Overview

This project was developed for air monitoring, video reports (on DVD media) preparation.

Software complex consists of two parts

1. PVR - video recorder, video preview and audio level monitoring, rotating recorded video (delete older parts to keep spool size in fixed size).
2. web-oriented application for DVD building.

Hardware requirements

PVR uses video capture card with hardware MPEG-2 encoder (see ivtv projects for details).

Recorder MPEG-2 stream saved to hard disk, the large disk space - the more video could be saved. :-))

DirectFB is used for GUI.

Downloads

Current version 1.0 (-r42):

airrec-1.0-r42.tar.bz2 - source code

Build

1. Download source code from link above and unpack.

cd /usr/local/src
wget http://research.m1stereo.tv/downloads/airrec/airrec-1.0-r42.tar.bz2
bzip2 -cd airrec-1.0-r42.tar.bz2 | tar xvf -

2. Make sure that installed additional packets:
- DirectFB-devel
- sqlite-devel-3.1.2-3
3. Go to source code dir and compile

cd airrec
cd src
make

If DirectFB was installed from rpm you need fix INCLUDES variable in Makefile.

Install

1. Directory structure preparation:
- /opt/airrec - programs and scripts dir.
- /var/spool/airrec/live - directory for db file and live streams.
- /var/spool/airrec/live/ch0 - directory for saving MPEG-2 fragments for channel 0.
- /var/spool/airrec/dvd/master - built dvd storage
- /var/spool/airrec/dvd/temp - temparatiry storage for dvd building.
2. Copying files:

#main executable
cp /usr/local/src/airrec/src/airrec /opt/airrec

# database file for storing info about fragments
cp /usr/local/src/airrec/src/airrec.db /var/spool/airrec/live

# mpeg coder setup scripts and srt file making scripts
cp /usr/local/src/airrec/scripts/airrec_srt_creator.pl /opt/airrec
cp /usr/local/src/airrec/scripts/airrec_srt_watcher.sh /opt/airrec
cp /usr/local/src/airrec/scripts/ivtv.setup.CODEC.sh /opt/airrec
cp /usr/local/src/airrec/scripts/ivtv.setup.INPUT.sh /opt/airrec

Configure

1. Configuration file for recorder (sample, 1 channel, 2x80GB stripe for video storing):

db-file=/var/spool/airrec/live/airrec.db
use-channel=0
ident="M1 [main]"
dev-pcm=/dev/video24
dev-yuv=/dev/video32
dev-mpeg=/dev/video0
spool=/var/spool/airrec/live/ch0
spool-limit=140000
#noflip
vsync=25
syslog=6

Some parameters explanations:

- db-file=<filename> - database file name for storin info about fragments
- fb-mode=<mode str> - Setup FrameBuffer mode ( default "1024,768,32")
- use-channel=<N> - Activate channel N and apply further options to that channel
- ident=<N> - Channel ident
- dev-pcm=<filename>
- dev-yuv=<filename>
- dev-mpeg=<filename>
- spool=<PATH> - Location where mpg file stored
- spool-limit=<N> - Limit stored spool to <N> Megabytes
- vsync=<N> - Try to redraw screen at <N> fps.
- noflip - Disable surface flipping mode.
- config=<filename> - Use config file.
- syslog=<N> - Use LOG_LOCAL<N> facility for syslogging.

2. Running recorder preparation:
- 1. /etc/crontab (rotating and srt's creating/cleanup):

-- skipped --
0,5,10,15,20,25,30,35,40,45,50,55 * * * * root /usr/bin/killall -HUP airrec
0,20,40 * * * * root /opt/airrec/airrec_srt_watcher.sh
--skipped--

- 2. /etc/modprobe.conf:

-- skipped --
alias char-major-81 videodev
alias char-major-81-0 ivtv
options ivtv pal=D cardtype=15
#options i810fb vram=8 xres=1024 bpp=32 yres=768 hsync1=30 hsync2=55 vsync1=55 vsync2=72 accel mtrr
--skipped--

- 3. /etc/rc.d/rc.local (init matrox's module / codes setup):

-- skipped --
# setup new io scheduler
echo -n "cfq" > /sys/block/hda/queue/scheduler
echo -n "cfq" > /sys/block/hdc/queue/scheduler
echo -n "cfq" > /sys/block/hdd/queue/scheduler

# airrec init
/sbin/modprobe drm
/sbin/modprobe mga
/sbin/modprobe matroxfb_base
/opt/airrec/ivtv.setup.CODEC.sh
/opt/airrec/ivtv.setup.INPUT.sh
/bin/sleep 2
--skipped--

- 4. /etc/inittab (start at the first console)

-- skipped --
# Run gettys in standard runlevels
#1:2345:respawn:/sbin/mingetty tty1
1:2345:respawn:/sbin/startsess tty1 /opt/airrec/airrec -c /opt/airrec/airrec.conf.mga >/dev/null 2>/dev/null
--skipped--

- 5. /etc/directfbrc :

no-vt-switch
#no-vt-switching
#no-vt

- 6. /etc/hotplug/blacklist (preventing loading mga video board drivers at boot stage)

-- skipped --
