HEIC to JPG conversion fails with Error while loading plugin: No decoding plugin installed for this compression format

[mig5]

Hi,

I am struggling to convert a HEIC file to JPG using your tool

$ magick IMG_5348.HEIC IMG_5348.jpg
magick: Error while loading plugin: No decoding plugin installed for this compression format (11.6003) `IMG_5348.HEIC' @ error/heic.c/IsHEIFSuccess/141

Do you have any idea?

I found https://github.com/strukturag/libheif/issues/1250 which suggests to not compile as separate plugins. I tried that but it still didn't help.

I am calling the script like so, on an Ubuntu 20.04 64-bit machine:

./imei.sh --skip-jxl --force --libheif-version=1.17.6

Attaching log file too imei-1724201043.log

See https://github.com/SoftCreatR/imei/issues/117

Yeah, I did see that, and that's why I'm calling --libheif-version=1.17.6.

I think the version 1.17.6 cmake preset for 'release' does not include the jpeg decoder/encoder plugins, perhaps. Still looking into it.

OK, so yeah, my problem is the reverse: installing with the latest libheif version 1.18.2 is perfectly fine.

I don't need AVIF, so I presumably don't need to downgrade to that 1.17.6 at all, and in fact, that version does not work for me to convert HEIC to JPG.

Closing this out.
