## NAME

v4l-info - dump video4linux(2) device info to stdout

## SYNOPSIS

**v4l-info \[ device \]**

## DESCRIPTION

**v4l-info** just prints the v4l(2) device info, i.e. calls lots of ioctls and dumps the results to stdout.  It optionally accepts the device you want to query.  Default is /dev/video0.

Was written to help debug drivers, probably not that useful for end users ...
