У меня есть программа Tkinter.Мне нужен встроенный видеопроигрыватель в Tkinter, или же у меня есть возможность управления воспроизведением видео непосредственно в Tkinter.Моя цель - сохранить позиции наведения мыши на объекте интереса в данном видео.

Вот [ссылка] [https://solarianprogrammer.com/2018/04/21/python-opencv-show-video-tkinter-window/], из которой я получил основной код.
Я попробовал решения, упомянутые в этой ссылке , а также здесь , но все равно не помогло с проблемой.
Когда я это сделаю: import vlc
Я все еще получаю следующую ошибку:
Traceback (most recent call last):
File "<ipython-input-6-7c36fff9a8c5>", line 1, in <module>
import vlc
File "vlc.py", line 203, in <module>
dll, plugin_path = find_lib()
File "vlc.py", line 173, in find_lib
dll = ctypes.CDLL(libname)
File "C:\Anaconda2\envs\py27\lib\ctypes\__init__.py", line 362, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found`
Ценю любую помощь.Заранее спасибо.
