File Format #1

Closed AKSoapy29 closed 6 years ago

AKSoapy29 commented 7 years ago

Hi. What file formats does your app support? I was looking through the app code to see if I could figure it out and expand it to Sony's ARW format. Maybe I have the NextCloud environment setup wrong?

ariselseng commented 7 years ago

@AKSoapy29 I have not tried ARW. If exiftool can extract a preview image then it should work. Provided that the reported mimetype by nextcloud is "image/x-dcraw". Have you had success with a normal CR2 file?

Try this as a first test:


$ exiftool -b -PreviewImage test.arw > preview.jpg
ariselseng commented 7 years ago

Oops, I accidently closed this issue. That was not my intention.

@AKSoapy29 If that command fails. You can try this one too:


$ exiftool -b -ThumbnailImage test.arw > preview.jpg
AKSoapy29 commented 7 years ago

I tried -PreviewImage, and that worked. I did not try -ThumbnailImage. I found a CR2 file online to test with, and it doesn't look like it generates a thumbnail in NextCloud. The 'camerarawpreviews' folder just goes in the 'apps' directory, correct? I don't think NextCloud is recognizing it.

ariselseng commented 7 years ago

Yes, correct. You put it in the apps/ folder. And then you need to add the configuration as mentioned in readme.md. After that you can enable the app in the app list in nextcloud.

It also may very well be that you need to add the proper mimetypes (see official admin documentation for that) to your nextcloud installation, but I am not totally sure.

AKSoapy29 commented 7 years ago

I checked in the app list after I installed it, but I didn't see anything. Could permissions on the files / directory effect something?

ariselseng commented 7 years ago

Maybe. Make the files is owned by the same user that php runs as and it should be ok. What version of nextcloud are you running?

The latest: 11.0.2.

ariselseng commented 7 years ago

I would try to install other apps the same way to determine if there is anything specific with my app or not.

Well I'm obviously doing something wrong, but I don't know what :/ I can't get a different app working either. I tried Theme Switcher: https://apps.owncloud.com/content/show.php/Theme+Switcher?content=173857

bspradling commented 6 years ago

I'm kind of running into this same issue. I'm looking to get ARW images working but after installing. I can see CameraRawPreviews in the app list, however, the Enable button is greyed out and there is another button next to it wanting me to remove the application. Do you know of a way to get it enabled?

ariselseng commented 6 years ago

What version do you have? Maybe you can try to enable it with occ command? Maybe you get an error message that you can look up. Also check the nextcloud log for any thing related.

Do you have all the requirements for the app? Like exiftool, adding the needed config. Correct mimetype mappings for your format. Also, I am not sure if ARW works right yet.

stowel commented 6 years ago

@bspradling8 Did you tried to enable the app with occ command?

  1. Switch to nc install dir
  2. run: sudo -u www-data php occ app:enable camerarawpreviews

I've enabled camerapreview like this, installed exiftool, ImageMagick and Magick-Php5, added following lines to my config.php ... 'preview_max_filesize_image' => 500, 'enabledPreviewProviders' => array ( 0 => 'OC\\Preview\\Image', 1 => 'OC\\Preview\\MP3', 2 => 'OC\\Preview\\TXT', 3 => 'OC\\Preview\\MarkDown', 4 => 'OC\\Preview\\Epub', 5 => 'OC\\Preview\\FB2', 6 => 'OC\\Preview\\PDF', 7 => 'OCA\\CameraRawPreviews\\RawPreview', 8 => 'OCA\\CameraRawPreviews\\IndesignPreview' ), ... JPG, PNG, TIFF Preview is working, but with raw files (DNG, CR2) I get the error:

Error! Preview can't generate file....

and in nextcloud.log:

.... "app":"gallery","method":"GET","url":"\/apps\/gallery\/preview\/312900?width=2000&height=2000&c=7aed1484dda22268b86d6bb6afec2b24&requesttoken=xljm236xHJuIsrPDW2PxfqcGYh6oK5S4XFFz0bH%2BOAU%3D%3ArQHW8FGCVd%2Fi1oexHiSDEssyAEaeBN7pOhcEuIbVQEk%3D","message":"Exception: Preview generation has failed" ....

ariselseng commented 6 years ago

I should find some time to write a good how to. I think the thing you are missing now is correct mimetypes. But not really sure about that.

What mimetypes should I change/add?

In ./resources/config/mimetypemapping.dist.json both formats are already present:

...
"dng": ["image/x-dcraw"],
"cr2": ["image/x-dcraw"],
...
ariselseng commented 6 years ago

That is the correct ones. How much memory do you allow php?

I've set no memory limit (value -1), the server got around 10GB free RAM. ...

php.ini: .... ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = -1 ...

ariselseng commented 6 years ago

@stowel What happens when you see the file in the files app? Do you get a preview or an attempt at an loading preview at all?

stowel commented 6 years ago

After I tried to update mimetype.js with:

php occ maintenance:mimetype:update-js

nc is not showing the preview plugin anymore and starts downloading cr2 and dng files directly. Before that the preview plugin loads and shows a black screen with the message

Error! Preview can't generate file....

Looks like it getting even worse... :-(

ariselseng commented 6 years ago

I think you can see the mimetype of the file by checking with webdav output.

bspradling commented 6 years ago

Sorry I'm late getting back to this. I was finally able to run the occ command to try and enable CameraRawPreviews. I get back the following: [Exception] App "CameraRawPreviews" cannot be installed because it is not compatible with this version of the server.

I'm running the latest via Docker. @cowai What version does CameraRawPreviews support?

ariselseng commented 6 years ago

Right now 13 is specified in appinfo. Did you get it working? @bspradling8

ariselseng commented 6 years ago

No answer. Please reopen if the issue is not resolved.
