class VideoFileFrameGenerator(telemetry.internal.image_processing.frame_generator.FrameGenerator)
`` | `Provides a Frame Generator for a video file. Sample Usage: generator = VideoFileFrameGenerator(sys.argv[1]).GetGenerator() for frame in generator: # Do something
Attributes:
_capture: The openCV video capture.
_frame_count: The number of frames in the video capture.
_frame_index: The frame number of the current frame.
_timestamp: The timestamp of the current frame.
_dimensions: The dimensions of the video capture.

Data descriptors inherited from telemetry.internal.image_processing.frame_generator.FrameGenerator:

Generator
  `Returns:
  A reference to the created generator.`

__dict__
  `dictionary for instance variables (if defined)`

__weakref__
  `list of weak references to the object (if defined)`

Data and other attributes inherited from telemetry.internal.image_processing.frame_generator.FrameGenerator:

__metaclass__ = <class 'abc.ABCMeta'>
  `Metaclass for defining Abstract Base Classes (ABCs).
  Use this metaclass to create an ABC. An ABC can be subclassed
  directly, and then acts as a mix-in class. You can also register
  unrelated concrete classes (even built-in classes) and unrelated
  ABCs as 'virtual subclasses' -- these and their descendants will
  be considered subclasses of the registering ABC by the built-in
  issubclass() function, but the registering ABC won't show up in
  their MRO (Method Resolution Order) nor will method
  implementations defined by the registering ABC be callable (not
  even via super()).`
