[Freevo-hardware] DirectFB Matrox G450 with zsnes/fceu tvout

[Shawn D. <sha...@gm...>]

After much trial and error I have been successful getting Freevo
working properly with this hardware.  Freevo and mplayer work
properly, I followed the howtos at

http://www.sci.fi/%7Esyrjala/directfb/matrox-tv-out-howto   and
http://68.44.117.181/matrox.html

Anyhow, everything works great except I can't get any other software
to work properly.  Zsnes and fceu both segfault when run.

Here's my setup:

/etc/directfbrc:
matrox-crtc2
matrox-tv-standard=ntsc
primary-layer=2

It doesn't matter what I do with these environment variables (except I
need the first one for the emulators to use DirectFB), but these are
what I've tried:
export SDL_VIDEODRIVER=directfb
unset SDL_VIDEO_YUV_DIRECT
export SDL_VIDEO_YUV_HWACCEL=1
export SDL_DIRECTFB_MGA_CRTC2=1
export SDL_DIRECTFB_MGA_STRETCH=1
export SDL_DIRECTFB_MGA_OVERSCAN=1

If I don't set any of these variables then I can run both Zsnes and
fceu (I can hear sound but DirectFB is not initialized so all I see is
flickering, but changing flickering)

If I set:
export SDL_VIDEODRIVER=directfb
unset SDL_VIDEO_YUV_DIRECT
export SDL_VIDEO_YUV_HWACCEL=1
export SDL_DIRECTFB_MGA_CRTC2=1

then nothing works except mplayer.  But freevo won't start properly.

I'm using Freevo 1.5.1, SDL 1.2.7, kernel 2.4.26, DirectFB 0.9.20
I followed all of the directions for patching everything.

Here's the output of Zsnes when it doesn't work:
(*) parsing config file '/etc/directfbrc'.

And from fceu:
it works, but displays either a blue or green screen depending on the
depth I run it at (blue for 8 and 32 bit, green for 16 bit)  I know
this may belong more in the directfb boards, but I know many people
here have been successful getting these to work, so I was hoping
someone here might be able to help.  I thank you for any help you may
be able to give me.
