尽管pNVIFR为null，但NvIFR_CreateEx成功

嗨，
我正在尝试使用H264编码。
我的代码非常小，看起来像这样
.....
hr = D3D11CreateDevice（NULL，D3D_DRIVER_TYPE_HARDWARE，NULL，0，NULL，0，D3D11_SDK_VERSION，＆amp; pDevice，＆amp; featureLevel，＆amp; pDeviceContext）;
.....
NVIFR_CREATE_PARAMS参数= {0};
params.dwVersion = NVIFR_CREATE_PARAMS_VER;
params.dwInterfaceType = NVIFR_TOH264HWENCODER;
params.pDevice = pDevice;
NvIFR_CreateEx_fn（安培; PARAMS）;
.....
NvIFR_CreateEx_fn成功并返回NVIFR_SUCCESS。
但是params.pNvIFR为null。
有没有人有关于如何正确工作的想法？
谢谢。

Hi,

I am experimenting with H264 encoding. My code is very minimal and appears something like this

.....
hr = D3D11CreateDevice(NULL, D3D_DRIVER_TYPE_HARDWARE, NULL, 0, NULL, 0, D3D11_SDK_VERSION, &pDevice, &featureLevel, &pDeviceContext);
.....
NVIFR_CREATE_PARAMS params = { 0 };
params.dwVersion = NVIFR_CREATE_PARAMS_VER;
params.dwInterfaceType = NVIFR_TOH264HWENCODER;
params.pDevice = pDevice;

NvIFR_CreateEx_fn(¶ms);
.....


NvIFR_CreateEx_fn succeeds and returns NVIFR_SUCCESS.
However params.pNvIFR is null.

Does anyone have ideas on how to get this work correctly?

Thanks.
