NAME

       dvsource-alsa - audio source for DVswitch

SYNOPSIS

       dvsource-alsa [OPTIONS] [-s ntsc|pal] [-r 48000|32000|44100] [DEVICE]

DESCRIPTION

       dvsource-alsa  uses  ALSA  to capture audio and sends it to DVswitch together with a dummy
       video stream.

       The optional DEVICE argument is a PCM device name. See the ALSA documentation ⟨http://
       www.alsa-project.org/alsa-doc/alsa-lib/pcm.html#pcm_dev_names⟩ for an explanation of these
       names.

OPTIONS

       -h, --host=HOST

       -p, --port=PORT
              Specify the network address on which DVswitch is listening.  The host  address  may
              be specified by name or as an IPv4 or IPv6 literal.

       -s, --system=ntsc|pal
              Specify the video system to use.  This must match the system used by DVswitch.  The
              default is "pal".

       -d, --rate=48000|32000|44100
              Specify the sample rate, in Hz.  The default is 48000.

       -d, --delay=DELAY
              Specify the time by which audio should be delayed, in seconds.  The delays in  live
              audio  and  video  sources  need  to be closely matched in order that the audio and
              video signals will be synchronised in the output of DVswitch.  The default is 0.2.
