I am working on a demo that demonstrates the usage of NvBufSurfTransform, here is the core code:

void Test() {
  uint32_t width = 1920;
  uint32_t height = 1080;

  uint32_t dst_width = 640;
  uint32_t dst_height = 360;
  NvBufSurfaceCreateParams params1 = {
      .gpuId = 0,
      .width = width,
      .height = height,
      .size = 0,
      .isContiguous = true,
      .colorFormat = NVBUF_COLOR_FORMAT_RGBA,
      .layout = NVBUF_LAYOUT_PITCH,
      .memType = NVBUF_MEM_SURFACE_ARRAY,
  };
  NvBufSurface *surface1 = NULL;
  int ret = NvBufSurfaceCreate(&surface1, 1, &params1);
  if(ret != 0 || !surface1) {
    exit(-1);
  }

  ret = NvBufSurfaceMemSet (surface1, -1, -1, 255);
  if(ret != 0) {
    exit(-1);
  }

  NvBufSurfaceCreateParams params2 = {
      .gpuId = 0,
      .width = dst_width,
      .height = dst_height,
      .size = 0,
      .isContiguous = true,
      .colorFormat = NVBUF_COLOR_FORMAT_RGBA,
      .layout = NVBUF_LAYOUT_PITCH,
      .memType = NVBUF_MEM_SURFACE_ARRAY,
  };
  NvBufSurface *surface2 = NULL;
  ret = NvBufSurfaceCreate(&surface2, 1, &params2);
  if(ret != 0 || !surface2) {
    exit(-1);
  }

  NvBufSurfTransformRect src_rect, dst_rect;

  src_rect.top   = 0;
  src_rect.left  = 0;
  src_rect.width = width;
  src_rect.height = height;

  dst_rect.top   = 0;
  dst_rect.left  = 0;
  dst_rect.width = dst_width;
  dst_rect.height = dst_height;

  NvBufSurfTransformParams nvbufsurface_params;
  memset(&nvbufsurface_params, 0, sizeof(nvbufsurface_params));
	nvbufsurface_params.src_rect = &src_rect;
	nvbufsurface_params.dst_rect = &dst_rect;
	nvbufsurface_params.transform_filter = NvBufSurfTransformInter_Default;
	nvbufsurface_params.transform_flag =  NVBUFSURF_TRANSFORM_CROP_SRC | NVBUFSURF_TRANSFORM_CROP_DST | NVBUFSURF_TRANSFORM_FILTER;

  NvBufSurfTransformConfigParams transform_config_params;
  memset(&transform_config_params, 0, sizeof(transform_config_params));
	transform_config_params.compute_mode = NvBufSurfTransformCompute_Default;
	ret = NvBufSurfTransformSetSessionParams (&transform_config_params);
  if(ret != 0) {
    exit(-1);
  }

  ret = NvBufSurfaceMemSet (surface2, -1, -1, 0);
  if(ret != 0) {
    exit(-1);
  }
  ret = NvBufSurfTransform (surface1, surface2, &nvbufsurface_params);
  
  if (ret != NvBufSurfTransformError_Success) {
     printf ("NvBufSurfTransform failed with error %d while converting buffer\n", ret);
  }
 
}

When I running the demo, the NvBufSurfTransform will return -3, that is NvBufSurfTransformError_Invalid_Params. Then I further set DBG_NVBUFSURFTRANSFORM in my env, the logs is here:
