Let me post two ways of downloading youtube videos which I know:
METHOD 1:Downloading without installing any package:
- Go to video page and allow the video to get buffered fully.
- Minimize the browser window.
- Now go to the location /tmp.
- To go to /tmp follow these steps:
- open any drive.
- click ctrl+L.
- type /tmp and press enter.
- U can see a video file stored that directory.
- Copy that file and save in any other directory,for example in desktop.
METHOD 2:
This method needs to install a package called Clipgrab.
To install this package go to ubuntu software centre and type Clipgrab.Then click install.
You may also install this package by giving the following command in terminal:
sudo apt-get install clipgrab
Now copy the video url and paste it in the clipgrab package.After a while click grab this clip!.
Now your video gets downloaded and saved in the directory you specified..
Enjoy watching!!!!
