read_video_timestamps

torchvision.io.read_video_timestamps(filename: str, pts_unit: str = 'pts') → Tuple[List[int], Optional[float]]

List the video frames timestamps.

Warning

In the near future, we intend to centralize PyTorch’s video decoding capabilities within the torchcodec project. We encourage you to try it out and share your feedback, as the torchvision video decoders will eventually be deprecated.

Note that the function decodes the whole video frame-by-frame.

Parameters:

• filename (str) – path to the video file

• pts_unit (str, optional) – unit in which timestamp values will be returned either ‘pts’ or ‘sec’. Defaults to ‘pts’.

Returns:

presentation timestamps for each one of the frames in the video. video_fps (float, optional): the frame rate for the video

Return type:

pts (List[int] if pts_unit = ‘pts’, List[Fraction] if pts_unit = ‘sec’)
