Class ABRControlParameters

java.lang.Object
  com.adobe.mediacore.ABRControlParameters

public final class ABRControlParameters
extends Object

Encapsulates all ABR control parameters. Currently supported parameters are: - adaptive bit-rate switch policy - minimum bit-rate - maximum bit-rate - initial bit-rate

Nested Class Summary

static class

ABRControlParameters.ABRPolicy Enumeration for the supported bit-rate switching policies: - ABR_CONSERVATIVE - Starts at lowest BW, steps up automatically when available BW is 50% more than required BW for step-up.

Constructor Summary

ABRControlParameters(int initialBitRate, int minBitRate, int maxBitRate, ABRControlParameters.ABRPolicy abrPolicy)
Constructor method.

Method Summary

ABRControlParameters.ABRPolicy	getABRPolicy() Getter method: returns the value of the initial bit-rate control parameter.
int	getInitialBitRate() Getter method: returns the value of the initial bit-rate control parameter.
int	getMaxBitRate() Getter method: returns the value of the maximum bit-rate control parameter.
int	getMinBitRate() Getter method: returns the value of the minimum bit-rate control parameter.

Constructor Detail

ABRControlParameters

public ABRControlParameters(int initialBitRate,
                            int minBitRate,
                            int maxBitRate,
                            ABRControlParameters.ABRPolicy abrPolicy)

Constructor method. Sets the values for the ABR control parameters. NOTE: this is the only place where the values for the ABR parameters can be set (their values are read-only).

Parameters:

initialBitRate - the value of the initial bit-rate (expressed in bps). The profile with the closes bit-rate value is selected when playback is started.

minBitRate - the value of the minimum bit-rate (expressed in bps). All profiles with a bit-rate lower than this value are ignored by the ABR switching algorithm.

maxBitRate - the value of the maximum bit-rate (expressed in bps). All profiles with a bit-rate grater than this value are ignored by the ABR switching algorithm.

abrPolicy - the policy that dictates the behavior of the bit-switching algorithm.
