A simple script to convert .mp4 to .pdf, util for extracting slides from a video file.
- Python 3.6 or latter
- Package opencv-python.
- Package Numpy.
- Package Scikit-image.
- Package Pillow.
In the project folder run python3 mp4_to_pdf.py -h to see the following help message:
usage: mp4_to_pdf.py [-h] [--out OUT] [--nframe NFRAME] [--lim LIM]
[--diff DIFF] [--ssim SSIM] [-v]
infile
positional arguments:
infile The .mp4 file path.
optional arguments:
-h, --help show this help message and exit
--out OUT The .pdf output file path. Defaults to the .mp4 file name
plus .pdf.
--nframe NFRAME Read every N'th frame. Defaults to 24.
--lim LIM Read only N frames.
--diff DIFF Min diff needed for checking. Defaults to 0.90 (0=Nothing
like, 1=Identical).
--ssim SSIM Structural similarity threshold. Defaults to 0.90
(0=Nothing like, 1=Identical).
-v Verbose mode.
Example:
python3 mp4_to_pdf.py video.mp4 --out output.pdf --nframe 100 -v
Will convert the file named 'video.mp4' (in the same directory), read only every 100th frame (speeds up things) and save as 'output.pdf' (in the same directory).
Verbose mode -v is highly recommended as it displays progress.
Including --lim 5000, for example, would cause it to only read the first 5000 frames, instead of the whole file.
If you would like to finetune and improve the result, you may change --diff and --ssim default arguments.
Changing --ssim usually results in better results than changing --diff, but since --diff is faster and is used first, changing it may lead to better speed-ups. Be careful as --diff is highly sensitive.
After creating a Python 3 Virtual Environment, use pip install -r requirements.txt to install all required dependencies. If you pretend to use pyinstaller, install it with pip install -r requirements.txt.
In order to "package" with Pyinstaller, run pyinstaller mp4_to_pdf_gui.spec in your Virtual Enviroment.
