[Opalvoip-devel] Problems implement SDL2.0 PVideoOutputDevice

[John C. <zho...@gm...>]

Hi,
I'm trying to implement  SDL2.0  PVideoOutputDevice.I need to call
SDL_UpdateYUVTexture in  PVideoOutputDevice::SetFrameData.
How can i get the (YUV)plane and (YUV)pitch from data?

Code:

PBoolean PVideoOutputDevice_SDL2::SetFrameData(unsigned x, unsigned y,
                                          unsigned width, unsigned height,
                                          const BYTE * data,
                                          PBoolean endFrame) {

   //TODO plane?pitch?

SDL_UpdateYUVTexture(sdlTexture,sdlTect,Yplane,Ypitch,Uplane,Upitch,Vplane,Vpitch);
   SDL_RenderClear(sdlRenderer);
   SDL_RenderCopy(sdlRenderer, sdlTexture, NULL, NULL);
   SDL_RenderPresent(sdlRenderer);
}


SDL 2.0 API:

int SDL_UpdateYUVTexture(SDL_Texture*    texture,
                         const SDL_Rect* rect,
                         const Uint8*    Yplane,
                         int             Ypitch,
                         const Uint8*    Uplane,
                         int             Upitch,
                         const Uint8*    Vplane,
                         int             Vpitch)



Thanks!
