1727105 - Images do not load with image.avif.enabled=true

Status: RESOLVED DUPLICATE of bug 1727033

(Core :: Graphics: ImageLib, defect)

Description

[Ksenia Berezina [:ksenia]]

We've got reports about missing images on two websites:

1. https://www.oantagonista.com/ (Example image: https://cdn.oantagonista.com/cdn-cgi/image/fit=contain,width=340,format=auto/uploads/2021/08/joao-doria-23.ago_.2021-2.png)

2. https://www.notion.so/ (Example image: https://notion.so/cdn-cgi/image/f=auto,w=3840,q=100/front-static/shared/illustrations/templates.png)

Images load when setting image.avif.compliance_strictness to 0.

This doesn't seem to be related to https://bugzilla.mozilla.org/show_bug.cgi?id=1725022 (different errors in AOM AVIF validator).

Hi Jon, this looks like another case of invalid AVIF. Would you be able to take a look, please?

There is one more report with the following image https://img.cdn4dd.com/cdn-cgi/image/format=avif,width=100/https://cdn.doordash.com/media/photos/65314aee-a40e-4784-a335-232accd30349-retina-large.jpg:

AVIF parser in Firefox 92 is more strict than in Chrome. All AVIF files generated by Cloudflare (all sites using Cloudflare image optimization) are broken in Firefox, but work fine in Chrome 92.

Assuming these are from the Cloudflare CDN, the issue is bug 1727033, but it could also be another source using the same AVIF writer as described in bug 1727106 (or possibly a different writer which generates similarly malformed AVIF files). Considering Cloudflare to be the most likely source, I'll dupe it to bug 1727033.

Thanks! Indeed, looks like all images are from the Cloudflare CDN
