python3--ffmpeg视频转换工具(一)

 4:假如提示ffmpeg为外部命令错误时，将ffmpeg的路径带上:

 代码如下:

def getImage(video_path):    base_path = os.path.join(os.path.join(os.getcwd(), "mp4"), video_path)    img_count = 1    crop_time = 0.0    try:while crop_time <= 22.0:  #转化22s的视频            os.system(‘D:\\ffmpeg-20191210-e73688e-win64-static\\bin\\ffmpeg -i %s -y -f image2 -ss %s  %s.jpg‘% (base_path, str(crop_time), str(img_count)))            img_count += 1            crop_time += 0.01  #每0.01秒截取一张照片        print(‘视频转化完成！！！‘)except Exception as e:print(e)def save():    dir_s = os.path.join(os.getcwd(), "image")if os.path.exists(dir_s):        shutil.rmtree(dir_s)    os.mkdir(dir_s)for root, dirs, tmps in os.walk(os.getcwd()):for file in tmps:if file.endswith("jpg") and os.path.exists(os.path.join(dir_s, file)) is False:                shutil.move(file, dir_s)video_path = "of2.mp4"getImage(video_path)save()
