Software requirements

  • FFMPEG

Installation

Basic (including FB/Xv support)

FFMPEG

cd $SOURCEDIR
tar xvzf ffmpeg-<VERSION>.tar.gz
cd ffmpeg-<VERSION>
./configure --prefix=/usr/local \
            --enable-shared
make
make install
ldconfig

For deinterlacing pp-filters in recent plugin versions, FFMPEG needs some additional options at compile time

cd $SOURCEDIR
tar xvzf ffmpeg-<VERSION>.tar.gz
cd ffmpeg-<VERSION>
./configure --enable-shared \
            --enable-pp \
            --enable-gpl
cd libavcodec/libpostproc
make
mkdir -p /usr/local/include/postproc
install -m 644 postprocess.h /usr/local/include/postproc/postprocess.h
cp libpostproc.a /usr/local/lib
cd -
make
make install
ldconfig

DirectFB support

DirectFB

cd $SOURCEDIR
tar xvzf DirectFB-<VERSION>.tar.gz
cd DirectFB-<VERSION>
./configure --help (für den passenden driver ???)
./configure --prefix=/usr/local \
            --with-gfxdrivers=???
make
make install

DFB++

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

Check the HOWTO for enabling hardware MPEG-2 decoding support in motherboards with CLE266 chipset [1]. This reduces CPU load from ~70% to ~30% on 1GHz EPIA board.

Vidix support

Vidix

cd $SOURCEDIR
tar xvzf vidix-cvs.tar.gz
cd vidix
./configure --prefix=/usr/local
make
make install
ldconfig

See plugin installation

Im Makefile muss eingestellt werden, welche Treiber-Variante man benutzen will und wo sich die benötigten Bibliotheken / Headerfiles befinden.
