Examples

An example to overlay an image on top of a video and apply a filter on the video

python3 main.py -f /path/to/vid.ogg -o /path/to/overlay.jpg -fl frei0r-filter-emboss

The above command takes an ogg video format input file and an image format overlay file. It overlays the image on the video and applies the frei0r-filter-emboss filter and then it writes the output as an video.mp4.

Another example which takes two image format imputs and overlays one on top of the other and writes the output on image.{jpg,png}

python3 main.py -f /path/to/image -o /path/to/overlayimage -sx 0.5 -sy 0.5

The above command takes two image format inputs and overlays one on top of the other.

-sx 0.5 sets the x-position of the overlay to the center position releative to the imput image width.

-sy 0.5 sets the y-position of the overlay to the center position releative to the input image height.
