FLV – Flash Video – is very popular on the web for some time, especially on sites streaming audio or video like YouTube, Dailymotion. We’ll see how to convert flv file downloaded from one of these flv to mp3, mpeg or avi thanks to the excellent open source ffmpeg library.

Installation

First Install Package ffmpeg with below command

If you need these codecs,  download and install them using the following commands:

sudo cp all-20061022 / * / usr / lib / codecs /

Ffmpeg is also available under Windows. You find your happiness on this page. Note, I never installed ffmpeg under win and therefore I can not say more about it.
Usage
