Is there an application that allows me to extract the audio from a MP4 or FLV video file and store it as an MP3 file for use in a portable media player?

You can do the same in 12.04 by using several software.
Using WinFF
Install winff and libavcodec-extra first
sudo apt-get install winff libavcodec-extraOpen Winff from dash
Then in Winff window, do these
Add file
Select what catagory to convert (select Audio)
Select Audio file format (mp3)
Type the output folder for converted file
- Then click the Convert button. You can also click Options button to file tune the audio format and other options.
Using VLC
Install VLC and "libavcodec-extra" package first
sudo apt-get install vlc libavcodec-extraOpen VLC from dash by pressing
Superkey and typing "VLC" there
Then from top panel menu, Select Media → Convert/Save.
Then Add file to convert in the new window. Then click Convert button.
In the new window, Select the directory for output file, select the conversion profile (Audio mp3) and click Start button.
Using command line
First install the tools
sudo apt-get install ffmpeg libavcodec-extra libav-toolsIf you are using
Use this simple command to extract the audio file
avconv -i /input-file-name-with-path output-filename.mp3For example to convert the "How fast.ogg" video file into
how-fast.mp3use this command:avconv -i /usr/share/example-content/Ubuntu_Free_Culture_Showcase/How\ fast.ogg how-fast.mp3See the manual page for more options and information.

1I think in the command line the libavcodec-extra-53 package is important. Before I installed it, I do not succeded to convert to mp3. Commented Oct 22, 2012 at 16:50

4Now I think it's 56. But why not just install the
libavcodec-extrametapackage? Commented Jun 7, 2015 at 7:56 -

avconv. I've been looking for a simple command-line way to do this for a long time! Commented Jan 3, 2017 at 8:28
you can do it using ffmpeg. Install ffmpeg using following command:
sudo apt-get install ffmpeg libavcodec-unstripped-52
The package libavcodec-unstripped-52 is available in Multiverse repo, so you will need to enable it.
After installing these packages, you can use a command like the one below to extract the audio as mp3:
ffmpeg -i video.mp4 -f mp3 -ab 192000 -vn music.mp3
The -i option in the above command is simple: it is the path to the input file. The second option -f mp3 tells ffmpeg that the ouput is in mp3 format. The third option i.e -ab 192000 tells ffmpeg that we want the output to be encoded at 192Kbps and -vn tells ffmpeg that we dont want video. The last param is the name of the output file.

3I prefer the newer audio/video converter avconv. syntax is similar to ffmpeg: 'avconv -i input.mp4 -vn -qscale 1 output.mp3' ... -qscale 1 ensures maximum quality (and VBR) and the type of the encoder is deduced from the output file extension.– arielfCommented Jul 8, 2012 at 4:07

1Running this program, it says: *** THIS PROGRAM IS DEPRECATED *** This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.– melmiCommented Dec 12, 2013 at 16:52

Nice answer, because ffmpeg can be used on mac os, and I don't need to switch to ubuntu :)– kelinCommented May 9, 2016 at 21:18
soundconverter is another tool that can convert audio formats and also video to audio only:
or via the terminal:
sudo apt-get install soundconverter

I had to do sudo apt-get install ubuntu-restricted-extras to enable conversion to mp3s Commented May 31, 2016 at 4:19
It is very easy to do with WinFF (install it), which is a GUI for ffmpeg.
- Click add.
- Select a video file
- In Convert to, select Audio
- Select an audio codec
- Click Convert. (Notice that the Convert button might sometimes disappear if the window is too small. Make the window larger if you don't see it)
Done. Screenshot:

Audacity can also open a flv file and export it as mp3, flac and other formats
My favorite way is to use gnome-terminal -e "avconv -i %f %f.mp3" in Thunar custom actions. Even better, to get a constant bitrate of 192 kbps:
avconv -i %f -c:a libmp3lame -ac 2 -b:a 190k %f.mp3
In fact the audio in a flv (and mp4) file is in aac format. To stay as close as possible to the quality of the original sound, consider using the aac in an m4a container. If the mp3 format is a must, consider the initial bitrate of the aac file when converting to mp3. More here.
soundconverter is another tool that can convert audio formats and also video to audio only.
It can be installed in the Software Center (by clicking the above link) or by running these commands in a Terminal (Ctrl+Alt+T):
sudo apt-get update
sudo apt-get install soundconverter

have you tested converting flv to mp3 in soundconverter? while converting mp4 video to mp3 works ok, in my case it works endlessly with no result to a flv file that winff converts in seconds– user47206Commented Feb 1, 2013 at 11:58

also install ubuntu-restricted-extras for mp3 conversion Commented May 31, 2016 at 4:20
You can convert your media files using VLC player. Load a media file => to convert: Menubar > Media > Convert/Save.

Thanks for the tip. I have been using VLC for a while but I didn't know of this feature– MysterioCommented May 11, 2012 at 17:57
You can achieve this with a simple command:
ffmpeg -i yourVideoInput.mp4 theAudioOutput.mp3
mkvtoolnix is a good package, it can extract by tracks, chapters or specific timings at the same time.
mkvmerge -i <input_video>
Track ID 0: video (MPEG-4p10/AVC/h.264)
Track ID 1: audio (AC-3/E-AC-3)
Track ID 2: audio (AC-3/E-AC-3)
You want to extract TrackID 2 by each chapters (assume the long video)
mkvmerge -o <output_audio> --audio-tracks 2 --no-video --split chapters:all <input_video>
You get numbered files, output_audio001, output_audio002...
Then convert each audio file to mp3

Transmageddon
You can also use Transmagedon Video Converter to convert video file to sound file.
Or in trminal:
sudo apt-get install transmageddon
To convert to MP4, you have to select in Choose Video Codec as No Video.
Can convert to .ogg by selecting the Presets as Ogg.
I used VLC media player to convert a .flv file to a .mp4/mp3 file. Audacity failed at even loading the complete file. It could load only the first 8 seconds and I could export the audio. But, VLC was the fastest! Let every other piece of software be!
mp4andflvvideo files containaacaudio. To have that audio asmp3is easy, but there may be some problems converting between lossy formats. The input and output bit-rates have to be considered. See the discussions in the different answers under this question. Maybe the best solution would be to keep the audio inaacformat, that is in them4acontainer - more heremp4andflvvideo files can contain sound in many formats includingaacandmp3. For example the FLV container specification mentions no less than 15 types of supported sound codecs/types.aacinmp4tomp3inmp3) OR just copy it over to the new container (mp3inmp4tomp3inmp3).
