dViCO MythTV CentOS Use Case
My wife and I have been using the DViCO FusionHDTV DVB-T Dual Express with mythtv on CentOS x86_64 as our PVR and TV since Feb2008. MythTv is configured to program the motherboard Real Time Clock interrupt to powerup the pc from an off state to record programs, and poweroff the pc once a recording is complete. The motherboard is an Asus p5K, Core2 Q6600 2.40GHz, ATI Radeon 1950 pro, Silverstone LC20B, SeaSonic 650W PSU. The setup is dual head using 2 22inch wide screen lcds, great for running the TV on one screen while reading email etc on the other. A small usb keyboard with a long cable has been a successful replacement for IR remote control. The screens are only 1.5m from our lounge chair. At 1.5m a larger screen would be perfect for reading small text in a browser at 1680x1050. Would like to investigate xorg multiseat as addition to this setup.
Tasks: -Finish the key mapping for the IR controller. -Develop a fix for the EIT. EIT uses the networkid in table dtv_multiplex and populating this breaks reception ABCHDTV. XMLTV works fine. On several occasions the programming from xmltv was incorrect so I have disabled it and used the tv guide from the paper since! -Investigate a live TV display problem when switching from an SD to HD channel. From SD to SD and HD to HD ok. The work around is to exit the display and re-enter. Some sort of initialisation problem and is probably poor configuration on my part. (Utilities/Setup -> Setup -> TV Settings -> Playback -> Playback Profiles (3/9)). -Investigate a LiveTV freeze problem. Only occasional on our worst 2 channels for reception. Due to errors in the transport stream due to interference. If watching prerecorded the freeze does not occur (only screen jumps etc). Work around is to exit live tv and re enter.
Well worth the effort to configure!
- Centos 5.1 installation - linux-2.6.23 kernel source - Attansic_L.rar lan driver from asus. - ati-driver-installer-8.443.1-x86.x86_64.run - linuxtv-dvb-apps-1.1.1 - xc-test-d4f7804a393c Chris Pascoe v4l source
Now trying to find a spot for example config files scripts etc.

Install everything short of xen, clustering etc.
When installing a second redhat installation remember to rename the volume group so it does not clash with the original installation so you can mount both volume groups at the same time. Also check the partitions mounted by the label name are the right ones eg boot sda1 my be mounted instead of sdb1 because both labels=boot. Just remove the label in fstab and use the device instead of the label.
Build eth driver(onboard P5K lan adapter) and configure eth0.

rejig the kernel dependancies:
sudo depmod -a
Look in /lib/modules/<kernelver>/kernel/modules.dep for the dependancies of a module, or run:
sudo modprobe --show-depends <modulename>
insert the new modules into the kernel:
sudo modprobe -a cx23885 tuner-xc2028 zl10353
lsmod should show the modules loaded. The new devices are: tree /dev/dvb /dev/dvb
|-- adapter0 | |-- demux0 | |-- dvr0 | |-- frontend0 | `-- net0 `-- adapter1 |-- demux0 |-- dvr0 |-- frontend0 `-- net0
To test the operation of the devices load install linuxtv-dvb-apps-1.1.1
cd /u01/install/linuxtv-dvb-apps-1.1.1/util/scan/ ./scan ./dvb-t/au-goldcoast
The output is used to build a channels.conf eg for channel SC10HD
To tune into the channel run
./tzap -r -c channels.conf SC10HD
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 634625000 Hz video pid 0x09cf, audio pid 0x09d0 status 00 | signal 2888 | snr 0000 | ber 00000000 | unc 00000000 | status 1e | signal b314 | snr cdcd | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1e | signal b310 | snr cccc | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1e | signal b364 | snr cccc | ber 00000000 | unc 00000000 | FE_HAS_LOCK
Channel SC10HD is now locked and the mpeg transport stream is available on /dev/dvb/adapter0/dvr0 and can be played with mplayer. channels.conf may require tweaking so the correct the correct pid is demultiplexed from the transport stream.
For installation of mplayer and mythtv.
Configure yum - rpm package installer
Check yum installer has disabled the removal of rpms in /var/cache/yum after the install. (you may need in future)
sudo vi /etc/yum.conf
These directions are from the centos website:
Configure yum with priorities so core CentOS libraries are not overwritten:
yum install yum-priorities
Make sure that yum-priorities is enabled by editing the /etc/yum/pluginconf.d/priorities.conf file, and ensuring that it contains the following lines:
Edit the .repo files in /etc/yum.repos.d/ and set up priorities by adding the line:
to a repository entry, where N is an integer number from 1 to 99.
The recommended settings are:
[base], [addons], [updates], [extras] ... priority=1 [centosplus],[contrib] ... priority=2
Third Party Repos such as rpmforge ... priority=N (where N is > 10 and based on your preference)
Install DAG's GPG key:
Verify the package you have downloaded
rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
Security warning: The rpmforge-release package imports GPG keys into your RPM database. As long as you have verified the package and trust Dag then it should be safe.
Install the package
rpm -i rpmforge-release-0.3.6-1.el5.rf.*.rpm
This will add a yum repository config file and import the appropriate GPG keys. At this point, you can set the priority of the RPMForge repository, and also of the CentOS repositories if you have not done so yet.
Set the priority=10 for [rpmforge] in /etc/yum.repos.d/rpmforge.repo
Test with this command:
It should output these two lines:
Loading "priorities" plugin ... 76 packages excluded due to repository priority protections
The number above may differ, but there should be several packages shown as being excluded.
If so then it looks like things are working so try installing something like this
yum install mplayer
Install mplayer and test.
yum install mplayer
Add to /etc/yum.conf - Axel Thimms is the only mythtv packager.
[atrpms] enabled=1 priority=10 name=CentOS el$releasever - $basearch - ATrpms baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable http://www.mirrorservice.org/sites/download.atrpms.net/el$releasever-$basearch/atrpms/stable http://wftp.tu-chemnitz.de/pub/linux/ATrpms/el$releasever-$basearch/atrpms/stable http://mirrors.ircam.fr/pub/atrpms/el$releasever-$basearch/atrpms/stable gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms gpgcheck=1
You can also include the test repo as suggested by:
This will avoid the missing dependancies in the next step.
yum install mythtv
Could not resolve these:

