The command provided is used with the command-line video downloader tool yt-dlp, a powerful utility for downloading videos and audio from various websites like YouTube. Here's what each part of the command does:

Command Breakdown:

1. yt-dlp: Refers to the executable yt-dlp, which is invoked to run the tool.

2. -f "bv,ba":

   • The -f flag specifies the format of the media to download.
   • "bv,ba" is a shorthand to select "best video" (bv) and "best audio" (ba) streams separately. This means the tool will download the highest quality video and audio streams available, instead of a single combined file.
   • These separate streams will typically be merged into one file after downloading (if the necessary tools, like ffmpeg, are installed).

3. -o "%(title)s.f%(format_id)s.%(ext)s":

   • The -o flag specifies the output filename template for the downloaded file(s).
   • "%(title)s": This placeholder inserts the title of the video.
   • "f%(format_id)s": This adds the format ID being downloaded (useful to distinguish between different qualities or streams).
   • "%(ext)s": Adds the appropriate file extension based on the media type (e.g., .mp4, .webm, etc.).

Summary:

This command downloads the best available video and audio streams (bv,ba) of a given video and saves it with a filename that includes:

• The video's title.
• The format ID.
• The proper file extension.

Example result might look like:
Example Video Title.f248.mp4
Where 248 is the format ID and mp4 is the extension based on the media format.
