zvbid: VBI proxy daemon


zvbid - VBI proxy daemon


zvbid [ options ]


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.


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