CVVideoPlayerLite

A lightweight OpenCV video player designed to facilitate frame analysis. It features real-time on-screen data including timestamp, frame index, and playback performance.

import cv2 as cv

from video_player import VideoPlayer, LSize

player = VideoPlayer('../videos/5911716-hd_1920_1080_25fps.mp4')
player.resize(LSize.SD)
player.run()

Features

1. Resize OpenCV windows to SD, HD, or FHD resolutions (landscape or portrait). Example: player.resize(LSize.SD).
2. Callback support to handle external routines. Example: player.run(lambda image: cv.cvtColor(image, cv.COLOR_BGR2GRAY)).
3. Start video playback from a specific timestamp. Example: player.run(start=1000).

Controls

• SPACE: play or pause the video.
• ⬅️/➡️: step one frame backward or forward.
• ⬇️/⬆️: jump to first or last frame.
