Generate images for Phenakistoscopes

Linux installation

I suggest you add under Linux a section for Debian, or modify the existing section:

sudo apt-get install python-pip
sudo pip install Pillow fpdf moviepy

to make installation easier for the Linux users.

fps option is not working

The --fps option does not work, video is always 10 fps, or transcoded from any other input-fps to 10 fps. This does not make sense.

The fps parameter should determine the number of flip-book images in the pdf output. See also #3 Let the user select the number of output images instead of the frame rate.

Let the user select the number of output images instead of the frame rate

Introduce a command-line parameter -n that takes the number of images to produce

[Suggestion] option to crop and/or to zoom the video before the flip-book is created

[Suggestions] To-Do list

Some suggestions in form of a to-do list:

avoid the "zero" 0 for counting, I suggest to always start with number "1" for the first "flip-book page"
Auto-generate a title image ("Deckblatt") with meta data like the filename and file creation date. Number should be "1", not "0" (zero).
Add a framework for a web-based service (upload or side-load of a video, then processing and download possibility)
