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):

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/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):

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
