            Bug ID: 172675
           Summary: Setting 'Video Needs User Action' still applies after
                    user media access has been granted
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media Elements
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: andrew at tokbox.com

My understanding is that 'Video Needs User Action' should not apply when user media access has been granted, but it does. I get a NotAllowedError. Interestingly though, after delay(0).then(play) (based on setTimeout), it works. Perhaps user media access is indeed unblocking it but the promise is fulfilled with the stream before the unblock occurs.

This jsbin takes the following queryString parameters:

userAction    - Play video on user action (uses click event by default)
videoFromFile - Play an mp4 file in the video element instead of a user media stream
delay         - Play video after specified milliseconds (0 by default)

Examples:
?                                    - Play user media without delay
?delay                               - Play user media with 0ms delay
?videoFromFile&delay                 - Play a file after 0ms delay
?userAction=click&videoFromFile      - Play a file on click event
?userAction=touchstart&videoFromFile - Play a file on touchstart event
