            Bug ID: 230617
           Summary: gl.texImage2D upload of getUserMedia streams via
                    <video> element fails on iOS 15.1 beta 1
           Product: WebKit
           Version: Other
          Hardware: iPhone / iPad
                OS: Other
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: WebGL

Uploading a camera stream to a WebGL texture using getUserMedia(...), a <video> element, and gl.texImage2D(...) is failing in Safari on the iOS 15.1 beta 1 release.

It works correctly on the release version of iOS 15.0 and earlier.

I've prepared a minimal test case here:

The page should show a live camera feed in the canvas after allowing camera permissions. On iOS 15.1 beta 1 no camera feed appears. The source for this test case is entirely within the page itself should you wish to take a look at how it's implemented.

This is a common flow for web-based augmented reality and image processing applications. We have many sites and customers who rely on this behaviour to work correctly, so this is a major regression and concern for us.

The same issue is also reported in the following bug but I've filed this one with a minimal test case and a more specific title in the hopes that it helps surface this significant regression to the right team :-)

Let me know if I can help with any questions!
