Youtube Streamed Video on Local Disc

I always need to find the Cache of streamed media including youtube’s video in WebM format. Here is my environment

• Firefox 16.0.2
• Ubuntu 12.04.1 LTS

There’re two types of YouTube cache in local directory.

1. WebM
2.  Macromedia Flash Video

Here I done with the HTML5 but for Flash , the trick is more similar.

Two possible trail and error way you can find the videos:

1. Locate the WebM cache file (For most medium sized HTML5)

   yt(){
           # HTML 5
           find ~/.mozilla/firefox/*.default/ -type f -size +100k -ls|awk '{printf $11 "\n"}'|xargs file|grep -i webm|awk -F: '{printf $1 "\n"}'
   
           # Flash Video
           find ~/.mozilla/firefox/*.default/ -type f -size +100k -ls|awk '{printf $11 "\n"}'|xargs file|grep -i 'Flash Video'|awk -F: '{printf $1 "\n"}'
   
   }

2. Locate mozilla-media-cache/media_cache (deleted) (For bigger size video)

yt2(){

        # This shows mozilla-media-cache/media_cache (deleted) which is cache of HTML5
        FX='';
        FX=`ps -ef|grep '/usr/lib/firefox/firefox'|grep -v grep|head -1|awk '{printf $2}'`
        if [ $FX != '' ] ; then {
                echo /proc/$FX/fd/;
                ll /proc/$FX/fd/|grep media_cache
        }   
        else echo 'No running firefox';return 0;  
        fi; 

}

Just copy that file to desired location.Enjoy the video in VLC offline.Hope this helps!
