Yesterday I published a quick post about a basic MPEG -> FLV video conversion method using FFMPEG.
Today I want to share another great usage of FFMPEG: stripping a
video’s audio and creating an MP3. As an added bonus, I’ll be ripping
the audio from a great YouTube video using youtube-dl, a python script with loads of options for downloading YouTube videos.
The youtube-dl Shell Script

well-versed with the permissions side of Unix. I eventually figured it
out but if you have trouble installing youtube-dl or simply want to use
its advanced options, check out youtube-dl’s documentation. youtube-dl also provides an option to read a text file with a list of videos and will do a batch download. Note: youtube-dl allows you to set an output file name but it didn’t appear to be working. If you’d like a more simple method, Mark Sanborn wrote a great post on ripping YouTube videos using wget.
The FFMPEG Shell Script
1.davidwalsh83$ ffmpeg -i tlWpnLdPwvk.flv RodStewartMaggieMay.mp3As I did with youtube-dl, I chose the most basic usage of FFMPEG. FFMPEG’s documentation provides you a list of all of the possible conversion options if you need them.
Use the video player above to listen to the result. The video I chose
is a live version of Maggie May by Rod Stewart recorded at Royal Albert
Hall in the Knightsbridge area of the City of Westminster, London,
England. The video is from Rod’s One Night Only DVD
which I HIGHLY recommend. This is the best version of Maggie May that
exists (my opinion but, as you know, when is my opinion not correct?)
Enjoy!
