Shell script for burning events to CD-ROM

Baylink · Post by **Baylink** » Wed Jul 06, 2005 7:38 pm

I'm not entirely complete with this yet, but I'm posting it anyway because the hard 90% is done, and all that's left is the other 90%, with which I could use some help. :-)

Code: Select all

#!/bin/bash
# burnevents -- burn a CD with ZoneMinder event files on it
#
# Written Fri Jun 24 10:30:05 EDT 2005 by jra@microsys.us

# extract the events for a day, by default "yesterday", find the event directories
#  convert the JPEGs to a pair of MPEG's (which might be a bitch, since only certain
#  frames get analyze counterparts), and rename to Name-Timestamp(-analyze).mpg

# zeroth, set magic variables
ZMHOME=/appl/zm1211
MPEGDIR=/appl/zm1211/mpeg
CDRDEV=/dev/hdc
FFMPEG=
ZMPASS=mumble

# first, calculate yesterday
# YESTERDAY=`date -d "-1 day" +%Y-%m-%d`        # "normal": do yesterday
YESTERDAY=`date +%Y-%m-%d`                      # test: do today
STARTTIME="$YESTERDAY 00:00:00"
ENDTIME="$YESTERDAY 23:59:59"


# set -vx

cd $ZMHOME/events

mysql -u zm --password=$ZMPASS -D zm -B \
        -e "SELECT MonitorId,Id,Name FROM Events \
        WHERE StartTime > \"$STARTTIME\" and StartTime <= \"$ENDTIME\" \
        ORDER BY MonitorID,Id" | sed 1d |
while read MONITOR EVENT NAME
do
        pushd $MONITOR || continue      # skip the line without getting confused
                                        # if monitor directory not there

        pushd $EVENT || (popd;continue) # same thing for the event directory

        # Now, we're in the right place.  Grab the timestamp off the first jpeg,
        # then build the mpeg and name it appropriately

        TIMESTAMP=`date -r \`ls | head -1\` -Iminutes`

        echo ffmpeg -i %d-capture.jpg $MPEGDIR/$NAME-$TIMESTAMP.mpg
        ffmpeg $FFMPEG -i %d-capture.jpg $MPEGDIR/$NAME-$TIMESTAMP.mpg

        popd    # event dir
        popd    # monitor dir
done

# now burn them
cd $MPEGDIR
# mkisofs -rJ * | cdrecord -immed $CDRDEV

# and remove them.
mv * archive/

Clearly, I'm not entirely done with it -- I haven't gotten to tuning the burning commands yet because I haven't quite figured out what to tell ffmpeg to get Windows-playable video files that the users will be able to navigate around in. This machine is on-net at the moment, but they don't necessarily need it to be, and the wireless (only practical option) is being cranky.

So, first, any suggestions on $FFMPEG?

Once I get that done, I'll look into how hard doing a companion clip with the analysis frames will be; annoying, I suspect (involving making symlinks for all analyze frames that don't exist)...

I seem to reply to myself a lot around here...

After extensive debugging, I seem to have a *very* strange problem with my script, which now looks like this:

Code: Select all

#!/bin/bash
# burnevents -- burn a CD with ZoneMinder event files on it
#
# Written Fri Jun 24 10:30:05 EDT 2005 by jra@microsys.us

MPEGDIR=/appl/recordings/mpeg
CDRDEV=/dev/hdc

# first, calculate yesterday
# YESTERDAY=`date -d "-1 day" +%Y-%m-%d`        # "normal": do yesterday
YESTERDAY=`date +%Y-%m-%d`                      # test: do today
STARTTIME="$YESTERDAY 00:00:00"
ENDTIME="$YESTERDAY 23:59:59"


# set -vx

cd $ZMHOME/events

mysql -u zm --password=zomeminter -D zm \
        -e "SELECT MonitorId,Id,Name FROM Events \
        WHERE StartTime > \"$STARTTIME\" and StartTime <= \"$ENDTIME\" \
        ORDER BY MonitorID,Id" | sed 1d |
while read xMONITOR xEVENT xNAME
do
        # Sign on
        echo "Processing $xMONITOR/$xEVENT/$xNAME" >&2

        # check to make sure the event directory exists, or skip the event
        [ -d "$xMONITOR/$xEVENT" ] || {
                echo "=== Skipping $xMONITOR/$xEVENT -- no directory ===" >&2
                continue
        }
        cd $xMONITOR/$xEVENT

        # Now, we're in the right place.  Grab the timestamp off the first jpeg,
        # then build the mpeg and name it appropriately
        TIMESTAMP="`date -r \`ls | head -1\` -Iminutes`"

        CLIPNAME="${MPEGDIR}/${xNAME}-${TIMESTAMP}.mpg"
        echo "Processing $xMONITOR/$xEVENT/$xNAME" >&2

        ffencode $CLIPNAME
        echo "Processing $xMONITOR/$xEVENT/$xNAME" >&2

        cd ../..
        echo >&2

        sleep 2
done

# now burn them
cd $MPEGDIR
#mkisofs -rJ * | cdrecord -immed $CDRDEV

# and remove them.
#mv * archive/

and ffencode is just

Code: Select all

ffmpeg -vcodec msmpeg4 -acodec mp3 -r 3 -i %05d-capture.jpg $1

and in case anyone's wondering *why* that is in a subscript, it's because the main script's loop breaks if I call ffmpeg from it. Even if I call it from a subscript. If I comment out the call, it counts through the event info returned to the while loop from mysql just perfectly. If I call ffmpeg, then that stream of data gets screwed up, dropping some lines completely, and others partially.

I, and my shell programmer cow-orker, are both flummoxed. This is the Last Bug; anyone got any ideas?

Incidentally, even when the data gets hosed, those second and third "echo Processing" statements both return the same thing.

Hey

This looks mighty useful, have you managed to find a fix at all?

I don't need the cd writing part, but the rest would be most useful.

Cheers!

Is the above script working yet ?.

I have tried the

ffmpeg -vcodec msmpeg4 -acodec mp3 -r 3 -i 001-capture.jpg

line by itself to encode 1 jpg to mpg and just get

001-capture.jpg unknown format.

there's something wrong but i cant understand what in your script made this

for ffmpeg command i prefer this:

$FFMPEG -y -r 2.19 -i %04d-capture.jpg -s 480x360 -r 25 $MPEGDIR/$NAME-$TIMESTAMP.mpg
