What compression mode is the camera set to use? Not all of the newest compression modes are supported....

[ptilopteri]

can you provide a couple of the failing raw files on a file sharing site?

[victoryforce]

Camera is set to compression mode RAW-s (loss free compression)

Such files (downsized lossless ARWs) are not supported. This is clearly written in the release notes (look for the Missing Compression Mode Support section).

[kmilos]

Lossless should be supported since 4.6.1 - L size only though, not M nor S.

[lkarcz]

Lossless should be supported since 4.6.1 - L size only though, not M nor S.

@kmilos aaaaaand... any plans / possible dates for M/S support?

[tdausner]

@victoryforce thank you for clearance.
@other release notes say: "Missing Compression Mode Support -> Sony downsized lossless ARWs ("M" for full-frame, "S" for full-frame & APS-C)"
I'll set my camera to "no compression". The (few) images taken with compression are accepted by darktable after conversion with Adobe DNG converter 😄

Note that you don't have to turn compression completely off, just stick to "L".

@lkarcz I personally have no plans for this. For all I know, maybe you're working on a patch!

I wish I was able to... As for now, GH ticket is all I can make ;)
