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.
