      • scanForSizeInfo

        public OggStreamSizeInfo scanForSizeInfo​(long firstPageOffset,
                                         int sampleRate,
                                         int targetSerial)
        Parameters:
        firstPageOffset - Absolute position of the first page in the stream.
        sampleRate - Sample rate of the track in the stream.
        Returns:
        If the data contains the header of the last page in the OGG stream, then stream size information, otherwise null.
