DFBSee is an image viewer and video player using DirectFB. It asks DirectFB for a suitable media provider for the given files and displays them.

dfbsee accepts the following command-line options:

-v, --version

Output the version info.

-f, --fullscreen

Start in fullscreen mode.

-z, --zoom

Start with maximal zoom.

-r, --override-ratio [n:n]

Allows to override the aspect ratio. If this option is set, but no aspect ratio is specified, the screen's aspect ratio is used.

-c, --corner

Do not center images/video but put them into the top left corner.

-t, --time

Show current time.

-s, --slide-show <seconds>

Switch to next image/video after the specified time of inactivity.

-m, --mode <nnn>x<nnn>@<nn>

Tries to set the framebuffer to the given resolution and bit-depth. If this fails or this option is not used the first mode found in /etc/fb.modes is used.
