Method Detail

getContentSize

protected long getContentSize()
Description copied from class: AbstractBox
Get the box's content size without its header. This must be the exact number of bytes that getContent(ByteBuffer) writes.

Specified by:
getContentSize in class AbstractBox
Returns:
Gets the box's content size in bytes
See Also:
AbstractBox.getContent(java.nio.ByteBuffer)

_parseDetails

public void _parseDetails(ByteBuffer content)
Description copied from class: AbstractBox
Parse the box's fields and child boxes if any.

Specified by:
_parseDetails in class AbstractBox
Parameters:
content - the box's raw content beginning after the 4-cc field.

getContent

protected void getContent(ByteBuffer byteBuffer)
Description copied from class: AbstractBox
Write the box's content into the given ByteBuffer. This must include flags and version in case of a full box. byteBuffer has been initialized with getSize() bytes.

Specified by:
getContent in class AbstractBox
Parameters:
byteBuffer - the sink for the box's content

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
