Binary package “dv4l” in ubuntu eoan

Redirect V4L API to access a camcorder from a V4L program

 dv4l enables programs to access a dv1394 (Firewire) camcorder by using
 the video4linux (V4L) API. dv4lstart uses the LD_PRELOAD facility to
 intercept calls to the V4L API and make the camcorder's videostream available.
