- Active cues now returns the subset of cues in mCueList that are valid
for the current playback time.
- Introduces new code in media element, when seeking, and in TextTrack, when
adding and removing cues, to mark the active cue list as dirty so that we know
when we might need to rebuild the list completely.
- We expect most files to already be sorted, so an insertion sort starting from
the end of the current array should be more efficient than a general sort step
after all cues are loaded
- Added a test for insertion sorting as well.
- Updated RemoveCue to throw NotFoundError if the cue being removed is
not in the cue list.
- Updated AddCue to not add cues that are already in the list. This is
done by reference comparing.
- Implemented WebVTTLoadListener to manage the webvtt parser.
- TextTrackCue now handles the conversion of webvtt nodes to
anonymous content which will be displayed on the video div
overlay.
- HTMLTrackElement manages the lifetime of the WebVTTLoadListener.
Add webidl interfaces and implementations of the HTML <track>
element and related TextTrack, TextTrackList, TextTrackCue,
and TextTrackCueList dom objects.
Visibility is controlled by the media.webvtt.enabled pref,
which defaults to false.
HTMLMediaElement:NewURIFromString() is hoisted to
nsGenericHTMLElement so it's available to the track
element as well.
This patch is primarily work by Dale Karp, David Humphrey
and others as Seneca College.
