: get the mp3 file from a video. See

To extrapolate the mp3 file of a video we need to install "ffmpeg" on the PC, then open the Terminal (Applications -> Accessories -> Terminal) and type: sudo apt-



get install ffmpeg commands to run the video file, we care about are these:

basic command
ffmpeg-i InputFileVideo.flv OutputFileAudiomp3

In automatic it will create files of 64 kb / s. But you can choose the bitrate with the "-ab"
ffmpeg-i-ab 128k InputFileVideo.flv OutputFileAudio.mp3

If the file already has a flv mp3 audio, no need to re-encoding. You can simply copy the audio stream. This will keep the quality of audio and video will be much faster since there is no re-encoding phase.
ffmpeg-acodec copy-i InputFileVideo.flv OutputFileAudio.mp3

not know what kind of audio? Just do this: ffmpeg-i
InputVieo.flv
