[SDL] VideoInfo->video_mem = 0 ?

[Göttling Thomas]

Hello!

I use SDL & OpenGL.
When I do (After Init & before set video mode):

SDL_VideoInfo * VideoInfo = (struct SDL_VideoInfo *) SDL_GetVideoInfo();

VideoInfo->video_mem indicates 0 Video Ram. Exact as Described here:

But: How can I Get the Amount of available Texture memory then? Isn't there
a possibility? 

Best Regards
Thomas
