Here is an example of an issue with quicktime movie captured from an iPhone while rotated 180° will be corrected in the video element, however when trying to drawImage to canvas, only the currentTime = 0 will ever be drawn. See this example: https://codepen.io/jordanaustin/pen/VwYzmGw Capture image, then seek past currentTime = 0 and you'll still only get the image from the video elements first frame.

Is there anything else I can provide that would be useful for triaging this bug? This is a pretty serious issue that is exclusive to Webkit.

Does this affect a current website or app, or one that's currently being built? If so, that info would help prioritize.

Yes, one of our products videoanalysis.app is a web application that allows science students to analyze motion of real world objects in videos. This is Vernier's web application counter part to Vernier Video Physics (https://apps.apple.com/us/app/vernier-video-physics/id389784247) This bug causes problems for nearly every Safari user, forcing us to employ complex work arounds, including WASM moduals that transcode or teansmux every video in Safari
