Clone the repository:
git clone https://github.com/whit3rabbit/yt-cap-dl -
Navigate to the project directory:
cd yt-cap-dl -
Install the required dependencies:
python -m venv venv pip install -r requirements.txt
Before running the caption grabber, you must first populate the video links for the desired YouTube channel. To do this, run the following command:
python main.py video-links <channel_name>
Replace <channel_name> with the name of the YouTube channel you want to scrape video links from. You can provide the channel name with or without the "@" symbol.
This command will scrape the video links from the specified YouTube channel and store them in the SQLite database.
Once you have populated the video links, you can proceed to download and clean the video captions. To do this, run the following command:
python main.py download-captions <channel_name> [-w/--workers <num_workers>] [--no-proxy]
Replace <channel_name> with the name of the YouTube channel you want to download captions for. You can provide the channel name with or without the "@" symbol.
Optional arguments:
-w/--workers <num_workers>: Specify the number of worker threads to use for concurrent downloading. Default is 1.--no-proxy: Disable the use of proxies for downloading captions.
This command will download and clean the video captions for the specified YouTube channel using the video links stored in the database.
The tool also provides functionality to manage proxies for efficient downloading. You can perform the following actions related to proxies:
python main.py proxy-manager <action>
Replace <action> with one of the following:
download: Download the latest proxies from a GitHub repository.check: Check the validity of unchecked proxies in the database.update: Download the latest proxies and check their validity.all: Perform both thedownloadandcheckactions.
The project uses an SQLite database to store video links, downloaded videos, and cleaned captions. The database file is named youtube_data.db and is created automatically when running the scripts.
It is crucial to populate the video links using the video-links command before running the caption grabber. The caption grabber relies on the video links stored in the database to download and clean the captions. Failing to populate the video links prior to running the caption grabber will result in no captions being downloaded.
