[BUG?] in SDL_GetVideoInfo

SDL Development
1

Hi,

I’m using SDL CVS on linux.
Consider this code snippet (SDL is initialized)

const SDL_VideoInfo* info = SDL_GetVideoInfo();
printf(" > Video memory: %uK\n", info->video_mem);

When executing this I get:

Video memory: 0K

What am I doing wrong? Or is this a known issue / bug?

Thanks in advance,
Florian Schanda

Video memory is only relevant with a hardware surface, which you never get
under X11.

Oh! Ok.

I was thinking that this gives me my total memory. See, I was hoping to figure
out the amount of texture memort, since I’m writin an OpenGL app. Is there
any easy cross-plattform way to figure this out?
(I know I can just load textures ad nauseum and check if they’re resident, but
that a mess…)

Thanks,

Under X11 perhaps, but under DGA?On Sun, May 19, 2002 at 12:47:14PM -0400, Ryan C. Gordon wrote:

This information almost useless anyway because it doesn’t tell you how much
hardware surfaces you can get. It always depends on your resolution, hardware
etc. so testing is the better way.

You’ve got a point. And that makes the information not very useful
overall. Perhaps it should be considered for the SDL 1.3 chopping block?On Mon, May 20, 2002 at 01:58:42PM +0200, Stephan Goetter wrote:

What’s this message on my screen,
so blue, so blue, what could it mean?
Could you, would you press Delete,
Ctrl and Alt and then repeat.
