Pythonで動画の幅、高さ、fpsを取得、そこから1秒ごと(任意の間隔)に画像を生成する方法

Last updated at Posted at 2019-10-19

#動画の各種情報を取得7

import cv2

video_path = '動画のパス'
cap = cv2.VideoCapture(video_path)

width = cap.get(cv2.CAP_PROP_FRAME_WIDTH)

高さ

height = cap.get(cv2.CAP_PROP_FRAME_HEIGHT)

総フレーム数

count = cap.get(cv2.CAP_PROP_FRAME_COUNT)

fps

fps = cap.get(cv2.CAP_PROP_FPS)

print("width:{}, height:{}, count:{}, fps:{}".format(width,height,count,fps))

#1秒ごとに画像を生成

import cv2

video_path = "動画のパス"
cap = cv2.VideoCapture(video_path)

count = cap.get(cv2.CAP_PROP_FRAME_COUNT)
fps = cap.get(cv2.CAP_PROP_FPS)

print("width:{}, height:{}, count:{}, fps:{}".format(width,height,count,fps))

for num in range(1, int(count), int(fps)):
cap.set(cv2.CAP_PROP_POS_FRAMES, num)
cv2.imwrite("picture{:0=3}".format(int((num-1)/int(fps)))+".jpg", cap.read()[1])
print("save picture{:0=3}".format(int((num-1)/int(fps)))+".jpg")

cap.release()
