Python Youtube Downloader

supports:

• age restricted videos (with and without user details)
• playlists
• searching
• downloading hls/dash manifests
• specific itags
• all requests made with asynchronous aiohttp with a single session, ensuring the fastest connections
• trimming start and end position of the video (time to byte range to avoid downloading entire video yet to come, i just cant find any code that does this)
• integratability with api's

Usage:

First time setup:

1. in command prompt

git clone https://github.com/Hecker5556/ytdownloader.git

2.

cd ytdownloader

3. if you haven't already, install python

this will download requirements, build exe and add to path (admin needed which will be asked almost on launch) python setup.py build

on linux this will add absolute path to PATH and chmod the file, it will print out what u need to use to execute, it will also write to usagecommand.txt incase u forgor

If you built and added to path, you can replace 'python ytdownload.py' with just ytdownload, make sure to open a new terminal

if you don't want to build, just run

pip install -r requirements.txt
