Hi everyone.
Is there any way to get the supported resolutions?
I’m using OpenGL.
sdl can do that. I clicked “index” in the “docs” folder and then clicked “video”. It said this is a supported function: SDL_ListModes
Hello Team,
We were running this sample example to findout the available modes, on the LCD tv.
#include <SDL/SDL.h>
#include <stdio.h>
int main(int argc, char argv[]) {
/ Information about the current video settings. /
/ Initialize defaults, Video and Audio */
SDL_Rect **fullmodes;
int i;
if((SDL_Init(SDL_INIT_EVERYTHING)) < 0) {
printf(“Could not initialize SDL: %s.\n”, SDL_GetError());
exit(-1);
}
const SDL_VideoInfo *vidInfo = NULL;
vidInfo = SDL_GetVideoInfo ();
/* collect all fullscreen & hardware modes available */
if (!(fullmodes = SDL_ListModes (vidInfo->vfmt,SDL_OPENGL))) {
for(i=0;fullmodes[i];++i)
printf( “SDL Mode: %d: %d x %d\n”, i, fullmodes[i]->w, fullmodes[i]->h);
}
else {
printf(“FullMode Eror\n”);
}
}
The program always fails to list the fullmode.

Any Help on this will be really helpful.
Thanks,
RashmiWell I’m using this for detection on Win32
DISPLAY_DEVICE display;
int displaynum = 0;
memset(&display, 0, sizeof(display));
display.cb = sizeof(display);
// Monitor List
while(EnumDisplayDevices(NULL, displaynum++, &display, NULL))
{
// Default monitor
if (display.StateFlags & DISPLAY_DEVICE_ATTACHED_TO_DESKTOP)
{
DEVMODE devmode;
memset(&devmode, 0, sizeof(devmode));
devmode.dmSize = sizeof(devmode);
int num = 0;
while (EnumDisplaySettings(display.DeviceName, num++, &devmode))
{
// We only want stuff bigger than 640x480 probably
if (devmode.dmBitsPerPel >=16 && devmode.dmPelsWidth >= 640 && devmode.dmPelsHeight >= 480)
{
/* Important stuff
devmode.dmPelsWidth
devmode.dmPelsHeight
devmode.dmDisplayFrequency
devmode.dmBitsPerPel
*/
// Push to list
}
}
}
}
Hope it helps
SDL_LISTMODES is being used by Mplayer and Mplayer crashes, when it tries to access the fullmodes.
Even if we add a NULL pointer check the functionality does not work , when i tried the example program i get to see that
SDL_ListModes is not working as per documentation, so it is very important for me to get the example program working so that Mplayer also runs fine.
SO any help on successfully using this function is very much appreciated.
SDL_Rect **fullmodes;
if (!(fullmodes = SDL_ListModes (vidInfo->vfmt,SDL_SWSURFCE|SDL_FULLSCREEN))) {
for(i=0;fullmodes[i];++i)
printf( “SDL Mode: %d: %d x %d\n”, i, fullmodes[i]->w, fullmodes[i]->h);
}
