opencv_test_cudacodec fails

edit

Hello! I'm trying to run test opencv_test_cudacodec but getting errors. First I get CUDA_ERROR_INVALID_SOURCE in cuvid_video_source.cpp:

CUresult cuRes = cuvidCreateVideoSource(&videoSource_, fname.c_str(), &params);
if (cuRes == CUDA_ERROR_INVALID_SOURCE)
  throw std::runtime_error("");

Then we catch exception in video_reader.cpp and try create FFmpegVideoSource:

    catch (...)
   {
    Ptr<RawVideoSource> source(new FFmpegVideoSource(filename));
    videoSource.reset(new RawVideoSourceWrapper(source));
   }

But in the ffmpeg_video_source.cpp I get null in stream_:

 stream_ = create_InputMediaStream_FFMPEG_p(fname.c_str(), &codec, &chroma_format, &width, &height);
if (!stream_)
  CV_Error(Error::StsUnsupportedFormat, "Unsupported video source");

In console I see text:

Available options besides google test option:
 Usage: opencv_test_cudacodecd.exe [params]
