ZeroDivisionError

[AndreLYL]

How to solve this Problem?
i used pip not pip3 to install opencv-python and video-to-ascii because it is not work

Traceback (most recent call last):
File "/home/andre/anaconda3/bin/video-to-ascii", line 10, in
sys.exit(main())

@AndreLYL I was checking the code and I found this line

time_delta = 1./fps

fps get its value from cv2.CAP_PROP_FPS, perhaps are you trying to use this tool with a image file instead of video file?

[TrizlyBear]

I have the same video, seems that cv2 can't get the FPS so it takes 0 as FPS, when I try setting the FPS manually it only echoes '

Same here, still not fixed

Same error here. I hope the following helps with your debug research:

1. System info

• Debian 10.7
• python3 : 3.7.3
• pip3 : 18.1

2. Installations performed:

$ sudo apt install python3-pip
$ pip3 install video-to-ascii
$ pip3 install opencv-python

Because I had the same module error scenario, I installed opencv-python as instructed here: #36

3. Command execution:

$ video-to-ascii -f 300-remix.mp4

4. Error dump:

5. ffprobe dump of used video file
