Interface AudioQuality

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.

The bitrate in bits per second. This is the peak bitrate if known, or else the average bitrate if known, or else -1.

The number of audio channels or -1 if unknown.

The codec of the media quality.

The id of the media quality.

The label of the media quality that should be exposed to the user.

The peak 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: The @bandwidth attribute of the corresponding Representation element in the manifest.
• HLS variants: The BANDWIDTH attribute defined on the corresponding EXT-X-STREAM-INF tag.
• SmoothStreaming track elements: Always -1.
• Progressive container formats: Often -1, but may be populated with the peak bitrate of the container if known.
