Support preview images for heic

[jameskimmel]

Currently it downloads the image, viewing a preview it in the browser would be nice.
Most modern smartphones take pictures in heic.
Since heic unfortunately isn't supported on most browsers, the preview image would probably need to be JPG?

Technically very easy, can be done with a one line change in our thumbnailer.

BUT: Decoding Heic images on the server is currently protected by patent.

That is a shame. So basically it will never be implemented?
Sorry for the stupid question, but why or how was it possibe for Nextcloud to implement it?
They seem to use imaginary for it

Users can decide to load extensions on their system which are not shipped by the software vendor and then the responsability is shifted to the admin.

Golang is a compiled language and we would need to compile that in. We could think about using imagick which shifts the problem to the admin.

Thank you for the detailed reply.
I know stuff like this is annoying, but it is extremely important for the end user.

A stupid user like me does not care about licenses and stuff. I see that OneDrive, Google Photos, iCloud Photos, Dropbox, GDrive all support it. If I create a public folder for friends to drop in our pictures of our holidays together, I simply expect it to work like every other service listed. And this is not only related to private stuff, also at work, if I share a picture of a construction site with someone external, I simply expect it to be working.

Stuff like this sometimes gets overlooked in OSS.
But it is simply stuff like that which can make the difference between usable and not usable for the user.
What I am trying to say with way too many words is that the importance of this feature cannot be understated :)

If that means the admin has to configure imagick (Nextcloud does not enable it by default for imagick, apparently some security flaw) that is totally fine.

sorry, did not realize that this project uses issues for feature requests and only searched here. Will copy paste it to that issue.
