            Bug ID: 248249
           Summary: Some valid JP2s are failing to decode
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: e at ericportis.com
                CC: sabouhallawa at apple.com

This valid JPEG2000 file does not decode in Safari 16 running on macOS Ventura 13.0.1, MacOS Monterey 12.6, or iOS 16.1.1.

Note:
- Changing the image slightly (resizing by one pixel) causes it to work: https://assets.meinauto.de/image/upload/f_jp2,w_3248/v1668594966/website/pics/landingpages/black-deals/red
- This bug seems *very* related to FB9671920 / https://bugs.webkit.org/show_bug.cgi?id=219977

I have cross-filed this as FB11815925, and fully expect this WebKit bug to be closed as RESOLVED INVALID, because the bug is in the media handling layers in the OS. However previous experience has shown it is valuable to have a public URL to reference and share resources/workarounds when others run into this bug in Safari.
