Constructor Detail

AbstractSampleEncryptionBox

protected AbstractSampleEncryptionBox(String type)
Method Detail

getOffsetToFirstIV

public int getOffsetToFirstIV()

_parseDetails

public void _parseDetails(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

getSampleCount

public int getSampleCount()

getEntries

public List<AbstractSampleEncryptionBox.Entry> getEntries()

setEntries

public void setEntries(List<AbstractSampleEncryptionBox.Entry> entries)

getAlgorithmId

public int getAlgorithmId()

setAlgorithmId

public void setAlgorithmId(int algorithmId)

getIvSize

public int getIvSize()

setIvSize

public void setIvSize(int ivSize)

getKid

public byte[] getKid()

setKid

public void setKid(byte[] kid)

isSubSampleEncryption

public boolean isSubSampleEncryption()

isOverrideTrackEncryptionBoxParameters

public boolean isOverrideTrackEncryptionBoxParameters()

setSubSampleEncryption

public void setSubSampleEncryption(boolean b)

setOverrideTrackEncryptionBoxParameters

public void setOverrideTrackEncryptionBoxParameters(boolean b)

getContent

protected void getContent(ByteBuffer bb)
                   throws 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:
IOException - in case of an exception in the underlying OutputStream.

getContentSize

protected long getContentSize()
Description copied from class: AbstractBox
Gets the box's content size. This excludes all header fields:

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

getBox

public void getBox(WritableByteChannel os)
            throws IOException
Specified by:
getBox in interface Box
Overrides:
getBox in class AbstractBox
Throws:
IOException

createEntry

public AbstractSampleEncryptionBox.Entry createEntry()

equals

public boolean equals(Object o)
Overrides:
equals in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

getEntrySizes

public List<Short> getEntrySizes()
