[mythtv-users] mythtv on the ps3

ok, I will try and do an installation walk thru. This is all coming from memory, so hopefully I wont forget anything. Im using plain YDL 5.0 and I installed plain 0.20 from mythtv.org (the website source tarballs).

Installing YDL:
Terrasoft has made the process extremely painless. Go here:
http://www.terrasoftsolutions.com/support/installation/
Download the 5.0 pdf. You need to download 2 image files, throw them on some removable media. You also need the YDL 5.0 image, which is located here:
http://ydl.osuosl.org (save this mirror for use with yum)
The above PDF should walk you thru the entire setup.

Post YDL installation setup:
-fix yum. The above image has yum disabled. Edit the /etc/yum.repos.d/*.repo files. Uncomment out the baseurl line. I went ahead and put in the above mirror as my yum repo.
-once you have yum up and running, install the following packages. I just went ahead and installed a bunch of them:
qt-devel qt-MySQL libXv-devel libXvMC-devel libXxf86vm-devel libXmu-devel 
-the above qt package doesnt have the qt source, which is needed to compile myth. I think the qt installed above is qt-x11-free-3.3.6. What I did was install qt 3.3.6 source on my ps3. I configured it and compiled it, then i made sym links from the yum installed package back to the soruce. Specifically, i linked the src and the tools directory. An alternate method would be to just make and install qt from source, rather than do a hybrid yum/source setup as I did.
-setup your video output. Use this as a reference:
http://www.terrasoftsolutions.com/support/solutions/ydl_5.0/video-config.shtml
Basically, go into your kboot and make sure the correct video mode is selected. Seems like this is the only way to configure your video, anything set in xorg.conf gets ignored. Also, its not mentioned on the page, but by adding 128 to the id, it does the video in full mode, which is nice if you dont like having the black border bars. For example, I run 720p, which is mode 3, but I run it in full mode, so i use mode 131. There is a bit of overscan, but this can be corrected in the frontend by positioning it inside your tv.
-make the following changes to your xorg.conf:
Load glx in the module section
Comment out DRI and DPMS lines
I added a DisplaySize to my monitor section (http://www.mythtv.org/wiki/index.php/Display_Size). Unfortunately, this doesnt seem to address the aspect issues I get during playback
-this is optional, but I went ahead and compiled x11vnc and setup my ssh dsa keys and trusted hosts. This allows me to scp and ssh freely between my boxes and to interact with the ps3 over vnc.

Compiling myth:
http://www.mythtv.org/docs/mythtv-HOWTO-4.html
-Go ahead and do steps 4.2, 4.3, 5.1, and 5.4. Thats it, your done!
-To configure, I ran the following:
./configure --enable-proc-opt
-I went ahead and used plain 0.20 because thats what im running as my backend. I compiled and tested the .20fixes off the svn and that worked as well.

mythfrontend setup:
To get audio to work, change the audio device from /dev/dsp to ALSA:default and change the mixer to default.

I think thats it, im pretty sure I missed a step, so just let me know if you get stuck. As I stated above, right now im running into performance issues. Video playback is the main one, but some themes can also bog you down. Maybe someone can recommend some good video tweaks to address this. YDL uses a plain frame buffer to output video, no GPU. This means everything is done on the cell cpu. I think its very possible to have the cell push out video, this is what it was made for. It runs at 3.2ghz and has 6 available cores on YDL. Someone just needs to figure out how to do it :) Either that or get some basic video support from the nvidia gpu.
