A GPU accelerated image viewer for the Raspberry Pi.
Due to deprecation of the OpenMax API and the unavailability of those libraries on arm64, this project only supports 32bit operating systems.
You will need the development header for libjpeg and libpng (Debian: libjpeg-dev, libpng-dev). Then build it on the Pi with:
make ilclient
make
And install with:
sudo make install
USAGE:
omxiv [OPTIONS] image1 [image2] ...
omxiv [OPTIONS] directory
Without any input it will cycle through all
supported images in the current directory.
OPTIONS:
-h --help Print this help
-v --version Show version info
-t n Time in s between 2 images in a slide show
-b --blank Set background to black
-T --transition type type: none(default), blend
--duration n Transition duration in ms
--win 'x1 y1 x2 y2' Position of image window
--win x1,y1,x2,y2 Position of image window
-m --mirror Mirror image
-a --aspect type type: letterbox(default), fill, center
-o --orientation n Orientation of the image (0, 90, 180, 270)
-l --layer n Render layer number
-d --display n Display number
-i --info Print some additional infos
-k --no-keys Disable keyboard input
-s --soft Force software decoding
--ignore-exif Ignore exif orientation
-f --file-list Read a list of images from a text file
-r --randomize Randomize the list of images
--once Only show the image(s) once, exit after the last
