VIDIOC_REQBUFS: Inappropriate ioctl for device

[wangyu0303]

Hello, When I finished train, how do I test or eval it? I got this issue. Can you Help me?

I will appreciate your help with this situation.
Thank you in advance.

Hi @wangyu0303, I guess something is wrong with your videos from ZeroDivisionError: integer division or modulo by zero caused by total_duration = (frameCount + fps - 1) // fps.

Thank you for your reply.
I owe you big time.
