Key Features

• Video Metadata: Retrieve detailed metadata for YouTube videos, including title, duration, views, thumbnails, and more.
• Captions: Fetch and process captions (subtitles) for YouTube videos.
• YouTube Search: Perform YouTube searches and fetch metadata for the top results.

Installation

Install Meta-YT using pip:

pip install -U meta-yt

Usage

Here is a quick guide on how to use the library.

Importing Necessary Modules

from meta_yt import YouTube, Video, Caption

Initializing the YouTube Object

You can initialize the YouTube object either with a search query or a video URL.

Using a Search Query

yt = YouTube("cat videos")
print(yt.video.title)

Using a Video URL

yt = YouTube("https://www.youtube.com/watch?v=dQw4w9WgXcQ")
print(yt.video.title)

Fetching Captions

You can fetch captions for a video and convert them to SubRip (SRT) format.

captions = yt.video.get_captions(include_generated=True)
for caption in captions:
    print(caption.language_code)
    print(caption.auto_generated)
    print(caption.to_srt())

Since this library does not include a function to download or decrypt video streams, you will need to use external libraries such as YTDL or PyTube for those purposes.
