With the DXR3 plugin one can use DXR3/Hollywood+ cards as output devices for VDR. The bargain of a costly FullFeatured DVB card can be avoided.

Hardware requirements

• DXR3/Hollywood+

Software requirements

• em8300 driver
• FFMPEG
• Linux kernel sources

Installation

To install FFMPEG

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

Now the kernel sources has to be installed for the em8300 driver which is installed after it. If a normal release is used

cd $SOURCEDIR
tar xvzf em8300-<VERSION>.tar.gz
cd em8300-<VERSION>
./configure --prefix=/usr/local
make
make install
cd modules
make
make install
make devices

if the CVS version (recommended) is used

cd $SOURCEDIR
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/dxr3 login
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/dxr3 co em8300
cd em8300/modules
make
make install

cd ../em8300setup
gcc em8300setup.c -o em8300setup -I../include
cp em8300setup /usr/local/bin

Patches

Before the plugin is installed after plugin installation, the plugins Makefile has to be adapted

- DVBDIR = ../../../../DVB
+ DVBDIR = ../../../DVB

- FFMDIR = ../../../../ffmpeg
+ FFMDIR = /usr/local/include/ffmpeg

Problems

• There are incompatibilities in combination with ac3overdvb-patch and a channels.conf with DD-Audio-Pids
• The em8300 driver release cannot be compiled under SuSE 9.1, the CVS version has no problem.
• CVS HEAD version of plugin does not support OSD menu, use the vdr-dxr3-0-2 branch instead.
• The OSD is rather limited in functionality compared to a DVB card with onboard MPEG2 decoder. This makes it impossible to use plugins such as osdimage and osdpip. There have been lots of improvements to this in the vdr-dxr3-0-2 branch in CVS recently, though.
• Some people reported unstability and flicker OSD problem with this plugin. Using skinelchi-plugin instead the default one usually helps.

CVS

First, login to CVS:

cvs -z3 -d:pserver:anonymous@dxr3plugin.cvs.sourceforge.net:/cvsroot/dxr3plugin login

Then, check out the DXR3 plugin sources. At the moment, using the version in the vdr-dxr3-0-2 branch is recommended; CVS HEAD/MAIN is not ready for general consumption yet. To check out the vdr-dxr3-0-2 branch:

cvs -z3 -d:pserver:anonymous@dxr3plugin.cvs.sourceforge.net:/cvsroot/dxr3plugin co -r vdr-dxr3-0-2 dxr3

The adventurous may check out the MAIN branch with:

cvs -z3 -d:pserver:anonymous@dxr3plugin.cvs.sourceforge.net:/cvsroot/dxr3plugin co dxr3
