Interface BitRateControl

public interface BitRateControl

extends Control

This interface is a Control for specifying the parameters for bit rate. The bit rates are specified in bits per second. This Control can be used to export the bit rate information for an incoming stream or to control the encoding bit rate of a compressor.

Since:

JMF 2.0

Method Summary

int	getBitRate() Returns the current bit rate of the owning object.
int	getMaxSupportedBitRate() Returns the highest bit rate that this object can encode the data stream to.
int	getMinSupportedBitRate() Returns the lowest bit rate that this object can encode the data stream to.
int	setBitRate(int bitrate) Sets the bit rate of the owning object.

Method Detail

getBitRate

public int getBitRate()

Returns the current bit rate of the owning object. If the stream is of variable bit rate, then the value returned is an instantaneous or average bit rate over a period of time. The bit rates are specified in bits per second.

Returns:

the bit rate

setBitRate

public int setBitRate(int bitrate)

Sets the bit rate of the owning object. This is mostly relevant in the case of encoders. If the bit rate cannot be controlled, then the return value is -1. The bit rates are specified in bits per second.

Returns:

the bit rate that was actually set on the object, or -1 if the bit rate is not controllable.

getMinSupportedBitRate

public int getMinSupportedBitRate()

Returns the lowest bit rate that this object can encode the data stream to. The bit rates are specified in bits per second.

Returns:

the lowest supported bit rate

getMaxSupportedBitRate

public int getMaxSupportedBitRate()

Returns the highest bit rate that this object can encode the data stream to. The bit rates are specified in bits per second.

Returns:

the maximal supported bit rate