The mythtv channel scanner did not do a good job on some channels so I manually configured all my channels in channels.conf, tested with tzap and mplayer until correct. I then created channel2myth0.21 to convert channel.conf to a sql update script for upload into the mythconverg mysql database.
Create a sql insert script for mythtv channels:
./channel2myth0.21.sh > channel.sql
Run mysql, backup the original channel data, and do the update.
mysql -u root -p use mythconverg select * from channel into outfile '/tmp/channel.data'; select * from dtv_multiplex into outfile '/tmp/dtv_multiplex.data'; delete from channels; delete from dtv_multiplex; source ./channel.sql commit;
The only data missing is dtv_multiplex.networkid for operation of EIT and can be found by running dvbsnoop. Entering a networkid for ABCHDTV seems to break the tuner locking mechanism for this channel. If this happens follow the note below for channel tuning failure.
May need to update the default startup channel under because we just clobbered the original channels:
mythtv-setup -> Input Connections DVB0 and DVB1 -> Starting Channel.
Run mythfrontend. I set the option: -geometry 1680x1049
Utilities/Setup -> Setup -> Appearance -> Screen settings Gui width (px): 1680 Gui height(px); 1049
Utilities/Setup -> Setup -> TV Settings -> Playback -> Playback Profiles (3/9))
Create a new profile: Match Criteria: > W: 1 H: 1 Match Criteria: > W: 1 H: 1 Decoder: Standard MaxCPUs: 4 VideoRenderer: xv-blit OSDRenderer: chromakey OSDFade off (This probably needs adjusting to fix a problem when changing from a HD channel to an SD channel and vis-versa.)
Channel Tuning Failure
If something goes wrong with channel tuning -> Delete all cards,video sources, etc in mythtv-setup and start again. (There is a bug with deleting selections - need to delete all.)
Automatic Program Recording Machine Power Up/Down
Setup start scripts for mysqld and mythbackend: The scripts should be installed in /etc/rc.d/init.d on installation.
chkconfig --list mysqld chkconfig --list mythbackend
If not set to start, set startup for runlevel 5
sudo chkconfig --level 5 mythbackend on sudo chkconfig --level 5 mysqld on
Copy mythCheck.sh, mythSetTime.sh, mythDoShut.sh matching the configuration of mythtv-setup for these scripts.
cp mythCheck.sh mythSetTime.sh mythDoShut.sh /u01/vault/mythtv
sudo mv /usr/bin/mythfrontend /usr/bin/mythfrontend.bin
Copy the mythfrontend bash script into place.
sudo cp mythfrontend /usr/bin/mythfrontend.
Setup sudoers for mythbackend see notes in /usr/bin/mythfrontend script.
Setup mythfrontend with icon under kde with the command:
kstart --ontop mythfrontend
(doesn't seem run fullscreen under gnome, unless you set it manually from the task bar.)
1) At machine startup mythbackend starts and will terminate if it is not required eg.no program recording. 2) If no program is recording the script mythCheck.sh is called to check for active mythfrontend sessions. 3) When mythbackend terminates (no frontend running, no recording): a) first mythSetTime.sh is called and sets: - the realtime clock interrupt to start the machine at the time of the next recording from a powered off state. - an 'at' job to startup mythbackend for when the machine is on and mythbackend has terminated. b) second mythDoShut.sh is called to shutdown the machine. The backend will not shutdown if a process called 'gnome-session' is found or the machine has been up for less than 5min.
To test that everything is working, plug in the USB receiver and do a 'dmesg |grep hiddev' to make sure it's been picked up fine. Run lircd and check that the remote is being picked up:
# /usr/local/sbin/lircd --device=/dev/hiddev0 # irw
Point your remote at the receiver, press some buttons and you should see some action on the screen. Once you're happy your remote works, press CTRL-C to exit irw. Add the following lines to /etc/rc.d/rc.local to have lircd start up automaticall every boot.
echo "Starting lircd" /usr/local/sbin/lircd --driver=dvico --device=/dev/hiddev0
Grab this lircrc.example file and save it as /home/mythtv/.lircrc
$ wget http://www.users.on.net/~jani/lircrc.example.DVICO-irxevent $ mv lircrc.example.DVICO-irxevent ~/.lircrc
And to get irxevent to automatically start when user 'mythtv' logs in, run the following command as mythtv.
$ ln -s /usr/local/bin/irxevent ~/.kde/Autostart/irxevent
