Bug 63202 – webkitEnterFullscreen should not require user gesture if mediaPlaybackRequiresUserAction is false

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Media

[Adam]

Calling .webkitEnterFullscreen() will raise INVALID_STATE_ERR except from a user-initiated gesture. If document()->settings()->mediaPlaybackRequiresUserAction() is false, I believe webkitEnterFullscreen should be allowed without a user gesture.

The machinery behind the gesture requirement for webkitEnterFullscreen is roughly the same as that behind the load() and play() restrictions requiring a user-initiated gesture. The mediaPlaybackRequiresUserAction property was added for the express purpose of letting users disable these restrictions (which we do in our iOS app's UIWebView).

mediaPlaybackRequiresUserAction is mapped into a corresponding "BehaviorRestrictionFlag" on HTMLMediaElement. (See WebCore sources/html/HTMLMediaElement.h.) This is checked in play() and load().

Adapting webkitEnterFullscreen accordingly would be a relatively small change: a new BehaviorRestrictionFlag set accordingly and updating HTMLVideoElement::webkitEnterFullscreen to check it.
