【Python】動画をコマ送りで見る方法をOpenCVで実装

Posted at

概要

動画をじっくりしっかり見たい!と思っても、なかなか
1コマ1コマ止めながらとか、**ズームしたい!**ってできませんよね。
動画の細かい部分を見たい時があったので、デバッグ用として作成しました!
(エラー処理は超ゆるいです)

使い方

次のコマに進めるには何かしらのキーを押さないといけない。
キーを押すまではimshowによりズームなり何なり可能。
"q"で再生終了。

ソースコード

debugVideo.py
import cv2

video = cv2.VideoCapture("output.mp4")

while video.isOpened():

    ret, frame = video.read()

    cv2.imshow("Preview", frame)

    if cv2.waitKey() & 0xFFF == ord('q'):
        break

video.release()
