<h3>Log Message</h3>
<pre>HTMLMediaElement::isPlayingAudio() should return false if the element is explicitly muted by script.
https://bugs.webkit.org/show_bug.cgi?id=140524
Reviewed by Andreas Kling.
Source/WebCore:
Test: media/muted-video-is-playing-audio.html
* html/HTMLMediaElement.cpp:
(WebCore::HTMLMediaElement::setMuted):
Call Document::updateIsPlayingAudio() to recalculate the overall audio playing state.
(WebCore::HTMLMediaElement::isPlayingAudio):
HTMLMediaElement::isPlayingAudio() should return false if the media element is explicitly muted.
LayoutTests:
The test contains a looping video. It makes sure initially Page::isPlayingAudio() returns true.
It should return false after the video is muted, and true again after the video is unmuted.
* media/muted-video-is-playing-audio-expected.txt: Added.
* media/muted-video-is-playing-audio.html: Added.</pre>
