Notes
-----

The DirectShow IMediaDet interface is deprecated and may be removed from
future releases of Windows
(https://docs.microsoft.com/en-us/windows/desktop/directshow/imediadet).

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``.

Examples
--------

>>> 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)
