Bug 256848

Created attachment 466363 [details] Drawn gradient frame with packed (16 stride) and extra bytes (32 stride) on 16x16 input, as seen in Safari 16.4 When creating a VideoFrame from an ArrayBuffer, if the codedWidth is wider than the provided visibleWidth, the resulting frame is corrupted in Safari, while it works as expected in Chrome. Here's a sample jsfiddle which works as expected in Chrome on my M1 MacBook Air but fails in Safari on the M1 MacBook Air, iPhone 13, and i9 MacBook Pro: https://jsfiddle.net/1tf8g04c/ I've worked around it in my case by simply producing packed frames that don't need a larger codedWidth, but this may not always be convenient.
