Hello @yanxianrui,

It's working for me:

john@yingna ~/pics $ vips copy 1.jpg 1-80.heif[strip,Q=80]
john@yingna ~/pics $ vipsthumbnail 1-80.heif
john@yingna ~/pics $ 

libheif 1.6.1
libvips 8.11
x265 3.2.1
libde265 1.0.4
ubuntu 20.04

I'm not sure which of your packages you need to update though. Did you mean libvips 8.11? Your ubuntu sounds too old as well. Your x265 seems very old too.

Here's the 1-80.heif that I made:

1-80.heif.zip

If you can vipsthumbnail that I guess the problem must be in your x265.

[yanxianrui]

sorry it's vips 8.10.2 and thank you for your prompt reply.
I've tried x265 3.3 before but it doesn't work.
I‘II update all my packages to your version to try except my old ubuntu. 😭 I must use it.

I think this is a duplicate of #1808. Since commit strukturag/libheif@c6f7945 (i.e. libheif >= v1.8.0) an odd-sized HEIF file is written with a clap box to crop away the padding border. However, this causes problems when libvips tries to load such images, as it requires that the frame size corresponds with the size specified in the container.

A similar issue can be observed with Google Chrome and libheif-encoded AVIF images smaller than 16×16 pixels (only when libheif is built with aom).

[jcupitt]

Ah, I understand! Sorry Kleis, I've not been following that issue.

I suppose libvips needs a patch for this change?

[kleisauke]

Probably some additional clipping code needs to be added.

Hello @jcupitt
I can vipsthumbnail the heif file you made. And no error occurs when I try to use libheif 1.6.1.
thanks a lot for your reply and info.
should I close this question or wait for a patch ?

@jcupitt dunno if it's related but I'm getting a: source: bad seek to 1272289 when loading the following heic file: IMG_2631.HEIC.

It's from "the wild" so I have no clue how it was created/saved.

I'm using a custom build with:

• libde265 1.0.8
• libheif 1.9.1
• libvips 8.10.2
• x265 3.4

I cannot seem to find libvips 8.11 and I'm unable to test with it, was it released some place else than github?

[jcupitt]

Hi @jaubourg, that looks like a different issue. I tried with git master libheif and their heif-convert example reads your file correctly, but libvips fails.

Could you open a new issue please?

[jaubourg]

@jcupitt done! ;)
