just discovered this project:
