The timestampOffset property of the SourceBuffer interface controls the offset applied to timestamps inside media segments that are appended to the SourceBuffer.
The trackDefaults property of the SourceBuffer interface specifies the default values to use if kind, label, and/or language information is not available in the initialization segment of the media to be appended to the SourceBuffer.
The updating read-only property of the SourceBuffer interface indicates whether the SourceBuffer is currently being updated — i.e. whether an SourceBuffer.appendBuffer()SourceBuffer.appendStream(), or SourceBuffer.remove() operation is currently in progress.
The videoTracks read-only property of the SourceBuffer interface returns a list of the video tracks currently contained inside the SourceBuffer.
The length read-only property of the SourceBufferList interface returns the number of SourceBuffer objects in the list.
The SourceBuffer() getter method of the SourceBufferList interface allows the SourceBuffer objects in the list to be accessed with an array operator (i.e. [].)
The TimeRanges.length read-only property returns the number of ranges in the object.
The byteStreamTrackID read-only property of the TrackDefault interface returns the ID of the specific track that the SourceBuffer should apply to.
The kinds read-only property of the TrackDefault interface returns default kinds for an associated SourceBuffer to use when an initialization segment does not contain label information for a new track.
The label read-only property of the TrackDefault interface returns the default label for an associated SourceBuffer to use when an initialization segment does not contain label information for a new track.
The language read-only property of the TrackDefault interface returns a default language for an associated SourceBuffer to use when an initialization segment does not contain language information for a new track.
The TrackDefault() constructor of the TrackDefault interface constructs and returns a new TrackDefault object.
The type read-only property of the TrackDefault interface returns the type of track that this SourceBuffer's media segment data relates to (i.e. audio, video, or text track.)
The length read-only property of the TrackDefaultList interface returns the number of TrackDefault objects in the list.
The TrackDefault() getter method of the TrackDefaultList interface allows the TrackDefault objects in the list to be accessed with an array operator (i.e. [].)
The TrackDefaultList() constructor of the TrackDefaultList interface constructs and returns a new TrackDefaultList object.
