This source accepts the following parameters:

size

The size of the video to generate. For the syntax of this option, check the "Video size" section in the ffmpeg-utils manual.

framerate

The framerate of the generated video. It may be a string of the form num/den or a frame rate abbreviation.

For example, to generate a frei0r partik0l source with size 200x200 and frame rate 10 which is overlaid on the overlay filter main input:

frei0r_src=size=200x200:framerate=10:filter_name=partik0l:filter_params=1234 [overlay]; [in][overlay] overlay
