Mplayer video playing test

[hankgong]

We need to use A13 board to play video when GPIO is triggered. So I just wrote a simple script to test the capability of mplayer under the situation of kill and restart.

The script I wrote is pretty simple. Just start mplayer and sleep for a random delay and then kill it. And keep running this process as a indefinite loop.

#!/bin/bash

while true; do
    mplayer -fs -ao alsa:device=hw=0.0 /root/Attractor.mp4 </dev/null >/dev/null 2>&1 &
    sleep $(( ( RANDOM % 10 ) + 1 ))
    ps -ef | grep "mplayer" | awk '{print $2}' | xargs kill -9
done

However, I found that this loop will stop after several hours running and gave an strange error about Xkeyboard. However, when I start Xwindow, it didn't report this error.

XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect setup of xkeyboard-config.
         
Fatal server error:
Failed to activate core devices.

/root/stress.test.sh: line 7:  8213 Killed                  mplayer -fs -ao alsa:device=hw=0.0


Anybody can help me out of this? Thanks in advance...
