deb-src http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu jaunty main

Install the gpg key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CEC06767

install

aptitude update

aptitude install nvidia-185-modaliases nvidia-glx-185 nvidia-185-libvdpau-dev

mythtv and vdpau is truely amazing

james — Thu, 17 Sep 2009 22:45:24 +0000

Finally have the new nano itx motherboard running. Ubuntu Jaunty with the latest nvidia .run installer. Playing a 720p hd source from our qam source. Right now cpu usage for mythfrontend is only about 19 -20%. system load is right around .44. Amazing that an atom based motherboard could handle playback like this. I am going to try windows 7 media center and xbox media center on it and see how those perform also. So far I am sold. I may invest in another one of these.

Ordered new motherboard

james — Sun, 13 Sep 2009 22:50:45 +0000

I finally ordered the rest of the parts to put together a very small and power efficient pc. I plan to eventually put it in the living room as a mythfrontend. It should work out great once mythtv 0.22 is released. I have been running a test backend for a few months and it seems to be doing just great.

Next part will be a hauppauge hd-pvr.

For now I will be using the M350 for a case. The ZOTAC IONITX-C-U Intel Atom N230 Mini ITX ION for the motherboard. Some memory that I had from another system and the a 8 gig usb thumb drive for the operating system. I will probably just end up pxe booting it from my masterbackend eventually.

How to build .deb packages for mythtv

james — Tue, 04 Aug 2009 20:11:32 +0000

aptitude install autotools-dev fakeroot dh-make build-essential

Instead of running make and make install, just to a checkinstall, you can run a checkinstall –install=no if you do not want to install the package after it is made. So in my case I have a script that makes the packages and I checkout the source and put it in a dir that is the svn version

cd ./$1/mythtv
./configure –prefix=/usr –enable-dvb –dvb-path=/usr/include –enable-xvmc –enable-opengl-vsync –enable-proc-opt –enable-libdts –enable-firewire –enable-xvmc-opengl
qmake mythtv.pro
make -j 2
checkinstall –install=no –pkgversion=0.22 –pkgrelease=$1 –pakdir ../..
cd ../..
pwd
cd ./$1/mythplugins
./configure –prefix=/usr –enable-aac –disable-mytharchive –disable-mythbrowser –disable-mythcontrols –disable-mythgame –disable-mythzoneminder
make -j 2
checkinstall –install=no –pkgversion=0.22 –pkgrelease=$1 –pakdir ../..
cd ../..
pwd
cd ./$1/myththemes
./configure –prefix=/usr
checkinstall –install=no –pkgversion=0.22 –pkgrelease=$1 –pakdir ../..
cd ../..
pwd
cd ./$1/themes
./configure –prefix=/usr
checkinstall –install=no –pkgversion=0.22 –pkgrelease=$1 –pakdir ../..

Requirements to build mythtv .22(trunk) from scratch on jaunty

james — Mon, 27 Jul 2009 20:13:43 +0000

Dependencies:

libfame-0.9 libhtml-template-perl libmjpegtools-1.9 libnet-upnp-perl libphonon4 libpvm3 libqt4-dbus libqt4-designer libqt4-network libqt4-opengl libqt4-qt3support libqt4-script libqt4-sql libqt4-sql-mysql libqt4-webkit libqt4-xml libqtcore4 libqtgui4 libquicktime1 libsox-fmt-alsa libsox-fmt-base libsox1 libxml-namespacesupport-perl libxml-sax-expat-perl libxml-sax-perl libxml-simple-perl mjpegtools mysql-server mysql-server-5.0 mysql-server-core-5.0 ntp phonon phonon-backend-gstreamer pvm pwgen python-mysqldb qt4-qtconfig sox toolame transcode transcode-doc ttf-liberation libqt4-dev nvidia-180-libvdpau nvidia-180-libvdpau-dev

Script I use to make: (command example I use, ./mktrunk.sh 21037)

In the above example 21037 is the svn revision number for trunk, but also the directory name for the source I have checked out for trunk.

cd ./$1/mythtv
./configure –prefix=/usr –enable-dvb –dvb-path=/usr/include –enable-opengl-vsync –enable-proc-opt –enable-firewire –disable-xvmcw –enable-vdpau
qmake-qt4 mythtv.pro
make -j 2

The thing that kept me from compiling from source for a very long time was the qmake line. Make sure you use qmake-qt4 and not the old qmake command. Also make sure you have no qt3 files installed on your building system period.

Slow season for tv shows

james — Thu, 04 Jun 2009 12:29:07 +0000

Since it is the summer season for tv shows and there is very little on, I normally start a refresh of our mythtv system. I am thinking about making the master backend server a vm. I currently have a few vm’s on an esxi4 server. I have a masterbackend up and running and one tuner from our hdhomerun setup on it. Last night was the first recording on the masterbackend. It looked like it handled it just fine. I think I am going to have to rethink this setup. I may just make it an sql server not the masterbackend server.
I have rebuilt on of the frontend with Jaunty. It used to be intrepid. It was a very fast build. From start to finish, probably less than 2 hours. The only problem I had was I forgot to run the backend as the mythtv user so it was causing a system load of about 1.5. After I figured out it was filling up a log file pretty fast it is happy now. The Myth gui seems to be much snappier compared to the intrepid build. I plan to remove the intrepid apt repository I had later today. Next step will be to rebuild the other frontend. It is currently hardy. After that the only other box i have is the current masterbackend and that is hardy also. Not sure if I will rebuilt that as a Jaunty box or not. It will be nice to be all 64bit oses and be able to remove a few sections of the apt repository I keep synced.

Post on mythtvusers to get hdmi audio working

james — Tue, 20 Jan 2009 19:05:45 +0000

—————————————————————————————————
For HDMI cards run aplay -l and look for an output like this:

Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]

For this case, the key is card o device 3.

Setup for Myth:

Audio output device: ALSA:hw:0,3
Passthrough output device: ALSA:hw:0,3
Max Audio Channels: Stereo
Upmix: Passive
Enabale AC3 to SPDIF passthrough checked
Enable DTS to SPDIF passthrough checked
Aggressive sound card buffering off
Use internal volume controls off

For mythmusic:
Utilities/Setup -> Setup -> Media Settings -> Music Settings ->
General Settings
and then set Audio device to ALSA:plughw:0,3

asound.conf may be deleted for myth or changed as below:

asound.conf:

pcm.!default {
type hw
card 0
device 3
}

Getting audio to go over hdmi for mythtv

After using the alsa upgrade script I rebooted and started to work on getting audio going .

Before the upgrade I got the following.
