YouTube, FFMPEG, and MP3 Conversion

By  on  
Rod Stewart and Ron Wood

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

#command
davidwalsh83$ youtube-dl.py http://www.youtube.com/watch?v=tlWpnLdPwvk

#output
[youtube] Setting language
[youtube] tlWpnLdPwvk: Downloading video webpage
[youtube] tlWpnLdPwvk: Extracting video information
[youtube] tlWpnLdPwvk: URL: http://www.youtube.com/get_video?video_id=tlWpnLdPwvk&t=vjVQa1PpcFMZ4TkTSYXamGxmLZq-ot2l8Jx-HiNAf0I=&el=detailpage&ps=
[download] Destination: tlWpnLdPwvk.flv
[download] 100.0% of 18.78M at   53.98k/s ETA 00:00

The initial install of youtube-dl was tough but only because I'm not 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

davidwalsh83$ ffmpeg -i tlWpnLdPwvk.flv RodStewartMaggieMay.mp3

As 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.

The Result

[audio:RodStewartMaggieMay.mp3]

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!

    Python ftw.

    Your FFmpeg code needs the -vn option so it doesn’t render the video. I believe it will be faster with the following code:

    $ ffmpeg -i tlWpnLdPwvk.flv -vn -acodec copy RodStewartMaggieMay.mp3

    All youtube flv audios are encoded in mp3 format, so a simple copy will reduce some unneeded tasks..

    Did youtube modify their FLV files so that ffmpeg gives a “Unknown Format” Error ?
