TYPE
public static final String TYPE
- See Also:
- Constant Field Values
TrackFragmentHeaderBox
public TrackFragmentHeaderBox()
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
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
.
_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
