Nextcloud 20 help with HEIC support via Imagick7

[TomComm]

I found the fault on my own.
After trying more and more, I found out that harfbuzz-3.0.0 was installed and that it was not up-to-date, even though I had previously run the command pkg install harfbuzz.
A manual deinstallation of harfbuzz-3.0.0 and then an installation with the command pkg install harfbuzz helped.

The error no longer occurred and I finally got HEIC running as a preview.

Excellent, thank you for the great guide! This worked like a charm after spending a couple of nights awake looking for workarounds.

Hello! I have been following a few guides for the past week or so getting Nextcloud up and running and have been successful on everything EXCEPT for HEIC support. I've followed the guide here and when I run "convert -list format | grep HEIC" it lists a few items - and everywhere I've looked this apparently means HEIC is enabled...but it still doesn't work. Does anyone have any suggestions on where to look? Thanks!

I've compiled HEIC support in PHP before using the same method mentioned here, however now I don't get HEIC support in PHP for some reason.
I even took it one step further and compiled the imagemagick module for PHP, so all versions match now. The only thing that got HEIC support is convert:
Version: ImageMagick 7.1.0-34 Q16-HDRI amd64 20058 https://imagemagick.org

PHP ImageMagick:

Imagick compiled with ImageMagick version	ImageMagick 7.1.0-34 Q16-HDRI amd64 20058 https://imagemagick.org
Imagick using ImageMagick library version	ImageMagick 7.1.0-34 Q16-HDRI amd64 20058 https://imagemagick.org

But HEIC isn't listed under ImageMagick supported formats

I fixed the above issue. Apparently libheic was too old (?) because I had locked the package. I unlocked it and ran pkg update and pkg upgrade then it started to work after I restarted php-fpm.
