            Bug ID: 228997
           Summary: First frame of MSE video obtained through drawImage or
                    texImage2D is empty
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: kkinnunen at apple.com

First frame of MSE video obtained through drawImage or texImage2D is empty

When JS obtains the video frame, the MSE implementation switches decoding from "layer" to "decoder session". This loses the current frame.

Affected bug 228821 where texImage2D-mse-flipY-true.html would print errors to console for the first frame upload.
