A complete, cross-platform solution to record, convert and stream audio and video.

Installation

Move FFmpeg folder to a location of your choice, such as C:\Program Files\.

Enable FFmpeg Through Command Prompt

  1. Control Panel → System and Security → System → Advanced system settings
  2. Advanced Tab → Environment Variables → System variables → Path
  3. Add C:\Program Files\FFmpeg\ (Separate multiple paths with semicolon ;)

Typing ffmpeg in CMD will now launch without needing to specify a direct path.
