FFmpeg is the command line, cross-platform tool to record, convert, compress and stream audio/video files. Although the command line is easier to use for experience users but for new it's iron ball to chewing. Why not use GUI for FFmpeg? WinFF. WinFF is a GUI tool to convert and compress each file that FFmpeg can convert.
We often need to convert/compress audio or videos files to play on some small screen devices. Sometimes you pay for a movie but later on you find your smarphone is missing codecs for that and so not playing. You can easily convert any video with WinFF in any format you want. Let's see how to install and use it.
Installing WinFF is pretty easy. Simply add the following ppa and update local repositories and install WinFF.
Most Linux distros have WinFF in their default repositories, so first try to install without adding PPA.
$ sudo add-apt-repository ppa:paul-climbing/ppa
$ sudo apt-get update
$ sudo apt-get install winff
(Optional) Install the unstripped version of ffmpeg:
$ sudo apt-get install libavcodec-extra-53
