[linux-dvb] Re: How to watch DVB-t TV (or 'am I wasting my time?')

[Scott White <scott@clubguide.com>]

Hay Matthew,

It is possible.  I have done it.  Ever heard the expression, "standing
on the shoulders of giants."  Here is a how-to I wrote after everybody
else had done all the work getting it going.

Enjoy

Here are the steps I took to get the Hauppauge Nova-T working on RedHat
7.2  This is all everybody else's hard work, I'm just getting it down
before I forget. 

My system is a stock RedHat 7.2 system.  A custom install, including the
kernel source, development utilities etc.   I downloaded all the RedHat
errata updates including the latest kernel and kernel source RPMs from
ftp://ftp.mirror.ac.uk/sites/ftp.redhat.com/pub/redhat/linux/updates/7.2/en/os and applied them with rpm -Fvh *.rpm.  I am a gnome user, so I then downloaded and ran the Ximian Desktop installer from http://www.go-gnome.org.  Finally I run Redcarpet, which comes as part of Ximian Desktop periodical to make sure all my packages keep up to date. 

This assumes you are logged in as a user who has write access to
/usr/local/src and has /usr/local/bin in their path.


1)  Prepare the Kernel Source 

RedHat puts the Kernel source in /usr/src/Linux-2.4 and puts a .config
appropriate to your system in that directory.  Just to get everything in
order - 

cd /usr/src 
ln -s linux-2.4 linux 
cd linux 
make dep && make && make modules 

( No make install, trying to stay in line with distribution ) 


2) Download the DVB cvs 

I'm going to use /usr/local/src to collect together the various parts I
need. Download the DVB cvs from linuxtv.org 

cd /usr/local/src 
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv login 
Just press enter at the password prompt 
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv co DVB 

This creates a DVB directory in /usr/local/src 


3)Compile and install the DVB driver as per the docs 

cd DVB/driver 
make 
make install 
PATH=$PATH:/usr/sbin:/sbin (if you have not already got it)
su -c "make insmod"

No errors, all cool. 

Quick check of lsmod

cd /usr/local/src/DVB/libdvb 
make 
su -c "make install"

PLACE HOLDE _MODULES.CONF


4) Download and install DVBtune from linuxstb.org 

First install libxml v2

cd /usr/local/src
ncpftpget
ftp://ftp.gnome.org/pub/GNOME/stable/redhat/i386/libxml/libxml2-2.4.13-1.i386.rpm
ncpftpget
ftp://ftp.gnome.org/pub/GNOME/stable/redhat/i386/libxml/libxml2-devel-2.4.13-1.i386.rpm
rpm ivh libxml2-2.4.13-1.i386.rpm libxml2-devel-2.4.13-1.i386.rpm

wget http://www.linuxstb.org/dvbtune/dvbtune-0.1.tar.gz
tar xvfz dvbtune-0.1.tar.gz
cd dvbtune-0.1

you need to change the first line of the make file to include your new
xml libraries 

INCS=-I ../DVB/ost/include -I /usr/include/libxml2

make
su -c "cp dvbtune xml2vdr /usr/local/bin; chmod 755
/usr/local/bin/dvbtune /usr/local/bin/xml2vdr"


5) Time to try tuning 

First use the XML feature of dvbtune to check out your aerial.

cd  /usr/local/src/dvbtune-0.1/scripts
edit scan_uk-t.sh to add your frequencies, if you don't use the Crystal
Palace transmitter.  You will probably need to change CARD=1 to CARD=0
if you just have one card.

mkdir ~/.tzap
./scan_uk-t.sh > channels.xml; xml2vdr channels.xml >
~/.tzap/channels.conf

I have not made tzap work, but this seems as good a place to store this
file as any.  If all has gone well you should have a file 


more ~/.tzap/channels.conf

Pick one of your channels and tune in.  Lets go for Channel 4

Channel 4 eng(TV):481833:V:0:27500:2827:2828:2829:0:8384

from this line, the frequency is 481833 the vpid is 2827 and the apid is
2828.  So the command would be 

dvbtune -f 481833


6) Download and install DVB stream from www.linuxstb.org

cd /usr/local/src
wget http://www.linuxstb.org/dvbstream/dvbstream-0.3.tar.gz
cd dvbstream-0.3
make
su -c "cp dumprtp dvbstream rtpfeed ts_filter /usr/local/bin; chmod 755
/usr/local/bin/dumprtp /usr/local/bin/dvbstream /usr/local/bin/rtpfeed
/usr/local/bin/ts_filter"

If you want to watch on a different machine than the one streaming, you
need these binaries on both.  You will also need ts2pes from the DVB cvs


7) Install mplayer

First, if they are not present, you will need to add the gcc3-3.0.1-3
RPMs from your RedHat CD or local mirror, as the default gcc from Redhat
is not supported by the mplayer people.  You may need other packages to
satisfy the dependencies.  For me the following did the trick

rpm -ivh gcc3*.rpm libgcc-3.0.1-3.i386.rpm
libstdc++3-devel-3.0.1-3.i386.rpm libstdc++3-3.0.1-3.i386.rpm
libgcj3-3.0.1-3.i386.rpm  libgcj3-devel-3.0.1-3.i386.rpm
libgcj-2.96-27.i386.rpm

Download the latest mplayer and compile

cd /usr/local/src
wget http://www.mplayerhq.hu/MPlayer/releases/MPlayer-0.60.tar.bz2
bzcat MPlayer-0.60.tar.bz2 | tar xvf -
cd MPlayer-0.60
./configure --cc=gcc3 --enable-gui
ln -s ../DVB/ost/include/ost ost  (the build process does not find these
correctly otherwise)
make
su -c "make install"


8) Start broadcasting some channels across MBone.

We are using Channel 4 for this example vpid of 2827 and a apid of 2828

Add a route to the multicast network then start dvbstream

su -c "/sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0"
dvbstream 2827 2828 &

should result in 

dvbstream v0.3 - (C) Dave Chapman 2001
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Using 224.0.1.2:5004:1
Streaming 2 streams
version=2

You can actually stream as many pids as you like from the same
Multicast, as long as you have the bandwidth.  So you could go for 

dvbstream 2827 2828 512 650 2818 2819 &

which would also stream ITV1 and ITV2 at the same time


9) Start watching.

dumprtp | ts2pes 2827 2828 | Mplayer -cache 2000 -

Make sure you are not running RealPlayer at the same time, it seems to
grab a lock on something stopping Mplayer from working.  I find my audio
is out of sync a little, I am still working on it.


I hope this is of some help.

Scott
