Hi, my friend submit a new PR, could we discuss the problem in here?

@yangqing-yq Hi, you can look at the new PR, which has solved this problem. In file "4DGaussians/scene/neural_3D_dataset_NDC.py", line 265, you can modify codes like:

videos = glob.glob(os.path.join(self.root_dir, "cam*.mp4"))

it worked! Thanks!
