Audio::FLAC::Decoder - An object-oriented FLAC decoder

"open($filename)"
       Opens an FLAC file for decoding. It opens a handle to the file or uses an existing handle and initializes
       all of the internal FLAC decoding structures.  Note that the object will maintain open file descriptors
       until the object is collected by the garbage handler. Returns "undef" on failure.

       This module provides users with Decoder objects for FLAC files.  One can read data in PCM format from the
       stream, seek by pcm samples, or time.

"sysread($buffer,[$size])"
       Reads PCM data from the FLAC stream into $buffer.  Returns the number of bytes read, 0 when it reaches
       the end of the stream, or a value less than 0 on error.  The optional size can specify how many bytes to
       read.

   "raw_seek($pos)"
       Seeks through the compressed bitstream to the offset specified by $pos in raw bytes.  Returns 0 on
       success.

   "sample_seek($pos)"
       Seeks through the bitstream to the offset specified by $pos in pcm samples. Returns 0 on success.

   "time_seek($pos,[$page])"
       Seeks through the bitstream to the offset specified by $pos in seconds. Returns 0 on success.

   "bitrate([$stream])"
       Returns the average bitrate for the specified logical bitstream.  If $stream is left out or set to -1,
       the average bitrate for the entire stream will be reported.

   "time_total([$stream])"
       Returns the total number of seconds in the bitstream.

   "raw_tell()"
       Returns the current offset in bytes.

   "time_tell()"
       Returns the current offset in seconds. - NOT YET IMPLEMENTED
