$ gphoto2 --capture-movie=5
Capturing 5 preview frames as movie to 'movie.mjpg'.
Movie capture finished (6 frames)
That's a “motion jpeg,” in case you were wondering what a
.mjpg
file is.
Basic Capture Commands and Variables
What you do with your new camera+Pi powers is up to you. These are the three main
capture commands:
--capture-image
Capture an image and keep it on the camera.
--capture-movie
Capture a movie file (depends on camera).
--capture-sound
Capture an audio clip.
You can also add
-and-download
to image capture, so
--capture-image-and-download
will take a photo and immediately download it to the computer.
These few commands should be enough to get you started, but explore
gphoto2
--help
to learn even more.
You might also want to include some of the following variables:
--filename
NAME
Specifies a filename, where
NAME
is the desired filename. You can create a default
value for this in
~/.gphoto/settings
. It accepts additions, including
%n
: (for incre-
menting numbers),
+ (for date and time information), and +%
(to keep the
filename in lowercase).
