create a cron job to kill process if stuck for x number of hours - Linux

Hello, We have a mplayer process which sometimes hangs for several hours or days until killed. We would like to create a cron job that runs every hour to kill these stucked mplayer process if they have been running for more than X number of hours. A sample stucked mplayer process is: root@debian:~# ps -o etime,pid,stime,time,cmd -C mplayer ELAPSED PID STIME TIME CMD 7-13:38:20 30306 Jul29 7-12:47:28 mplayer /storage/cgi-bin/uploads/00450/nnyb38w2tdqj -identify -frames 0 -quiet -ao null -vo null This project is to create the script that will be run via cron job. It will check to see if there are any mplayer process stucked for more than X number of hours and kill if so. Budget is about $40 Thank you.
