Extract Well Rail From A Youtube Video

Youtube is a bang-up source for watching videos or listening to music on-line via their website. But if y'all desire to download the video or well to your computer, y'all involve about exceptional tool, together with y'all involve to know the URL for the youtube video y'all wishing to download.

One such tool is youtube-dl, which is a python script. Unfortunately, youtube-dl is non pre-packaged amongst Debian Wheezy.

I downloaded the script lead from this spider web page:

 $ sudo scroll https://yt-dl.org/downloads/2013.09.24.2/youtube-dl -o /usr/local/bin/youtube-dl $ sudo chmod a+x /usr/local/bin/youtube-dl 

The syntax of youtube-dl is quite straight-forward.

To download the consummate youtube video (with the soundtrack), precisely furnish the URL of the video every bit a unmarried argument.

 $ youtube-dl http://www.youtube.com/watch?v=O-xlvalecI8  [youtube] Setting linguistic communication [youtube] O-xlvalecI8: Downloading video webpage [youtube] O-xlvalecI8: Downloading video information webpage [youtube] O-xlvalecI8: Extracting video data [youtube] O-xlvalecI8: Encrypted signatures detected. [youtube] O-xlvalecI8: Downloading js thespian vflUKrNpT [download] Destination: Give me crude inwards my lamp-O-xlvalecI8.flv [download] 100% of 11.73MiB inwards 00:43 

This creates a Flash Video (.flv) file inwards your local difficult drive. To sentry the video off-line, opened upwards the .flv file amongst a media thespian application such every bit VLC or Totem.

If it is precisely the well rail that y'all want, non the consummate video, y'all tin withal operate youtube-dl. However, to produce well extraction, youtube-dl requires two extra programs to last installed. Namely, it requires ffmpeg or avconv, together with ffprobe or avprobe.

On my Debian Wheezy system, I installed avconv together with avprobe yesteryear precisely installing this package:

 $ apt-get install libav-tools 

Finally, y'all tin run youtube-dl similar this to extract the well rail only:

 $ youtube-dl --extract-audio --audio-format mp3   http://www.youtube.com/watch?v=O-xlvalecI8  [youtube] Setting linguistic communication [youtube] O-xlvalecI8: Downloading video webpage [youtube] O-xlvalecI8: Downloading video information webpage [youtube] O-xlvalecI8: Extracting video data [download] Destination: Give me crude inwards my lamp-O-xlvalecI8.flv [download] 100% of 11.73MiB inwards 00:32 [avconv] Destination: Give me crude inwards my lamp-O-xlvalecI8.mp3 Deleting master file Give me crude inwards my lamp-O-xlvalecI8.flv (pass -k to keep) 

The --audio-format parameter lets y'all specify the output well format. The inwards a higher house ascendency generates a mp3 file on your local difficult drive. Besides mp3, y'all tin specify other well formats such every bit wav. For detailed assistance close the parameters, run:

 $ youtube-dl --help
