Mythtv

1 install mythtv

install mythtv

Note that I do not use the following sources:

deb http://dijkstra.csh.rit.edu:8088/~mdz/debian woody mythtv
deb-src http://dijkstra.csh.rit.edu:8088/~mdz/debian woody mythtv

because it is not meant for the epia M 9000 (compiled for pentiumpro architecture) and I want to have a single installation for my M1000 and M9000 boxes.

Important note

In order to have mythtv working with the VIA CLE266 MPEG decoding engine you _*need*_ to run both mythbackend and mythtv as _*root*_ otherwise all you will get a black screen and a big fat segfault. Gryle revealed me that it comes from the fact that libddmpeg has some hardware I/O instructions (inb or outb) and only root or the kernel is allowed to do that. The solution would be to integrate that part of the code in the kernel (via_v4l_drv module) or in the X server...

for all users add in their path:

export PATH=${PATH}:/usr/share/qt3
export QTDIR=/usr/lib/qt3

build the core and plugins. In order to avoid conflict with a classical debian package and also in order to enable an easy removal, mythtv is installed in directory /opt/mythtv-cvs

Edit the /var/www/html/mythweb/config/conf.php file if required. By default, MythWeb uses an Apache .htaccess file to restrict access to the website and to configure some variables. To create the password file for Apache (if your system doesn't already have one), you could do something like this:

run mythtv-setup and define general setup capture card source and link capture card tuner to source and use the following external script to change channels: /usr/local/bin/ptune.pl
create a .xawtv file containing the exact frequencies of your channels:

defaults
color = 32768
bright = 36000
hue =  32768
contrast = 32000
norm = SECAM
source = Television
freqtab = france

#
# Channel options
#
TF1
channel = 50

France2
channel = 52

France3
channel = 55

Canal+
channel = 63
fine = 4
capture = grab

Arte
channel = 47
fine = 1

M6
channel = 68

Planete
channel = 23
fine = 2

Serie club
channel = 26
fine = 2

LCI
channel = 31

Info sports
channel = 60

Paris premiere
channel = 66

identify source id of your cardinput using

mysql -uroot -prootmysqlpasswd
use mythconverg
select * from cardinput\G
*************************** 1. row ***************************
    cardinputid: 8
         cardid: 10

     preference: NULL
      shareable: N
       tunechan: 50
      startchan: 50
1 row in set (0.01 sec)

here sourceid is 13

and then populate database (substitute 13 by your sourceid):

mythfilldatabase --xawchannels 13 .xawtv

verify acquisition

mysql -uroot -prootmysqlpasswd
use mythconverg

use tv_grab_fr to retreive the my tv guide from the net (http://membled.com/work/apps/xmltv/new_grabbers/tv_grab_fr)

tv_grab_fr > allprogs.xml

tv_grab_fr uses a horrid Windows font that replaces a-grave with an r-acute. Change the font:

cat allprogs.xml | sed 's/Windows-1250/ISO-8859-1/g'  > myprogs.xml

If have one station for France 5 / Arte should do this instead

cat allprogs.xml | sed 's/\"Arte\"/\"France5\/Arte:\"/g' | sed 's/\"France5\"/\"France5\/Arte:\"/g' | sed 's/Windows-1250/ISO-8859-1/g'  > myprogs.xml

Now fill the program guide (13 is my sourceid)

mythfilldatabase --file 13 -1 myprogs.xml

This version leaves channel data in place

mythfilldatabase --update --file 13 -1 prog.xml
rm allprogs.xml myprogs.xml

tv_grab_fr > allprogs.xml
cat allprogs.xml | sed 's/Windows-1250/ISO-8859-1/g'  > myprogs.xml
cat myprogs.xml | sed 's/France5/Arte/g' > finalprogs.xml
mythfilldatabase --file 13 -1 finalprogs.xml

Compilation on both ezra and nehemiah architectures

disp()

}

warn()
{
  echo "WARNING: $@" >&2
}

die()
{
  echo "FAILURE: $@" >&2
  exit 1
}

 $# -ne 1  && die "Usage : $0 <arch>
where <arch> stands for ezra or nehemiah"

arch=$1
