Keep a copy of the raw Youtube FLV,MP4,etc stored in /tmp/

lsof -n -P|grep FlashXX|awk '{ print "/proc/" $2 "/fd/" substr($4, 1, length($4)-1) }'|while read f;do newname=$(exiftool -FileModifyDate -FileType -t -d %Y%m%d%H%M%S $f|cut -f2|tr '\n' '.'|sed 's/\.$//');echo "$f -> $newname";cp $f ~/Vids/$newname;done
Certain Flash video players (e.g. Youtube) write their video streams to disk in /tmp/ , but the files are unlinked. i.e. the player creates the file and then immediately deletes the filename (unlinking files in this way makes it hard to find them, and/or ensures their cleanup if the browser or plugin should crash etc.) But as long as the flash plugin's process runs, a file descriptor remains in its /proc/ hierarchy, from which we (and the player) still have access to the file. The method above worked nicely for me when I had 50 tabs open with Youtube videos and didn't want to have to re-download them all with some tool.

  • Newer versions of the flashplayer browser plugin delete the tmp flash video immediately after opening a filehandle to prevent the user from "exporting" the video by simply copying the /tmp/FlashXYZ file. This command searches such deleted flash videos and creates symbolic links to the opened filehandle with the same name as the deleted file. This allows you to play your flash-videos (from e.g. youtube) with e.g. mplayer or copy the buffered video if you want to keep it. Show Sample Output

    for h in `find /proc/*/fd -ilname "/tmp/Flash*" 2>/dev/null`; do ln -s "$h" `readlink "$h" | cut -d' ' -f1`; done

  • Alias to play flash videos with mplayer. You can replace mplayer with your favorite video player. This alias supports Chrome & Firefox's way of handling the flash plugin. It will play all the videos in the cache. Note that certain videos might never make it to the cache, if the publisher ask for them not to: they will just be loaded in RAM. A variant if you're just interested in playing the audio, for example for a music : alias flashmusic="mplayer -vo null \$(find /proc/\$(pgrep -f 'libgcfl|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"

    alias flashplay="mplayer \$(find /proc/\$(pgrep -f 'libgcflash|libflashplayer')/fd/ -printf '%p %l\n' |grep FlashXX | cut -d\ -f1)"

What Others Think

In my tests, `exiftool` didn't find any tags containing a video title. So instead "FileModifyDate" is used as the basis of the filename. It would have been nice to at least use "MediaModifyDate", but only MP4s seemed to support that.
