Noad

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.

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

Run noad                         : /usr/local/bin/noad.sh -start
Run noad, all recordings (batch) : /usr/local/bin/noad.sh -batch
View Cut list                    : /usr/local/bin/noad.sh -view
In prozess                       : /usr/local/bin/noad.sh -count
Stop noad (killpid)              : /usr/local/bin/noad.sh -killpid
Stop noad (killall)?             : /usr/local/bin/noad.sh -killall
Remove all marks                 : /usr/local/bin/noad.sh -marks.vdr
Remove all pids                  : /usr/local/bin/noad.sh -noad.pid

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.
