[visonpon]

i test the dlib face detection in my own video(about 10s), but it output only one image ,not output the each frame's face image.

Adjust min_face_scale to proper ratio. Be careful of the output size that if the cropped faces are much smaller than 64x64, it can be detrimental to your model.

Does this program have any requirements for feeding videos? I put a video for about two minutes in the home directory, and then run the dlib_video_face_detection program. After running to the Crop faces section, reported RuntimeError: Expected writable numpy.ndarray with shape set.
