The script is:</p><p> </p><p>#!/bin/sh<br />### BEGIN INIT INFO<br /># Provides: set_ivtv_params<br /># Required-Start: $network<br /># Required-Stop: $network<br /># Default-Start: 2 3 5<br /># Description: Set IVTV Parameters to remove ghosting<br />### END INIT INFO<br /><br />case "$1" in<br />'start')<br /> /usr/bin/v4l2-ctl --set-ctrl temporal_filter=0 -d /dev/video1<br /> /usr/bin/v4l2-ctl --set-fmt-video=width=720,height=576 -d /dev/video1<br /> ;;<br />'stop')<br /> ;;<br />*)<br /> echo "Usage: $0 { start | stop }"<br /> ;;<br />esac<br />exit 0</p><p> </p><p>This works for me, I'm in a PAL region, you would need to adjust for NTSC.</p><p> </p><p>You can actually test it by running the script while watching a live tv program, when you run the script the ghosting will disappear.</p><p> </p><p>Regards,</p><p>Dave.<br /> </p>
