Compilation vTuner for Raspberry Pi (RPi) Raspbian.

Raspbian doesn't provide an out-of-the-box package with linux-headers so we need to build our own.
I find this thread that help me a lot:

https://www.grendelman.net/wp/compiling ... pberry-pi/

Code: Select all

cd
wget --no-check-certificate https://www.grendelman.net/files/raspi/Module.symvers


Installing compilation environment:

Code: Select all

sudo apt-get update
sudo apt-get -y install build-essential mercurial cvs subversion libncurses-dev
sudo apt-get -y install cmake dialog autoconf libtool flex gettext


Thoses packages are enough to complete this tuto, tested on this image:
http://downloads.raspberrypi.org/images ... spbian.zip

Please be carefull the value: c6851e9 (see below) is changing daily so you need to adapt it towards the value that you will get when following this tuto.

Code: Select all

cd /usr/src
sudo wget -O raspberrypi-linux-`uname -r`.tar.gz https://github.com/raspberrypi/linux/tarball/rpi-patches
sudo tar xvzf raspberrypi-linux-`uname -r`.tar.gz
sudo ln -s /usr/src/raspberrypi-linux-c6851e9 /lib/modules/`uname -r`/build
cd /usr/src/raspberrypi-linux-c6851e9
sudo sh -c 'zcat /proc/config.gz  > .config'
sudo sed -i 's/EXTRAVERSION =.*/EXTRAVERSION = +/' Makefile
sudo cp ~/Module.symvers .
sudo make oldconfig
sudo make modules_prepare


Create a symlink to allow stressless vtuner compilation.

Code: Select all

sudo ln -s /usr/src/raspberrypi-linux-c6851e9/ /usr/src/3.1.9+
cd
hg clone https://code.google.com/p/vtuner.linux-driver/


Compiling and installing the kernel driver:

Code: Select all

cd vtuner.linux-driver
make clean
make
modinfo vtunerc.ko
sudo mkdir /lib/modules/`uname -r`/misc
sudo cp vtunerc.ko /lib/modules/`uname -r`/misc
sudo depmod -a
sudo rmmod vtunerc
sudo modprobe vtunerc


Giving lower access right to dvb device:

Create a file: /etc/udev/rules.d/15-dvb.rules

Containing:

Code: Select all

sudo nano /etc/udev/rules.d/15-dvb.rules


SUBSYSTEM=="dvb", ACTION=="add", MODE="0666"

Building the vtuner applications:

Code: Select all

cd
hg clone https://code.google.com/p/vtuner.apps/
cd vtuner.apps


Create the file ~/vtuner.apps/Make.config as follow:

Code: Select all

nano ~/vtuner.apps/Make.config


# define the CC for target arm
CC-arm=gcc
STRIP-arm=strip
INCLUDE-arm=-I/usr/src/3.1.9+

In order to have vtuner properly compiled you need to define the file ~/vtuner.apps/build/arm/Makefile as follow:

Code: Select all

mv ~/vtuner.apps/build/arm/Makefile ~/vtuner.apps/build/arm/Makefile.ori
nano ~/vtuner.apps/build/arm/Makefile


Code: Select all

ARCH=arm
-include ../../Make.config

CC=$(CC-$(ARCH))
CXX=$(CXX-$(ARCH))
CFLAGS=-fPIC -DHAVE_DVB_API_VERSION=5 $(INCLUDE-$(ARCH)) $(DBGFLAGS)
LDFLAGS=-lpthread -lrt
DRIVER=vtuner-dvb-3
STRIP=$(STRIP-$(ARCH))

all: ../../dist/$(ARCH)/vtunerd.$(ARCH) ../../dist/$(ARCH)/vtunerc.$(ARCH)
   $(STRIP) ../../dist/$(ARCH)/vtunerd.$(ARCH) ../../dist/$(ARCH)/vtunerc.$(ARCH)
   

-include ../../Make.rules
   
vtuner-dvb-3.o: ../../vtuner-dvb-3.c ../../vtuner-dvb-3.h
   $(CC) $(CFLAGS) -c -o vtuner-dvb-3.o ../../vtuner-dvb-3.c



With the default one only vtunerd.arm is compiled, we don't have vtunerc.arm and vtunerc.arm is the file that we need.

Starting compiling

Code: Select all

cd
cd ./vtuner.apps
make -C ./build/arm/ all


Resulting files will be in: ~/vtuner.apps/dist/arm/

And be called: vtunerc.arm and vtunerd.arm

If you follow this tuto from the beginning you are now able to call vtunerc to attach to your NessieDVB tuners:

Code: Select all

sudo ~/vtuner.apps/dist/arm/vtunerc.arm -f S2

In attachement you will find the executable files mentionned in this post (for people that don't want to compile) and the configuration files used for the compilation.

This is very interesting post. I've already (today) ordered RPI to test it - I hope I'll test it within 2 weeks.

The Makefile looks ok, I think it was not intended from original author to have vtuner client on arm CPU.

Once more, great work

Hi,

Thanks I should make some tests now to see if compilation is really working as expected.
The problem with the RPi is that they didn't licence MPEG-2 on it, so unfortunately there is no MPEG-2 hardware decoding (even if the hardware is capable of).

Mebepi

P.S.: I hope that you order yours from Farnell/element 14 because RS has a huge backlog.

Please check if you are using vtuner driver 1.2p3 which has memory leak fix built-in.

The problem with the RPi is that they didn't licence MPEG-2 on it, so unfortunately there is no MPEG-2 hardware decoding (even if the hardware is capable of).

Is it the same valid for h264 decoding as well? I gues so, unfortunatelly.

Hi,

About the driver I use the one in the main branch (like described in the tutorial), so if I need to used another source/sub-branch please let me know. The tuto is the exact description on how I build vTuner driver and apps.

And about raspeberry.org, they pay licences for MPEG.4 and X.264 but not MPEG-2.

No no, the source is correct. I only wanted to note that some fresh patch
was added there lately, so the repo update is recommended.

Yeh, nice step-by-step. Thanks for you work.

And about raspeberry.org, they pay licences for MPEG.4 and X.264 but not MPEG-2.

I just found some software-based solution, what is, of course,
not what we need. I don't think it can be decoded fast enough.

Hi,

Great news! We can purchase a MPEG-2 licence now for our Raspberry Pi.

Mebepi

Oh, it is really great news!

Can you show me how much the MPEG2 license will cost?

Thx.

License for MPEG-2 decoding costs 2.40 UKP. After paying the license with PAYPAL key arrived within one hour into my email box.

So I've tested raspberry PI with vtuner driver acnd client. It works, but problems are with CPU - it seems not to be strong enough to display and decode HD channels.

As I've done many test the best solution seems to be:
latest XBian (0.7.1 - see http://forum.xbian.org/viewtopic.php?f=13&t=1182)
compiled vtunerc.ko and vtunerc.arm (I'm adding binaries for kernel 3.2.27+ for other enthusiasts)
vdr + streamdev plugin compiled inside RPI (I've used vanilla vdr-1.7.27 and vdr-streamdev 0.6.0 from http://projects.vdr-developer.org/proje ... mdev/files) - no patches
This combination was able to receive SD channels without problems.
