[HowTo] Save all flash video files being played in Chrome/Chromium to Home directory

After watching a video on youtube in chrome, I felt like saving it. I couldn’t find the flv in ~/.cache or in /tmp. So I dug around and found this link: http://superuser.com/questions/235535/in-google-chrome-on-linux-where-is-the-flv-if-not-in-tmp.

The solution by omab worked for me. So I wrote this one line command which would save all the currently playing files in Chrome and Chromium in home directory.

A=`ps auwx | grep "flash" | grep "chrom" | awk '{print $2}'`; ls -la /proc/$A/fd | grep Flash | awk '{print $8}' | xargs -I _ mplayer /proc/$A/fd/_  -dumpstream -dumpfile ~/_.flv
