SDL difficulties

herg · 2007-08-14, 23:32

Hey, guys. I'm attempting to get XBMC running on my Feisty box, and I'm running into some difficulties. It compiles fine, but running it is another story.

I'm fairly familiar with Linux in general including a couple of years of experience on embedded platforms in my job. Ubuntu and SDL on the other hand...

First problem, SDL is trying to use the framebuffer. Well, I don't have a fb device available, but it shouldn't be writing directly to the framebuffer anyway, should it?

Code:

herg@leela:~/projects/XBMC$ ./XboxMediaCenter

(!) DirectFB/Core: Could not initialize 'system' core!
    --> Initialization error!

Running the application...
Segmentation fault (core dumped)

So, I tell it to use x11 instead.

Code:

herg@leela:~/projects/XBMC$ export SDL_VIDEODRIVER=x11
herg@leela:~/projects/XBMC$ ./XboxMediaCenter

Hmmm... I've used envy to configure the latest driver for my card (GeForce 6600 LE). Maybe it's running at the wrong bitdepth.

Code:

herg@leela:~/projects/XBMC$ cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder3)  Wed Jun 13 18:39:30 PDT 2007

Just a quick update. I built XBMC with --disable-gl, and while it still doesn't work with my video card, I can direct it to a VNC display. I do not see text, but I do get the home screen with images and such.

Pretty much confirms that it is a video card configuration problem.

What version of the nvidia drivers are you using?
Post the output of glxinfo.

herg · 2007-08-15, 01:51

Thanks for the response, but I dragged the box into the living room and hooked it up to the Plasma, and it is working fine now. I guess the crappy LCD I have in the office was not playing well.

I still have no text, but that seems like a much more manageable problem.

untg99 · 2007-08-15, 02:17

If that's the text you see on the screen when the GUI appears, I have the same problem, look for an error about fonts in the terminal screen and you should be able to find the problem.

I've had this problem with three separate installs.
Probably because I'm using these instructions
http://www.xboxmediacenter.com/wiki/...om_source_code
and not using build.sh or the T3... script....not sure but copying the font over does work for me.

**althekiller** · 2007-08-15, 12:10

Use the damned build script!

herg · 2007-08-15, 14:56

I did. The problem was that I wasn't running out of the BUILD directory.

I only had a few minutes before I went to a friend's house, but I did try a quick video. A 720p x264 mkv at 70% CPU on a 2.6 GHz Celeron. Very nice.

I've wanted to build a HTPC for a while now, but couldn't find any software I liked nearly as well as XBMC. I guess it's time to buy a cheap sound card with digital out and figure out where I can help.

**spiff** · 2007-08-15, 14:58

you can start by getting digital out going

I'm trying to get xbmc-linux to work in VMware Fusion (on my power book).

VMware Fusion does not support openGL rendering (only DirectX 8.2) so running xbmc with enabled 3d support is extreamly slow..

When I compile xbmc without 3d support the fonts are not rendered at the correct positions, this is my log from xbmc without 3d support http://pastebin.com/m4e3fe86c . Have I made something wrong or is the 2d version broken?

(Running latest svn version 9952)

probably best if you start a new topic-thread for that issue
