Author: Werner Robitza [e-mail]

Requirements

• Python 3.5 or higher
• FFmpeg:
  • download a static build from their website)
  • put the ffmpeg executable in your $PATH

Installation

pip3 install --user ffmpeg_black_split

Or clone this repository, then run the tool with python3 -m ffmpeg_black_split.

Usage

Run:

ffmpeg-black-split <input-file>

This might take a while depending on the length of your input file. It'll then split the video into parts, prefixed by the original filename. The audio and video streams will be copied as-is.

The output will be placed in the current directory, with each file being named <input>_<start>-<end>.mkv.
