VideoInfo

class lib.video.VideoInfo(video_file: str, fast_count: bool = True, stream_index: int = 0, pts: list[int] | None = None, keyframes: list[int] | None = None)

Bases: object

Collects and stores information about video files

Parameters:

video_file (str) – Full path to a video file
fast_count (bool) – Whether to obtain the count of frames quickly, but inaccurately or slowly but accurately. If pts and keyframes are provided then the count will be derived from the provided pts file. Default: True
stream_index (int) – The stream index to select from the video file. Default: 0
pts (list[int] | None) – The Presentation Timestamps if available or None to retrieve from the video. Default: None
keyframes (list[int] | None) – The keyframe frame indices if available or None to retrieve from the video. Default: None

Attributes Summary

`count`	The number of frames in the video
`duration`	The duration of the video file in seconds
`keyframes`	The frame index of each key frame in the video
`keyframes_count`	The number of keyframes that exist in the video
`pts`	The Presentation Time Stamp for each frame in the video
