FFmpeg dependency

[sidedwards]

Description:

To improve the application's portability and reliability, we should find a way to make FFmpeg work on both server.py and cli.py without relying on the local ffmpeg (Homebrew) installation.

Tasks:

• Research alternative methods to install or bundle FFmpeg with the application
• Investigate using a containerization solution (e.g., Docker) to package FFmpeg along with the application
• Modify the server.py script to use the new FFmpeg setup
• Update the documentation and installation instructions to reflect the changes
• Test the application on different environments to ensure FFmpeg works correctly
