Hate to sound like a complete noob since that is what I am but, all I get when I use this method (infact anytime i use the command line) is a message that says, no such file or directory. I assume I change the “input_file.flv” to the name of the actual file to be converted. any ideas.???

Simple, works, but when I extract from .flv which has 128 kbps bitrate I’v got 64kbps bitrate in the output file. How to extract in the same quality?

Good sugestions! I would also throw in soundconverter (found in the repositories). Just make sure you have the proper codecs installed. Once the output is confiured it’s drag, drop, convert and done. Has worked with avi, mkv, mov, flv, mpeg, and mp4 video formats for me.

Here’s a simple nautilus script (I made it) which simply converts one or more selected files using the command described above. It shows progress window using zenity (which needs some tweak to show the right percentage but I’m on hurry now) and the current filename.

Note: save the following script as file (no extension needed) in the nautilus scripts dir (~/.gnome2/nautilus-scripts) and don’t forget to make that file executable! (chmod +x … )

#!/bin/bash
cnt=0
total= $#
step= 100/$total

(while [ $# -gt 0 ]; do
file=$1
mp3file=`echo “$file” | sed ‘s/\.\w*$/.mp3/’`
echo “# $file to $mp3file”

/usr/bin/ffmpeg -ab 128 -y -i “$file” “$mp3file”
cnt= $cnt+$step
echo “$cnt”
shift
done) | zenity –title=”Converting to mp3″ –progress –text=”Converting to 128Kbs mp3 file…” –auto-close –percentage=0

interesting little cross flame upthread – the command line can be seen as medieval, or it can be seen as matrix-chic. Very much a matter of taste that one, regardless of what you can or cannot do with it. As for feeling sorry for windows users, it is possible to use a cli in windows i believe.

Anyway nice command reference. As for compression issues with flash videos, I assume it is reasonable to replace the output format with flac (for instance)?

Opps — forgot the closing }. That command line is:

#> for i in *.flv ; do ffmpeg -i ${i} ${i:s/flv/wav/} ; done

Especially when you can use the full power of the CLI and do this:

#> for i in *.flv ; do ffmpeg -i ${i} ${i:s/flv/wav/” ; done

And do them all at once. Change *.flv to *.mp4 or what have you. Change ${i:s/flv/wav} to ${i:s/flv/mp3} or ${i:s/flv/ogg} or what you want.

This little command line loop will list each file that matches *.flv, feed it into whatever command follows the ‘do’ and it’s position in the command is wherever you put the ${i}. The added ‘s/flv/wav/’ means to search ‘s’ for flv and replace with wav. This substitution occurs *before* ffmpeg actually is run.

Eazy squeezy.

I installed winff out of curiosity. It’s great but 1) I wouldn’t even have understood how to extract the audio without Willem’s advice, so it’s not better than the command line; 2) typing ffmpeg -i input_file.avi output_file.mp3 on the command line is so much faster that I don’t care looking medieval. This is one of those cases when I feel sorry for Windows users that have to waste so much time with the file open dialog and all the other GUI controls.
I’m using audacity and openshot for my other video production steps, so I’m not always medieval. I just like to be efficient.

Hi,

You can use an Any File to Audio Converter to convert video to mp3.

When will the Linux-world understand at last average computer users DON’T WANT THE COMMAND LINE CAUSE IT’S MEDIEVAL?
When you want to extract audio from videofiles in Linux just use WINFF.
That’s an excellent GRAPHICAL frontend for FFMPEG. WINFF is also available for Windows. Just import the videofile in WINFF. Select Convert to Audio, select the audioformat of your choice, fill in the desired bitrate (ie for mp3 128 kbps) and there it goes.
WINFF is in the repositories of several major Linux distributions like Ubuntu and OpenSUSE. See also: http://winff.org/html_new/
