on mgras (Impact) based SGIs it currently bombs out while testing the usable
texture size:

SwScaler: using unscaled Planar YV12 -> BGR 24-bit special converter
VO: [gl2] 480x208 => 480x208 BGR 24-bit  [zoom]
[gl2] OpenGL Driver Information:
        vendor: SGI,
        renderer IMPACT/2/2/4,
        version 1.1 Irix 6.5
[gl2] You have OpenGL < 1.2 drivers, BAD (16bpp and BGR may be damaged!)
[gl2] Needed texture [256x512] too big, trying [256x256] !
[gl2] Needed texture [256x256] too big, trying [128x256] !
[gl2] Needed texture [128x256] too big, trying [128x128] !
[gl2] Needed texture [128x128] too big, trying [64x128] !
[gl2] Needed texture [64x128] too big, trying [64x64] !
[gl2] Needed texture [64x64] too big, trying [32x64] !
GLERROR: Give up .. usable texture size not avaiable, or texture config error !
FATAL: Cannot initialize video driver.

I added some fprintf to that section to find out with what values the
texture gets initialized. gl_bitmap_format_s is set to GL_BGR while 
gl_internal_format_s is set to GL_RGB, which apparently doesn't work out.
If I hardcode gl_bitmap_format to GL_RGB too it works but with corrupted colors.
Using that version with -vop rgb2bgr produced correct colors (and a major
slowdown).
I now realized that the unmodified version also works with -vop rgb2bgr, hmmm.. 
Unfortunately i don't know shit about opengl coding so I'm basically digging in
the dark here..

so long,
Timo
