heif: Error while loading plugin: No decoding plugin installed for this compression format about sharp

[lovell]

I suppose sharp is not correctly building from source and does not use the globally installed libraries. How can I verify/debug this?

All decisions are logged at install time. You might need to add the npm install --foreground-scripts flag to display them.

installed libvips on OSX

What is the output of running vips copy input.heic output.png at the command line for your sample input image?

I have the same problem but with jpeg (tried png also to match above issue).

Running vips on the command line works for both png and jpeg for me.

Experiencing the same as above, just on a Linux container environment.

vips copy works fine, but I get a seeking error like the OP.

Please remember that reading HEIC images requires sharp to be built from source against a globally-installed libvips + libheif + libde265 combo - see https://sharp.pixelplumbing.com/install#building-from-source

For those using a custom, globally-installed libheif, my best guess would be that this relates to its plugin system, which can be switched off at compile time using the -DENABLE_PLUGIN_LOADING flag (set it to one of 0, NO or OFF) as others have been directed to do at strukturag/libheif#1250

I have the same problem, using an ubuntu-based container that should contain all the required libraries.
This is the relevant snippet from my dockerfile:

RUN apt update && apt install -y libvips-dev libheif-dev
ENV SHARP_FORCE_GLOBAL_LIBVIPS=1

Using heif-convert from the heif-examples package works fine.
heif-convert --list-decoders output:

HEIC decoders:
- libde265 = libde265 HEVC decoder, version 1.0.15
AVIF decoders:
- aom = AOMedia Project AV1 Decoder v3.8.2
JPEG decoders:
JPEG 2000 decoders:
uncompressed: yes

I suppose sharp is not correctly building from source and does not use the globally installed libraries. How can I verify/debug this?

Thank you for the hint.
This revealed that the ubuntu packaged libvips has a version-mismatch with the latest version of sharp and is thus not building correctly.
Building the correct versions of the libraries should resolve the issue for me.

I hope this information helped. Please feel free to re-open with more details if further assistance is required.
