Description

NoAd is a program for commercial detection in vdr recordings. It uses several characteristics of the film, like station logos and AC3 sound, for the detection and produces cutting marks for the recording.

Hardware requirements

Software requirements

  • libmpeg2
  • ImageMagick (optional)

Installation

First install libmpeg2

cd $SOURCEDIR
tar xvzf mpeg2dec-<VERSION>.tar.gz
cd mpeg2dec-<VERSION>
./configure --prefix=/usr/local
make
make install

Now you can install NoAd an usual

cd $SOURCEDIR
tar jxvf noad-<VERSION>.tar.bz2
cd noad-<VERSION>
./configure --with-mpeginclude=/usr/local/include/mpeg2dec
make
make install

NoAd needs write access to the video directory!

Configuration

It's best to start NoAd through the reccmds.conf. So Add the following lines

Start advertising filter      : /usr/local/bin/noad.sh start
View Cut list                 : /usr/local/bin/noad.sh marks
Advertising filter overview   : /usr/local/bin/noad.sh count
Stop advertising filter       : /usr/local/bin/noad.sh stop
Stop all advertising filters? : killall noad

Parameter

Parameter (short) Parameter (long) Description
-s --statisticfile name of the file for statistic-data
-v --verbose increments the log-level, can be given multiple
-b --background start noad as backround-process
-p --priority priority when running as background-process [20...-20] default is 20
-c --comments adds comments to the marks in marks.vdr
-o --overlap try to detect repeating sequences before and after the break
-a --ac3 experimentel: use ac3-sound for ad-detection
-j --jumplogo looks for vertikac drifted logos
-O --OSD sends an OSD-Message to the running VDR-instance(localhost:2001) for Start and End
-S --savelogo saves the detected logo for later usage
-B --backupmarks saves an exsiting marks.vdr to marks0.vdr
-n --nelonen special behavior for finish stations
-V --version shows the Version and exits

Tips

After using NoAd to mark all commercials in a recording one shouldn't use the cutting function of VDR blindly. NoAd is not perfect and the telestation do some nasty things with there logos. So it's always better to look manually over the cutting marks before really cutting.
