All Implemented Interfaces:

Box

public final class BitRateBox
extends AbstractBox

class BitRateBox extends Box('btrt') {
unsigned int(32) bufferSizeDB;
// gives the size of the decoding buffer for
// the elementary stream in bytes.
unsigned int(32) maxBitrate;
// gives the maximum rate in bits/second
// over any window of one second.
unsigned int(32) avgBitrate;
// avgBitrate gives the average rate in
// bits/second over the entire presentation.

BitRateBox

public BitRateBox()

Method Detail

getContentSize

protected long getContentSize()

Description copied from class: AbstractBox

Gets the box's content size. This excludes all header fields:

• 4 byte size
• 4 byte type
• (large length - 8 bytes)
• (user type - 16 bytes)

Flags and version of a full box need to be taken into account.

Specified by:

getContentSize in class AbstractBox

Returns:

Gets the box's content size in bytes

_parseDetails

public void _parseDetails(java.nio.ByteBuffer content)

Description copied from class: AbstractBox

Implement the actual parsing of the box's fields here. External classes will always call AbstractBox.parseDetails() which encapsulates the call to this method with some safeguards.

Specified by:

_parseDetails in class AbstractBox

getContent

protected void getContent(java.nio.ByteBuffer bb)
                   throws java.io.IOException

Description copied from class: AbstractBox

Writes the box's content into the given ByteBuffer. This must include flags and version in case of a full box. bb has been initialized with getSize() bytes.

Specified by:

getContent in class AbstractBox

Parameters:

bb - the box's content-sink.

Throws:

java.io.IOException - in case of an exception in the underlying OutputStream.

getBufferSizeDb

public long getBufferSizeDb()

setBufferSizeDb

public void setBufferSizeDb(long bufferSizeDb)

getMaxBitrate

public long getMaxBitrate()

setMaxBitrate

public void setMaxBitrate(long maxBitrate)

getAvgBitrate

public long getAvgBitrate()

setAvgBitrate

public void setAvgBitrate(long avgBitrate)
