[linuxtv-softmpeg] libsoftmeg on Matrox G550 problem

[T.Scholz@Brunel.de]

Hello all,

I'm having troubles getting libsoftmpeg to run. The problem is that the
screen only turns black.

This is my configuration:

Matrox G550 graphics card:
pci bus 0x0001 cardnum 0x00 function 0x00: vendor 0x102b device 0x2527
 Matrox Graphics, Inc. MGA G550 AGP

Kernel: 2.6.7-gentoo-r11

DirectFB: cvs 2004-08-01

libsoftmpeg: cvs 2004-08-01

VDR: 1.3.11


Everything seems to compile well. Now, when I run

# ./vdr -P"softmpeg"

I get the following output:

When I comment out the first line in directfbrc:

I get the follwing errors:

Does anyone have a hint what's wrong ?
Is directfbrc and fb.modes correct ?
Do I need some configure options for the compilation of DirectFB ?
Is there a problem with my kernel ?
Which components do I have to compile in ?  Do I need some kernel options ?
Do I need some patches ?

Any help is appreciated.

Thanks, Th.
