SDL_Texture *YUVtexture = SDL_CreateTexture(render, SDL_PIXELFORMAT_IYUV, /* YV12/NV12... */, SDL_TEXTUREACCESS_TARGET, width, height);
if (texture)

SDL_UpdateYUVTexture(YUVtexture, NULL, yPlane, yPicth, uPlane, uPicth, vPlane, vPicth);

SDL_Texture *RGBtexture = SDL_CreateTexture(render, SDL_PIXELFORMAT_ARGB8888, SDL_TEXTUREACCESS_STATIC, width, height);
SDL_UpdateTexture(RGBtexture, NULL, rgbData, rgbPitch);

SDL_SetRenderTarget(m_render, YUVtexture);
SDL_RenderCopy(m_render, RGBtexture, NULL, NULL); /* Copy RGB texture to YUV texture */
SDL_SetRenderTarget(m_render, NULL);

SDL_RenderCopy(m_render, YUVtexture, NULL, NULL); /* RGB texture without color */
