Re: [pygame] [BUG] pygame 1.8.1 beta 2 movie module plays MPEG file's sound, but not video

["René Dudfield" <renesd@xxxxxxxxx>]

ah, indeed.

after some more research... The *very* common intel video cards are
one of the baddies of the SDL directx driver... with certain intel
driver versions.

so... I think something like this should be the logic...

if os_version > XP:
    if not os.environ.has_key('SDLVIDEODRIVER'):
        os.environ['SDL_VIDEODRIVER'] = 'windib'
elif directx_version >  8 and video_card == intel_card:
    if not os.environ.has_key('SDLVIDEODRIVER'):
        os.environ['SDL_VIDEODRIVER'] = 'windib'
else:
    if not os.environ.has_key('SDLVIDEODRIVER'):
        os.environ['SDL_VIDEODRIVER'] = 'directx'
