Clive is an open source tool that enables us to download the videos from sites such as youtube. No additional fancy plugins or browser extensions are needed. This is a really nice command line tool for downloading the videos. Executing apt-get using the command sudo apt-get install clive downloads the older python module. The tarball provided by sourceforge contains the newer perl based program.
Once clive is installed downloading the videos is as simple as viewing the videos on youtube. Once you are on the web-page on youtube that has the desired video.
1. Just open a terminal.
2. Change to the folder where the video is to be download.
3. Execute clive with the URL present in the web-browser
For example, the if the URL to view the video is http://www.youtube.com/watch?v=NAQY2TPhoIM, then execute the command clive with the URL as an argument.
ashwin@garuda:~/Videos/Lectures/LinearAlgebra$ clive http://www.youtube.com/watch?v=NAQY2TPhoIM
The response (of the older python based program) is
clive/0.4.3 (linux2; python/2.5.2; urlgrabber/3.1.0)
[log:on] [play:off] [encode:off] [throttle:off] [exists:skip]
status: 20KB 100% (1 of 1) [http://www.youtube.com/watch?v=NAQY2TPhoIM...]
status: checking file length... 94.323MB
queue: 1 (total: 94.323MB), failed: 0, skipped: 0.
Depending on the bandwidth speed the video shall be downloaded in the desired folder. One shortcoming of this program is that if the download is interrupted then rerunning the program shall result in the downloading the whole file.
