利用opencv-python 改变视频的分辨率

  利用opencv-python 改变视频的分辨率，代码如下

import os
import cv2
import argparse
from tqdm import tqdm

parser = ()
parser.add_argument('--video_path', default='data/video',  type=str)
parser.add_argument('--out_w', default=576, type=int)
parser.add_argument('--out_h', default=704, type=int)
args = parser.parse_args()

for video in tqdm((args.video_path)):
    path = args.video_path+video
    cap = (path)
    fps = (cv2.CAP_PROP_FPS)  # 保证存储之后视频的fps
    # print(fps)
    ou_dir = ('.')[0]+'new.mp4'
    videowriter = (ou_dir, cv2.VideoWriter_fourcc(*'mp4v'), fps, (576,704))

    s, img1 = ()
    while s:
        print("continue")
        try:
            _, img1 = ()
            img = (img1, (args.out_w, args.out_h), cv2.INTER_LINEAR)
            (img)
        except:
           break
