Installation

Download

Set FFmpeg path

  1. Download the FFmpeg 4.4 binary and put it somewhere.
  2. Edit the AppSettings.json file to set the path to FFmpeg's bin directory.

Or just run the download_ffmpeg.bat file.

Limitations

  • Video playback synchronization is not frame-accurate, not perfect.
