I know you have tried many ways to download your favourite youtube video to your hard drive. you may have used many tools for that. But suddenly on one day, your fav tools stop working. Why? Because, youtube changes their technology time to time in caching the videos in your browser. There are many Gnu/Linux based application to download youtube. Clive, gvdown are best examples. My favourite application was Clive. Anyway Clive is no longer works in my machine. To use Clive any longer, I have to upgrade it or re-install it. So I decided to get them without any software. How could I do that?
Whatever file to run in your computer from the internet, it has to cache it first in the local system. May it be a png or gif, flv or mp3 it has to do so. So the site, caches the file in the temp location of your system. In the case of youtube video, you have to find where the file is cached in your local system. Its that simple. Once you find where is the file is cached, you almost got the file. Before proceeding you have to understand the following things to operate.
- Find out the way to view all cache files in your Mozilla Firefox browser
- Find out the way to view all cache files in your Computer (Gnu/Linux or Windows or Mac etc)
- Open Mozilla Firefox and in the address bar type as "about:cache" (without quotes)
- In "Memory cache device", click on "List Cache Entries"
- Using Firefox "Find" tool, locate your youtube video.
- Click on a "Key" heavy file size. (say 3725647 bytes)
- Then you will get enough info on that particular key. Just Right-click on the key and save to the hard disk
- By default, the file name will be "videoplayback". Rename it with a .flv extension
- Play it with Mplayer or vlc player
- If you wish to convert as mp3 or any other formats, use ffmpg.
- The command to convert as
ffmpeg -i inpuvvideofile.flv outputaudiofile.mp3
- Thats all. Any doubts?
