Thumbs generate but previews don't

[D34DC3N73R]

I see thumbnails generated, but previews fail to load. These are ARW's from a sony camera.

@D34DC3N73R Are you sure there is preview information in your file? This app only extracts the jpeg already inside the file.

@D34DC3N73R Also, you could send me a sample file that has this issue and I could see if I can reproduce your issue.

[D34DC3N73R]

I sent a sample to your email. I'm sure it used to work because I've previously previewed ARW files from the same camera. Unfortunately, I don't know the exact version it stopped working. Thanks for taking a look!

Hi, I'm having the same problem but with opening NEF files.
Camera RAW Previews version is 0.8.0
I'm running NextCloud 25.0.1 from TrueNAS.

Same as above, a thumbnail is created, but when I open a NEF file itself there's an infinite spinner. The image that I'm trying to open is 24 MB

Here's a small file example that doesn't work
infrared.nef.zip

I'm curious to know about the fix

[D34DC3N73R]

I've updated to Nextcloud 24.0.7 and still have the same issue, with CRP v0.8.0. I haven't found a solution yet.

another strange thing that I noticed:
Opening a NEF file directly doesn't work (infinite spinner), but switching to next/previous and going back does result in a working preview.

I have the same problem with Olympus RAWs. And I confirm the forward/back operation that @andreybavt comments.

I am pretty sure this is a regression in the viewer app. Does anyone care to downgrade the viewer app to a known good time/version?
As long as the this app provides previews to nextcloud, it is up to the individual app to use it correctly.

I just tested several versions of the viewer app and the last good version of the v24 branch is 24.0.3. I only tested 25.0.1 of the v25 branch, but I guess all versions of the v25 branch are broken.

Thank you. I would appreciate if you or somebody else could open an issue at the viewer repo.

Since there haven't been many changes between 24.0.3 and 24.0.4, I'm pretty sure that this commit broke the file handler logic:

@andreybavt has already created an issue: nextcloud/viewer#1450
