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.

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.

Getting audio to go over hdmi for mythtv

upgrading alsa on ubuntu

james — Tue, 20 Jan 2009 16:05:38 +0000

After a bunch of digging trying to get audio over hdmi on my new motherboard working, I stumbled upon a script that was created for doing exactly what I need to do. If you go to http://ubuntuforums.org/showthread.php?t=962695&page=6 you will find very good info on this subject. What i have done is download the script file. Untared it and then ran it the following way.

 sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -d
 sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -c
 sudo ./AlsaUpgrade-1.0.x-rev-1.16.sh -i

Be patient each step can take some time. After the upgrade reboot and then do an aplay -l to list all of your devices. This is where it gets tricky. Depending on your hardware you may have to do different things in mythtv to get audio going through hdmi.

Updated: The day after I went through this process the script was updated. I have updated the commands above. Looks like this process worked on newer kernels but not older ones. Intrepid it worked fine for me but hardy it did not. The new script and version of alsa works perfect on hardy now.

fstab uuid

james — Wed, 17 Dec 2008 00:00:39 +0000

If you want to mount a drive using uuid just partition the drive and then run
vol_id -u /dev/sda1 (in karmic just do a ls -la /dev/disk/by-uuid)
sda1 is an example, you may have a different drive you are working on.
when you get the uuid you can create the entry in /etc/fstab. You will need to reboot at least once after the drive has been partitioned.
