• Recognises the interpret an title of the clip through OCR
• Synchronise the rcognition with the HTML page oof the broadcast
• ID3 tag creation
• Volume normalisation

Software requirements

• MPlayer
• lame
• libmpeg2
• normalize (optional)

Installation

For MPlayer see mplayer-plugin

To install libmpeg2

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

and normalise

cd $SOURCEDIR
tar -jxvf normalize-<VERSION>.tar.bz2
cd normalize-<VERSION>
./configure --prefix=/usr/local
make
make install

To compile savvy with libmpeg2 version 0.4.0 (mpeg2dec-0.4.0) the sources have to be patched.

The patch can be found here.

cd $SOURCEDIR
tar -xvzf savvy-<VERSION>.tgz
cd savvy.<VERSION>
zcat savvy.0.12b.diff.gz | patch -p1

In src/video.c line 602 has to be altered

- case -1:
+ case STATE_BUFFER:

Now, savvy should compile without errors

chmod 777 compile
./compile

Tip: It's important to decompress savvy in parallel to mpeg2dec-0.4.0, otherwise compile is to be adjusted

# Set this according to your folder containing the (compiled) libmpeg
mpeg2decFolder=../mpeg2dec-0.4.0
               ^^^^^^^^^^^^^^^^^

Configuration

Savvy is best started from within the reccmds.conf

 
Start savvy : /usr/local/bin/savvy.sh
Stop savvy? : killall savvy

For testing purposes one should make use of the commandline.

Settings are stored in settings. But there is not much to alter.

#Temporary data path (~double the size of the capture file is needed!)
