Gentoo HD-vdr experimentel

Aktuelle Version vom 26. Februar 2010, 14:56 Uhr

[Bearbeiten] Beschreibung

Autor: Alexander Richter - 21.04.2008

Ich stelle hier eine Variante der Installation vor, die in einem Working System 64 Bit ( gentoo ) ein chroot erstellt, in dem die aktuellen Entwicklervarianten von ffmpeg xine-lib, xine-ui und vdr laufen können, ohne die Main Installation zu gefährden.

Der zusätzliche Platzaufwand beläuft sich auf rund 2 Gbyte. Backups des ganzen chroot-Umgebung sind ebenfalls möglich, was bei einer misslungenen Installation komfortabel ist.

[Bearbeiten] WRITE TODO

- lokales overlay im chroot anlegen
- im lokalen Overlay ffmpeg bauen
- im lokalen Overlay xine-lib bauen
- im lokalen Overlay xine-ui bauen
- im lokalen Overlay plugins bauen
- im lokalen Overlay patches einbinden

[Bearbeiten] Entwicklungsumgebung Hardware

- Amd Phenom 9500 auf Asrock AliveNF7G-Hdready
- 1x TT S3200
- 4 Gig Ram
- 24" Zoll Acer via 7050 Chipsatz des Boards

[Bearbeiten] Einrichten einer amd64-chroot Umgebung

[Bearbeiten] amd64-chroot Umgebung Vorbereitung und Betreten

- Verzeichnis anlegen, hineinwechseln : mkdir /vdr cd /vdr

- Stage entpacken : tar xfjpv stage3-amd64-2008.0_beta1.tar.bz2

- Portage tree entpacken tar xvjf portage-latest.tar.bz2 -C /vdr/usr

- mounten der benötigten Verzeichnisse ins chroot (Pfade zum chroot anpassen !)

#!/bin/bash
echo "mounting vs"
mount -o bind /dev /vdr/dev 
mount -o bind /dev/pts /vdr/dev/pts
mount -o bind /dev/shm /vdr/dev/shm
mount -o bind /proc /vdr/proc
mount -o bind /proc/bus/usb /vdr/proc/bus/usb
mount -o bind /sys /vdr/sys
mount -o bind /tmp /vdr/tmp
mount -o bind /usr/portage/distfiles /vdr/usr/portage/distfiles
# optional weitere
#mount -o bind /video /vdr/video
#mount -o bind /home/alex/mpeg2avi/ /vdr/home/alex/mpeg2avi/
#mount -o bind /home/alex/.vdrtransxvid/ /vdr/home/alex/.vdrtransxvid/
#mount -o bind /dev/sdb1/ /vdr/archiv/

- Xserver Zugang für Programme aus dem chroot ( hier xine )

$ xhost local:localhost 

- chroot

$ chroot /vdr

- im chroot System - Vorbereitung

env-update
source /etc/profile
export PS1="(chroot) $PS1"

- emerge --sync
- emerge --update world --deep
- emerge gentoo-sources ( selben Kernel wie außerhalb des chroot auswählen, wir wollen uns unseren eigenen DVB Treiber bauen, die müssen also zum "Außen" Kernel passen )

[Bearbeiten] s2-liplianin DVB Treiber im amd64-chroot per Hand installieren

cd /usr/local/src
hg clone http://mercurial.intuxication.org/hg/s2-liplianin/
cd s2-liplianin
cd linux/include/linux
ln -s /usr/src/linux-headers-`uname -r`/include/linux/compiler.h ./
cd ../../../
make
make install
depmod -a

[Bearbeiten] Alternativ Multiproto DVB Treiber im amd64-chroot per Hand installieren

( im chroot )

mkdir -p /data/installfiles/dvb
cd /data/installfiles/dvb

wenn noch nicht vorhanden

emerge mercurial 

hg clone http://jusst.de/hg/multiproto_plus
mv multiproto_plus/ dvb-multiproto_plus-cvs-17-04-2008

mkdir -p /usr/local/src/dvb 
cd /usr/local/src/dvb
cp -a /data/installfiles/dvb/dvb-multiproto_plus-cvs-17-04-2008/* .
make distclean

Link auf compiler.h setzen

cd /usr/local/src/dvb/linux/include/linux
ln -s /usr/src/linux/include/linux/compiler.h compiler.h

Kernelkonfiguration erstellen und abspeichern

cd /usr/src/linux
make menuconfig
Device Drivers  ---> Multimedia devices  ---> <M> DVB For Linux
"Exit"
"Exit"
"Exit"
Do you wish to save your new kernel configuration?
"Yes"

DVB Treiber installieren

cd /usr/local/src/dvb/
make && make install

Prüfen der DVB Treiber Installation

cd /lib/modules/$(uname -r)/kernel/drivers/media/dvb/ttpci
ls -l
-rw-r--r-- 1 root root  58888 Jan 29 19:36 budget-av.ko
-rw-r--r-- 1 root root  54424 Jan 29 19:36 budget-ci.ko
-rw-r--r-- 1 root root  35344 Jan 29 19:36 budget-core.ko
-rw-r--r-- 1 root root  33008 Jan 29 19:36 budget-patch.ko
-rw-r--r-- 1 root root  39112 Jan 29 19:36 budget.ko

-rw-r--r-- 1 root root  21416 Jan 29 19:36 ttpci-eeprom.ko

Bei Problemen auch : SUSE - Artikel , der Grundlage für diesen Part ist der Artikel OpenSUSE VDR DVB-S2 - Teil2: DVB Treiber

- im chroot System - dvb Treiber laden und Zugriffsrechte ändern, um als unprivilegierter User zugreifen zu können (hier mit TT S3200 und TT budget ci)

#!/bin/bash
echo "lade dvb-s2 kernel module"
modprobe stb6100
modprobe stb0899
modprobe stv0299
modprobe lnbp21
modprobe budget-ci
echo "ändere Zugriffsrechte des dvb Adapters 0" 
chmod a+rwx /dev/dvb/adapter0/demux0
chmod a+rwx /dev/dvb/adapter0/dvr0
chmod a+rwx /dev/dvb/adapter0/frontend0
chmod a+rwx /dev/dvb/adapter0/net0
echo "ändere Zugriffsrechte des dvb Adapters 1"
chmod a+rwx /dev/dvb/adapter1/ca0
chmod a+rwx /dev/dvb/adapter1/demux0
chmod a+rwx /dev/dvb/adapter1/dvr0
chmod a+rwx /dev/dvb/adapter1/frontend0
chmod a+rwx /dev/dvb/adapter1/net0
