The abort() method of the SourceBuffer interface aborts the current segment and resets the segment parser.

The appendBuffer() method of the SourceBuffer interface appends media segment data from an ArrayBuffer or ArrayBufferView object to the SourceBuffer.

The appendStream() method of the SourceBuffer interface appends media segment data from a ReadableStream object to the SourceBuffer.

The appendWindowStart property of the SourceBuffer interface controls the timestamp for the start of the append window, a timestamp range that can be used to filter what media data is appended to the SourceBuffer. Coded media frames with timestamps wthin this range will be appended, whereas those outside the range will be filtered out.

The audioTracks read-only property of the SourceBuffer interface returns a list of the audio tracks currently contained inside the SourceBuffer.

The buffered read-only property of the SourceBuffer interface returns the time ranges that are currently buffered in the SourceBuffer.

The remove() method of the SourceBuffer interface removes media segments within a specific time range from the SourceBuffer.

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 length read-only property of the SourceBufferList interface returns the number of SourceBuffer objects in the list.

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.
