Converting to mp3
Now install ffmpeg from the official repo.
sudo apt-get install ffmpeg
Next have a look to make sure the flv file has downloaded from youtube by typing
This will list all the flv files you have. What you should see is a flv file with the same name as the 'v' component of the youtube url you downloaded.
E.g if you downloaded
http://www.youtube.com/watch?v=_z-hEyVQDRA then you should have a file called
Next you need to copy that file name and then put it in an ffmpg command like
ffmpeg -i <file name>.flv -acodec libmp3lame <song name>.mp3
So for this example you would type
ffmpeg -i _z-hEyVQDRA.flv -acodec libmp3lame MasterOfPuppets.mp3
Once this has successfully completed you will now have the mp3 file you were after.
- For cleanup you may want to type
rm _z-hEyVQDRA.flv to get rid of the flv file that you no longer need.
