The average bitrate in bits per second, or -1 if unknown or not applicable. The way in which this field is populated depends on the type of media to which the format corresponds:

• DASH representations: Always -1.
• HLS variants: The AVERAGE-BANDWIDTH attribute defined on the corresponding EXT-X-STREAM-INF tag in the multivariant playlist, or -1 if not present.
• SmoothStreaming track elements: The Bitrate attribute defined on the corresponding TrackElement in the manifest, or -1 if not present.
• Progressive container formats: Often -1, but may be populated with the average bitrate of the container if known.
