Video decomposition and synthesis using OpenCV

Decompose the video into images via OpenCV:

import cv2
import os

video = cv2.VideoCapture(r'F:\SuperResolution\BasicVSR_PlusPlus\data\test_video.mp4')
num = 0

while True:
    ret, frame = video.read()  # 读取视频帧

    if not ret:
        break

    frame = cv2.resize(frame, (1280, 720), interpolation=cv2.INTER_CUBIC)  # 调整图像大小
    cv2.imwrite(os.path.join(r'F:\SuperResolution\BasicVSR_PlusPlus\data\demo_000', '{}'.format(num).zfill(8)+'.png'), frame)  # 保存图像
    num += 1

video.release()
cv2.destroyAllWindows()

Merge images into video via OpenCV:

import cv2
import os

save_path = r'F:/SuperResolution/BasicVSR_PlusPlus/results/demo.avi'
fourcc = cv2.VideoWriter_fourcc(*'XVID')
fps = 24.0

out = cv2.VideoWriter(save_path, fourcc, fps, (1280, 720))  # 创建视频写入对象

path = r'F:\SuperResolution\BasicVSR_PlusPlus\results\demo_111'  # 存储图像的目录
lst = os.listdir(path)  # 图像名称列表

for name in lst:
    img_path = os.path.join(path, name)  # 图像路径
    frame = cv2.imread(img_path)  # 读取图像
    out.write(frame)  # 将图像写入视频

cv2.destroyAllWindows()
