Pytube Function

Powered by Pytube, this YouTube downloader function is capable of downloading videos at the highest available resolution, including 4K. It also offers the option to download only the audio file. Additionally, it provides detailed information about individual videos and playlists.

Features

• Powered by Pytube: Utilizes the Pytube library, a lightweight, dependency-free Python library for downloading YouTube Videos.
• High-Resolution Downloads: Capable of downloading videos at the highest available resolution, including 4K.
• Audio-Only Downloads: Provides the option to download only the audio file from a YouTube video.
• Video Details: Retrieves detailed information about individual videos.
• Playlist Details: Can also fetch information about YouTube playlists.
• FFmpeg Integration for High-Quality Videos: The function uses FFmpeg, a powerful multimedia framework, to merge video and audio files. This ensures that the downloaded videos maintain high quality, even when the video and audio are stored in separate files on YouTube. This is particularly useful for high-resolution videos where the audio and video are often separated.
