setv4l is a simple command line program for changing the picture settings of a video 4 linux device.
You can change (if the specified device allows) the following settings:
For each you can specify a value from 0 to 65535.
I wrote setv4l project for managing remote webcams. It was originally called vidcontrol, but I found out that a program with that name existed with FreeBSD.
· Just unpack it and do a make.
For my webcams I use the vidcat program for capturing. It is part of the w3cam package. However it does not comply to the v4l spec in respect to picture sizes (actually it doesn't set the size at all.....)
