NAME

       roar_simple_stream - Opens a stream to RoarAudio's sound server

SYNOPSIS

       #include <roaraudio.h>

       int roar_simple_stream(int rate, int channels, int bits, int codec, char * server, int dir, char * name);

DESCRIPTION

       This  creates a new stream to RoarAudio. Normally you want to use one of roar_simple_play(3), roar_simple_monitor(3), roar_simple_record(3)
       or roar_simple_filter(3).

       his functions are marked obsolete and will be removed very soon.  Please upgrade to VS API. See roar_vs_new_simple(3).

PARAMETERS

       rate, channels, bits, codec, server, name
	      For an explanation on these parameters see roar_simple_play(3).

       dir    The direction of the new stream. See below for a list of valid directions.

STREAM DIRECTIONS

       ROAR_DIR_PLAY
	      This stream directions meens that a player streams data to the server in order to play it back.

       ROAR_DIR_RECORD
	      This direction is to record audio from the soundcard. This is used if for example you want to get data from your microphon  or  line
	      in.

       ROAR_DIR_MONITOR
	      This  direction  is  used  to get a copy of what the server sends to the soundcard. This can for example be used to stream the fully
	      mixed data to Icecast (see icecast2(1)).

       ROAR_DIR_FILTER
	      This is used to crate a filter stream: A filter stream is a stream used to filter the output of the sound server by some tool.  This
	      can  for	example be used for an software equalizer. The filter stream is the only bi-directional stream. You have to read some data
	      and write back data of exactly the same size.

       ROAR_DIR_OUTPUT
	      This is the type of the stream the server sends to the soundcard. You can not create such a stream. It's only listend for  complete-
	      ness.

RETURN VALUE

       On success these calls return a filehandle.  On error, -1 is returned.

NAME

       muroar_stream - Create a stream connected to a RoarAudio sound server

SYNOPSIS

       #include <muroar.h>

       muroar_t muroar_stream (muroar_t fh, int dir, int * stream, int codec, int rate, int channels, int bits);

DESCRIPTION

       This  function connects a stream to a sound server supporting the RoarAudio protocol.  It takes a connected control connection created with
       roar_connect(3) and converts it into a connected stream. The socket can no longer be used as control connection.

PARAMETERS

       fh     The connected control connection.

       dir    The stream direction for the new stream.	For playback of a waveform stream (PCM data) this is MUROAR_PLAY_WAVE.	For  all  possible
	      values see the offical muRoar manual.

       stream This  is a pointer to an integer muRoar stores the stream ID in.	If your application does not need to know the stream ID of the new
	      stream this can be set to NULL.

       codec  This is the codec to be used for the new stream.	For signed PCM in host byte order use MUROAR_CODEC_PCM or MUROAR_CODEC_PCM_S.  For
	      unsigned	PCM  use MUROAR_CODEC_PCM_U.  There are a lot other codecs defined. However using a codec not supported by the server will
	      result an failure of this call.  For all possible values see the offical muRoar manual.

       rate   This is the sample/frame rate the new stream will use.  For streams this setting does not make any sense set this to zero.

       channels
	      This is the number of channels for the new stream.  For streams this setting does not make any sense set this to zero.

       bits   This is the number of bits per sample to be used by the data.  For streams this setting does not make any sense set this to zero.

RETURN VALUE

       On success this call return the new stream IO handle.  This may be the same as the control connection or a new one and the control  connec-
       tion is closed. On error, MUROAR_HANDLE_INVALID is returned.

BUGS

       In failure where is no way to tell was was going wrong.

HISTORY

       This function first appeared in muRoar version 0.1beta0.
