[vlc] vlc on PXA-framebuffer - initialization problem

[Holger Kummert]

Hello,

I have problems to run vlc 0.6.0 on an embedded arm-based system without
any X/GTK/wxWindows support. The processor is an Intel XScale PXA250. The
only graphical output-device is the framebuffer.  It seems that vlc isn't
able to initialize the framebuffer.
I thing that the main error message is

    fb video output error: cannot get terminal mode (Invalid argument)

When I look in the kernel code (version is 2.4.19, with patches to run on
PXA250), I can see that vlc tries to get tty-information from device '0'
(hardcoded in fb.c, function Create()). Is this related to /dev/fb0?

When I start vlc from a serial connection (ttyS0) or from tty0, the
framebuffer (resolution is 400x234) remains unchanged.  But framebuffer is
actually working, e.g.  "cat bootsplash > /dev/fb0" shows a picture on the
screen, Qt (OPIE) is also running.

The output when I start vlc is:

# vlc -vvv nbsaintro.mpg --fbdev /dev/fb0 --fullscreen
