<pre>[iOS Media] Video buffer progress missing on iPhones
https://bugs.webkit.org/show_bug.cgi?id=142462
Reviewed by Eric Carlson.
Source/WebCore:
The fullscreen controller on the iPhone idiom was using
the media duration as its maximum loaded time, meaning the
download progress was missing (it looked like everything
was already downloaded). The fix is to calculate
what the maximum buffered time is from the HTMLMediaElement,
and send that to the fullscreen controller.
* Modules/mediacontrols/mediaControlsiOS.js:
(ControllerIOS.prototype.drawTimelineBackground): While implementing
the native function I noticed that the JS controls forgot that
the buffered time ranges are ordered, and thus they don't need
to search through the array. The last range will be the highest.
* html/HTMLMediaElement.cpp:
(WebCore::HTMLMediaElement::maxBufferedTime): New helper function
to calculate the highest buffered time in the media source.
* html/HTMLMediaElement.h:
* platform/ios/WebVideoFullscreenInterface.h: New setBufferedTime method.
* platform/ios/WebVideoFullscreenInterfaceAVKit.h:
* platform/ios/WebVideoFullscreenInterfaceAVKit.mm:
(WebVideoFullscreenInterfaceAVKit::setDuration): No longer set
the loadedTimeRanges.
(WebVideoFullscreenInterfaceAVKit::setBufferedTime): Calculate a normalized
value of the maximum loaded/buffered time, and tell the platform controller
to show that range.
* platform/ios/WebVideoFullscreenModelVideoElement.mm:
(WebVideoFullscreenModelVideoElement::updateForEventName): Send the maximum
buffered time.
Source/WebKit2:
Coordinate the SetBufferedTime message between the Web and UI
processes.
* UIProcess/ios/WebVideoFullscreenManagerProxy.messages.in: New message SetBufferedTime.
* WebProcess/ios/WebVideoFullscreenManager.h:
* WebProcess/ios/WebVideoFullscreenManager.mm:
(WebKit::WebVideoFullscreenManager::setBufferedTime):</pre>
