To fix compile
error C2146: syntax error: missing ';' before identifier 'PVOID64',
change typedef void * POINTER_64 PVOID64;
to typedef void * __ptr64 PVOID64;
in winnt.h.
Example
>>> from vidsrc import VideoSource
>>> video = VideoSource('test.avi', grayscale=False)
>>> len(video) # number of frames in video
48
>>> video.duration # length in s
1.6016
>>> video.framerate # frames per second
29.970089850329373
>>> video.shape # frames, height, width, color channels
(48, 64, 64, 3)
>>> frame = video[0] # access first frame
>>> frame = video[-1] # access last frame
>>> for frame in video:
... pass # do_something_with(frame)
