      • _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

      • setMaxBitrate

        public void setMaxBitrate​(long maxBitrate)
        Sets the maximum rate in bits/second over any window of one second.
        Parameters:
        maxBitrate - max bit rate

      • getAvgBitrate

        public long getAvgBitrate()
        Gets the average rate in bits/second over the entire presentation.
        Returns:
