Problem with SDL 1.3 in Qt Widget

SDL Development
1

Hi everybody,

I’m working on a video player that needs to play more video at the same time.
I get one window by widget, and one renderer by window to display a different color in each of them.
It Works.

The problem arises when I replace the color by a video texture,
I can’t resize my texture to the display zone when i call SDL_RenderCopy(m_sdl_renderer, video_texture, NULL,NULL);

I have a display of my picture but it is much smaller than the display area size.

Could you help me to resolve this problem ?

Thanks a lot

Ps: I use this code to display my texture

video_texture = SDL_CreateTextureFromSurface(m_sdl_renderer,frame_received);
if(video_texture)
{
SDL_RenderClear(m_sdl_renderer);
SDL_RenderCopy(m_sdl_renderer, video_texture, NULL,NULL);
//SDL_SetRenderDrawColor(m_sdl_renderer,255,0,0,0);
SDL_RenderPresent(m_sdl_renderer);
SDL_DestroyTexture(video_texture);
}

Hi, if i remember correctly I had a very similar problem, but only
when using the software renderer on a quite old sdl revision. Are you
up to date and using an accelerated renderer?
If not, could you post more code so that others can verify what’s going on?
Best,
