https://www.w3.org/Bugs/Public/show_bug.cgi?id=22143 Bug ID: 22143 Summary: MediaPlaybackQuality interface should limited to HTML5VideoElement Classification: Unclassified Product: HTML WG Version: unspecified Hardware: PC OS: Windows NT Status: NEW Severity: normal Priority: P2 Component: Media Source Extensions Assignee: adrianba@microsoft.com Reporter: jdsmith@microsoft.com QA Contact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-media@w3.org Section 7.2 of the current draft adds MediaPlaybackQuality to the HTMLMediaElement. These can be audio only, in which case the frame quality metrics shouldn't apply. Recommend replacing HTMLMediaElement with HTMLVideoElement in 7.2: 7.2 New Attributes and Behavior This section specifies new attributes and internal state that are being added to the HTMLVideoElement. Each HTMLVideoElement will maintain a total video frame count variable that keeps track of the total number of frames that have been displayed and dropped. This variable is initialized to 0 when the element is created and whenever the media element load algorithm is invoked. It is incremented when a video frame is displayed or when the dropped video frame count is incremented. Each HTMLVideoElement will maintain a dropped video frame count variable that keeps track of the total number of frames that have been dropped. This variable is initialized to 0 when the element is created and whenever the media element load algorithm is invoked. It is incremented when a video frame is dropped predecode or when a frame is decoded but dropped because it missed a display deadline. partial interface HTMLVideoElement{ readonly attribute MediaPlaybackQuality playbackQuality; }; This paragraph is a subparagraph of 7. HTMLMediaElement Extensions, which makes this fit a little awkward. It fully describes the requested change though. -- You are receiving this mail because: You are on the CC list for the bug.
