If it's not got to be millisecond accurate then a script could just
loop with the capture command and a sleep command to set the delay
between frames.
You could use streamer / camorama /xawtv / mjpegtools depending on your device.
Looking through the aptitude list also reveals uvccapture which MAY do
what you want:
Description: USB UVC Video Class snapshot software
The purpose of this software is to capture an image from a USB webcam at a
specified interval, and save it to a JPEG file, no other formats are supported.
.
Right now this software is really a hack, since still image support is not yet
available in the UVC driver. The program continually polls the UVC driver in
MJPEG mode, and at a specified interval writes a JPEG header and a single frame
to file, creating a JPEG
