Converting HEIC to PNG requires global libvips #3816

Closed blok5025 closed 1 year ago

blok5025 commented 1 year ago

Possible bug

When doing: const data = await sharp(input) .png() .toBuffer(); On a HEIF type of file,

I get: "heif: Unsupported feature: Unsupported codec (4.3000)]"

Is this a possible bug in a feature of sharp, unrelated to installation?

Are you using the latest version of sharp?

Is the HEIF file using AV1 (AVIF) or HEVC (HEIC) compression? Did you see https://sharp.pixelplumbing.com/api-output#heif ?

Support for patent-encumbered HEIC images using hevc compression requires the use of a globally-installed libvips compiled with support for libheif, libde265 and x265.

Yes I am using HEIC as the input. Do you have any instructions for installing libvips globally and getting the conversion to work?

I doubt this can work inside of a Google Cloud Function. I couldn't find any ways of using Meson inside of Google Cloud to install dependencies.

Unless you know any workarounds?

Waiting for the HEVC patents to expire (c2036) will probably take less time. Good luck!

@lovell I'm a bit confused, so what exactly do we do to solve this issue?

I'm uploading images from my iPhone and trying to resize them to create thumbnails.

If you're dealing with patent-encumbered HEVC-compressed HEIC files and use a third-party runtime environment over which you have limited control then sharp is probably the wrong solution to your problem.
