No Progress bar

[EScinema]

I wanted a progress bar so I made one for you guys but only on the run_video.py. Hopefully you guys add this its super simple, but makes waiting for it to finish a lot less of a guess. Thanks!

import cv2
import glob
import matplotlib
import numpy as np
import os

from depth_anything_v2.dpt import DepthAnythingV2

def progress_bar(current, total, remaining, bar_length=40):
    fraction = current / total

    arrow = int(fraction * bar_length - 1) * '-' + '>'
    padding = int(bar_length - len(arrow)) * ' '

    ending = '\n' if current == total else '\r'

    print(f'Progress: [{arrow}{padding}] {int(current)}/{int(total)} Time Remaining: {remaining[0]}', end=ending)```
