I disided to download my Highload++ Conference speech, but how to do it efficient way?
Fount a great python lib and cmd tool: pytube (github repo)
All you need is to install and execute it :)
pip install --upgrade pytube
pytube 'link'
Note: you also can chose the video quality by pytube --list 'link'; pytube --itag 137 'link' but it this case you need to download audio separately!
