Error while using RandomResizedCropVideo

I started using the new video transformations by downloading the video transformations source code (seems like it doesn't appear when trying to upgrade via pip).

The transformation I'm trying to use is:

def build_transforms():
    mean = [0.485, 0.456, 0.406]
    std = [0.229, 0.224, 0.225]
    res = transforms.Compose([transforms_video.ToTensorVideo(),
                              transforms_video.RandomResizedCropVideo(224),
                              transforms_video.RandomHorizontalFlipVideo(),
                              transforms_video.NormalizeVideo(mean=mean, std=std)
                              ])

    return res

This composition raises an error while trying to transform a video clip (It doesn't happen if I remove transforms_video.RandomResizedCropVideo(224)):

Start at the video transformation implementation around transforms_video.py line 78, then compare its get_params call with torchvision/transforms/transforms.py. Reproduce the RandomResizedCropVideo(224) failure in the reported Compose pipeline and trace the clip shape and type reaching the crop transform. Done means the transform runs without the reported TypeError while preserving the behavior of the other listed video transforms.
