[bug] video player won't work
EDIT: the flask install part is the minor part of the bug, major part in next comment)
fresh pip install hub, tried to play from a video sample (cool API btw), says flask needs to be installed

after pip installing, actually the video won't play (ubuntu 20.04, using a conda environment on python version 3.7.13, on a jupyter notebook in visual studio code)
all i did was create an mp4 sample compressed tensor, added one video using hub.read (~100MB video) and tried to use the in-notebook player:

yoooo but using ds.visualize works! damn. that shits cool
@FayazRahman this was on a local jupyter notebook instance
@nollied Tried on jupyter notebook and it works. But there seems to be an issue with VScode. I tried playing a video directly from a link and it didnt work:
import IPython
html = f"""<video alt="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4" width=500 controls autoplay seek loop>
<source src="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4" type="video/mp4">
</video>
"""
IPython.display.HTML(html)
Closing since its an issue with VScode.
