Method Details [hide private]

__init__(self, filename, size=None)
(Constructor)

source code 

The basic video class that is used to play back a movie file.

Parameters:
  • filename - The full path name of the video file including extension. Also, with current versions of OpenCV, this can be a url to a network IP camera, but you will need to consult your IP camera manufacturer's documentation as url formats vary.
Overrides: object.__init__

Note: The following is an example of using the Video class with an IP camera. The rtsp url is for a linksys WVC54GCA IP camera. The ip address will need to be changed as appropriate for your local network. Other model cameras use different urls. It can take a few seconds for the feed to be established. cam_url = "rtsp://192.168.2.55/img/video.sav" vid = Video(cam_url) vid.play()

__iter__(self)

source code 

Return an iterator for this video

Overrides: VideoInterface.__iter__

query(self)

source code 

Must be overridden to implement the specific frame-grabbing required by different video sources.

Overrides: VideoInterface.query
(inherited documentation)
