heif_decode_image() reports error "Unsupported feature: Unsupported codec" #868

HI, I installed GraphicsMagick that supports libheif

GraphicsMagick: 1.3.40
libheif: 1.16.1

It seems that the installation is successful, but some commands do not support it. Is this normal?

Thanks

GraphicsMagic (and many other users) only include AVIF support by default, HEIC is encumbered by an obnoxious number of patents by very litigious companies. You have to build it yourself to get that support, via de265 and x265.

It might be worth saying that HEVC/H.265 support has been excluded, since it's such a common case for open source repositories.

Can I ask why this is reported against libheif, rather than against GraphicsMagick? Did they suggest it was an upstream issue?

I'm not entirely sure whether it's GraphicsMagick's problem or libheif's problem, but the error message points to the decode part of libheif.

it executed successfully, And I think this may not be an issue with the image itself. Thanks.

So if heif-convert worked, and you still have problems with GM, you must have more than one libheif installed, or GM is doing something a bit strange .

LvChenhui commented 1 year ago

I found a command with an error, which also looks like a decoding issue.

$heif-info avif.jpg

bradh commented 1 year ago

That appears to be a different problem since it is about avif not heif. You might want to create a distinct issue and attach the file. Or since your earlier reports did not show an AVIF decoder (just de265), maybe you should fix your configuration first.

oh...It was my mistake, and I was able to handle the HEIF image successfully.

heif-info heic.jpg

I'm sure only one libheif was installed. In the version of gm that does not support libheif, running the command gm identify img.heif will lead to an error. However, in our current version, it can return results as expected, as previously mentioned. But when running -verbose to get more information, errors may occur.

Thank you for your continuous help~

bradh commented 1 year ago

I still don't think that this is a libheif problem, since the libheif tools work as expected.

I am confused by the discussion of various versions of GM, which you probably need to work though (e.g., with ldd) to figure out what is happening.

bradh commented 1 year ago

@LvChenhui were you able to resolve your issue? If not, can you add more details that would allow your issue to be reproduced?
