Adaptive Bitrate API

'performance': The player will optimize ABR behavior to focus on the performance of the player. This strategy initiates playback with the lowest quality suitable for the device which means faster start-up time.
'quality': The player will optimize ABR behavior to focus on displaying the best visual quality to the end-user. This strategy initiates playback with the highest bit rate suitable for the device.
'bandwidth': This is the default strategy. The player will optimize ABR behavior to focus on displaying the most optimal quality based on historic bandwidth data and knowledge of the network conditions. When no historic data is available, the player will use the performance strategy.

Adaptive Bitrate (ABR) API

The Abr object allows to control the adaptive bitrate behavior of the player. This API is available from version 2.30.0 onward.

The Abr object provides the following properties:

Property	Type	Description
strategy	ABRStrategyConfiguration	Optionally specifies one of the available pre-set strategies that the player will use. The following strategies are available 'performance' : The player will optimize ABR behavior to focus on the performance of the player. This strategy initiates playback with the lowest quality suitable for the device which means faster start-up time. 'quality' : The player will optimize ABR behavior to focus on displaying the best visual quality to the end-user. This strategy initiates playback with the highest bit rate suitable for the device. 'bandwidth' : This is the default strategy. The player will optimize ABR behavior to focus on displaying the most optimal quality based on historic bandwidth data and knowledge of the network conditions. When no historic data is available, the player will use the performance strategy.
targetBuffer	number	Allows for configuring the amount of seconds to buffer ahead of the current playback position. The player might sometimes buffer less than the configured amount because of device or performance constraints.

An object specifying strategy and metadata that the player will use for initial playback.

Property	Type	Optional	Description
type	string	yes	Type of strategy.
metadata	Bitrate	yes	Specifies metadata required to start playback

An object specifying a bitrate that can be used to select the optimal quality.

Property	Type	Optional	Description
bitrate	number	yes	A bitrate measuring in bits per second, used for initial playback
