NAME

zvbid - VBI proxy daemon

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.

-kill

-loglevel level
