How can I convert a YouTube video to a different format using ffmpeg?

To convert a YouTube video to a different format using ffmpeg, you can use the following command in the terminal:

ffmpeg -i input video URL -c:v video codec -c:a audio codec output file name.output format

Replace input video URL with the URL of the YouTube video, video codec with the desired video codec, audio codec with the desired audio codec, output file name with the name you want for the output file, and output format with the desired format (e.g., mp4, avi, etc.).

Make sure you have ffmpeg installed on your system before running the command.
