视频按每100帧存一个文件夹，处理完再图片转视频

video转图片

import cv2
from PIL import Image
import numpy as np
import os

# cap = cv2.VideoCapture("/home/zhanglu/tao/contain/tlt_infer_testing/deepstm_result/result.mp4") # 获取视频对象
cap = cv2.VideoCapture("/media/zhanglu/ff11386b-3ffe-4e34-a2f7-35bd45cb2e72/data/realbsvsr/0629.mov")  # 获取视频对象

isOpened = cap.isOpened  # 判断是否打开
# 视频信息获取
fps = cap.get(cv2.CAP_PROP_FPS)
imageNum = -1
sum=0
while (isOpened):
    sum+=1
    (frameState, frame) = cap.read()  # 记录每帧及获取状态
    # if frameState == True and (sum % timef==0):
    if frameState == True:
        frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
        frame = Image.fromarray(np.uint8(frame))
        frame = np.array(frame)
        # RGBtoBGR满足opencv显示格式
        frame = cv2.cvtColor(frame, cv2.COLOR_RGB2BGR)
        imageNum = imageNum + 1
        name = str(imageNum).zfill(8)
        fileName = 'data/part/part1/' + str(name) + '.png'  # 存储路径
        cv2.imwrite(fileName, frame, [cv2.IMWRITE_JPEG_QUALITY, 100])
        print(fileName + " successfully write in")  # 输出存储状态

    elif frameState == False:
        break
print('finish!')
cap.release()

图片按每个文件夹00000000.png～00000099.png存放

import os,cv2
path='imgs/all/'
new_path='imgs/partaa/'
dir=os.listdir(path)
count=0
for name in dir:
    a=cv2.imread(path+name)
    name_i=int(name.strip('.png'))
    res=int(name_i/100)
    for i in range(99):
        if i==0:
            continue
        if res>=i and res<i+1:
            new_path_1=new_path+'part'+str(res+1)
            if not os.path.exists(new_path_1):
                os.mkdir(new_path_1)
            new_name_i=name_i-100*res
            name_last = str(new_name_i).zfill(8)+'.png'
            os.rename(os.path.join(path,name),os.path.join(new_path_1,name_last))

处理完再把这些文件夹存成视频

import os,cv2
video = cv2.VideoWriter('/media/zhanglu/0bb0d537-0b35-45bf-94ec-9def4a6dd599/zhanglu/RealBasic/BasicVSR_PlusPlus-master/ss.mp4', cv2.VideoWriter_fourcc(*"mp4v"), 30, (1408,792)) #创建视频流对象-格式一
path='/media/zhanglu/0bb0d537-0b35-45bf-94ec-9def4a6dd599/zhanglu/RealBasic/BasicVSR_PlusPlus-master/results/'
for i in range(1,35):
    path_new = path+ 'demo_'+str(i)
    dir=os.listdir(path_new)
    for j in range(100):
        for name in dir:
            if j==int(name.strip('.png')):
                img=cv2.imread(os.path.join(path_new,name))
                video.write(img)  # 向视频文件写入一帧--只有图像，没有声音
video.release()
cv2.waitKey()
