我正在尝试构建一个使用人脸识别库实时检测人脸的软件。我使用网络摄像头进行了尝试，结果令人满意且帧速率相当稳定，但是当我切换到 .mp4 视频时，结果在 fps 方面非常糟糕。我在 OpenCV 中使用 Python 3.6，这是我正在使用的代码：

import face_recognition
import cv2


# Load a sample picture and learn how to recognize it.
totti_image = face_recognition.load_image_file("totti.jpg")
totti_face_encoding = face_recognition.face_encodings(totti_image)[0]

# Create arrays of known face encodings and their names
known_face_encodings = [
    totti_face_encoding
]
known_face_names = [
    "Francesco Totti"
]
def get_faces(frame):
    # Convert the image from BGR color (which OpenCV uses) to RGB color (which face_recognition uses)
    rgb_frame = frame[:, :, ::-1]

    # Find all the faces and …
