# 視訊分解成圖片 import cv2 cap = cv2.VideoCapture("22.mp4") # 獲取開啟的控制代碼 isOpened = cap.isOpened # 判斷是否開啟 print(isOpened) fps = cap.get(cv2.CAP_PROP_FPS) width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)) height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)) print(fps,width,height) i = 0 while(isOpened): if i == 10: break else: i = i+1 (flag,frame) = cap.read() fileName = "image" +str(i) +".jpg" print(fileName) if flag == True: cv2.imwrite(fileName,frame,(cv2.IMWRITE_JPEG_QUALITY,100)) print('end') #圖片合成視訊 import cv2 img = cv2.imread("1.jpg") imgInfo = img.shape size = (imgInfo[0],imgInfo[1]) print(size) videoWrite = cv2.VideoWriter("33.mp4",-1,5,size)# 寫入物件的建立 # 檔名稱 2. 編碼器 3.幀率 4. size for i in range(1,10): fileName = "image"+str(i)+".jpg" img = cv2.imread(fileName) videoWrite.write(img) # 寫入方法 print('end')
