Sometime got stuck

[jiarongqiu]

I used the following snippet, but sometimes got stuck at some videos.
I checked the Memory and Graphics Card, neither of them is full.

	num=100000
	start=time.time()
	video_list=sorted(os.listdir(path))[:num]
	num = min(len(video_list),num)
	for video_name in video_list:
		video_path = os.path.join(path,video_name)
		print (video_path)
		loader = pynvvl.NVVLVideoLoader(device_id=0, log_level='error')
		n_frames = loader.frame_count(video_path)
		print('Number of frames:', n_frames)
	duration = time.time()-start
	print(duration,duration/num)
