Saving captured frames to separate folders

Question

Currently working on extracting frames from videos and have noticed that the images get overwritten. Would be nice to create a folder for each of the captured frames but I’m unsure how to do that.

data_folder = r"C:UsersjagacDownloadsData"
sub_folder_vid = "hmdb51_org"
path2videos = os.path.join(data_folder, sub_folder_vid)

for path, subdirs, files in os.walk(path2videos):
    for name in files:
        vids = os.path.join(path, name)

        cap = cv2.VideoCapture(vids)
        i = 0
        
        frame_skip = 10
        frame_count = 0

        while(cap.isOpened()):
            ret, frame = cap.read()
            if ret == False:
                break
            
            if i > frame_skip - 1:
                frame_count += 1
                
                path2store= r"C:UsersjagacOneDriveDocumentsCSC578finalHumanActionClassifierimages"
                os.makedirs(path2store, exist_ok= True)
                path2img = os.path.join(path2store, 'test_' + str(frame_count*frame_skip) + ".jpg")
                cv2.imwrite(path2img, frame)
                
                i = 0
                continue
            i += 1 
        cap.release()
        cv2.destroyAllWindows()

The problem is that you’re not incorporating name into your path, so each video is overwriting the previous. You can either add the file name to path2img, or add name to the path2store variable before you make the directory.
