Lossless concatenation of MP4 files using ffmpeg (H.264 video and AAC audio)
"""
This is a script that concatenates mp4 files using the method recommended at
https://trac.ffmpeg.org/wiki/Concatenate, i.e. it does the equivalent of
ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4
To run this script, execute
python mp4concat input1.mp4 input2.mp4 ... --output output.mp4
in a Python environment in which 'click' is installed (execute 'pip install click' otherwise)

2018-06 Debug Jupyter notebooks with PyCharm

Did you ever had to debug some large cell in a Jupyter notebook? In the below I share my experience on the subject. We'll review the classical methods for debugging notebooks, and finally I'll show how to set breakpoints in PyCharm for code being execute in a jupyter notebook, and benefit of the comfort of a real Python IDE for debugging.

Debug in the notebook

Before I actually describe what Pycharm can do, we quickly review the jupyter commands for debugging.
