Firstly... if anyone out there with the know how wants to improve what I've done, be my guest! I've spent a few weeks teaching myself how to use ubuntu just so I can get this great zoneminder program up and running (and I'm extremely impressed with it!).
Ok, what I've done:
Zoneminder will now create an avi each time an event is detected. It will place this avi in a pre-determined spot (say /media/videos) and rename the avi to include the camera id and time the file was created.
How to do it:
- Firstly, use the provided 'filter' option in the zoneminder web gui and create the following:
- Edit zmvideo.pl (sudo updatedb && locate zmvideo.pl to find this file... it should be located in /usr/bin)
- sudo vim /usr/bin/zmvideo.pl (which will open zmvideo.pl in a text editor)
- type ":set number" and locate line number 324
- Replace this line with the following:
Code: Select all
my $command = ZM_PATH_FFMPEG." -y -r $frame_rate ".ZM_FFMPEG_INPUT_OPTIONS." -i %0".ZM_EVENT_IMAGE_DIGITS."d-capture.jpg -s $video_size ".ZM_FFMPEG_OUTPUT_OPTIONS." '/media/500gig/cctv_mpegs/$video_file' > ffmpeg.log 2>&1";
)- Save and exit the file
- cd $HOME && sudo vim RenameVideo (will create an empty text file)
- paste the following code in:
Code: Select all
#! /bin/bash
# Set this value to the zoneminder 'events' folder
EVENTS="/media/500gig/zoneminder/events"
# Set this to where the event videos are saved
MPEGS="/media/500gig/cctv_mpegs"
cd $MPEGS
for FILE in `find Event*`; do
TIMESTAMP=`ls -l --time-style=+%Y-%m-%d-%H-%M-%S $FILE | cut -d' ' -f6`;
NAME=`echo $FILE | cut -d'-' -f2`
cd $EVENTS
OWNER=`find * -type d | grep $NAME | cut -d'/' -f1`
cd $MPEGS
# 1 = camera 1, check the events folder for camera id
if [ "$OWNER" = "1" ]; then
CAMERA="CAMERA_1"
# 2 = camera 2, check the events folder for camera id
elif [ "$OWNER" = "2" ]
then
CAMERA="CAMERA_2"
# 3 = camera 3, check the events folder for camera id
elif [ "$OWNER" = "3" ]
then
CAMERA="CAMERA_3"
# 4 = camera 4, check the events folder for camera id
elif [ "$OWNER" = "4" ]
then
CAMERA="CAMERA_4"
else
echo "not associated with a camera"
fi
FILENAME=$TIMESTAMP"_"$CAMERA".avi"
if [ `ps -A | grep ffmpeg | cut -d' ' -f12` = "ffmpeg" ]; then
echo "ffmpeg encoding, will not rename $FILE at this time"
else
`mv $FILE $FILENAME`
fi
done
- chmod +x RenameVideo (makes the file executable)
- sudo crontab -e
- add the following:
*/1 * * * * sudo $HOME/RenameVideo >/dev/null 2>&1
This will allow the RenameVideo script to check for video files each minute, renaming them as necessary. The script will need sudo access to run with appropriate permission therefore you also need to do the following (*NOTE, this will allow administrator permissions for this script, which may completely destroy your entire system... make sure you understand what you are trying before attemping the following):
- sudo visudo
- At the bottom, add "%username ALL=(ALL) NOPASSWD:/$HOME/RecordingVideo" (where username is your username)
With any luck, your script will work and the end result should look something like this:
mediabox@mediabox:/media/500gig/cctv_mpegs$ ls
2009-02-19-22-40-32_CAMERA_1.avi 2009-02-20-04-45-24_CAMERA_1.avi 2009-02-20-08-52-52_CAMERA_2.avi 2009-02-20-13-08-36_CAMERA_1.avi ... you get the idea
Now I can watch all motion created on any comp/xbmc setup in the house, all thanks to zoneminder!
