Script to create jpg thumbnails from flv files using ffmpeg

Using instructions from Using ffmpeg to create jpg thumbnails from flv files,

I created a bash script that would take a filename from the command line, then output the file with a .jpg extension.

The command line that was given in the post didn't work for me:
ffmpeg -i video.flv -an -ss 00:00:03 -an -r 1 -vframes 1 -y %d.jpg

But, the one given in the comment by Philippe Maegerman did (-minus the .exe part):
ffmpeg.exe -i stream_1146848749371.flv -y -f singlejpeg -ss 0.001 -vframes 1 -an test.jpg

I just modified it to suit my needs.

Some SunRay clients show 14D
Every once in awhile, some SunRay clients will stop being able to connect to a SunRay session and only display 14D.

Log messages showed:
Oct 27 18:18:39 minsk utauthd: Worker4 NOTICE: SESSION_OK pseudo.00144f6f741c
Oct 27 18:18:39 minsk utdevmgrd[19170]: symlink No such file or directory: /tmp/SUNWut/units/IEEE802.00144f6f741c

According to this article:
The SRSS software creates some directory and files in the /tmp filesystem. RedHat Linux has a cron job cleaning up /tmp daily. After a few days some of the files from SRSS were removed, causing the problem. This can be solved by adding "-x /tmp/SUNWut" to /etc/cron.daily/tmpwatch
