SND_PCM_NEW_STREAM(9)						      PCM API						     SND_PCM_NEW_STREAM(9)

NAME

       snd_pcm_new_stream - create a new PCM stream

SYNOPSIS

       int snd_pcm_new_stream(struct snd_pcm * pcm, int stream, int substream_count);

ARGUMENTS

       pcm
	   the pcm instance

       stream
	   the stream direction, SNDRV_PCM_STREAM_XXX

       substream_count
	   the number of substreams

DESCRIPTION

       Creates a new stream for the pcm. The corresponding stream on the pcm must have been empty before calling this, i.e. zero must be given to
       the argument of snd_pcm_new.

RETURN

       Zero if successful, or a negative error code on failure.

NAME

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

SYNOPSIS

	 use Audio::FLAC::Decoder;
	 my $decoder = Audio::FLAC::Decoder->open("song.flac");
	 my $buffer;
	 while ((my $len = $decoder->sysread($buffer) > 0) {
	   # do something with the PCM stream
	 }

	 OR

	 open FLAC, "song.flac" or die $!;
	 my $decoder = Audio::FLAC::Decoder->open(*FLAC);

	 OR

	 # can also be IO::Socket or any other IO::Handle subclass.
	 my $fh = IO::Handle->new("song.flac");
	 my $decoder = Audio::FLAC::Decoder->open($fh);

DESCRIPTION

       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.

CONSTRUCTOR

   "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.

INSTANCE METHODS

   "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
