zvbid(1)                       VBI proxy daemon                       zvbid(1)

NAME
       zvbid - VBI proxy daemon

SYNOPSIS
       zvbid [ options ]

DESCRIPTION
       zvbid is a proxy for VBI devices, i.e. it forwards one or more VBI data
       streams to one or more connected clients and manages channel change
       requests.

OPTIONS
       -dev path
              Path of a device from which to read data.  This argument can be
              given several times with different devices.

       -buffers count
              Number of buffers to allocate for capturing VBI raw data from
              devices which support streaming (currently only video4linux,
              rev. 2)  A higher number of buffers can prevent data loss in
              case of high latency. The downside is higher memory consumption
              (typically 65kB per buffer.)  Default count is 8, maximum is 32.

       -nodetach
              Daemon process remains connected to the terminal from which it
              was started (e.g. so that you can stop it by pressing Control-C
              keys).  Intended for trouble shooting only.

       -kill  Terminates a proxy daemon running for the given device.

       -debug level
              Enables debug output: 0= off(default); 1= general messages; In
              addition 2, 4, 8, ... can be added to enable debug output for
              various categories.

       -syslog level
              Enables syslog output.

       -loglevel level
              Log file level

       -logfile path
              Path to the log file.

       -maxclients count
              Max. number of clients which are allowed to connect
              simultaneously.

       -help  Print a short description of all command line options.
