[Question] Save the video while run the play.py file

[chaofiber]

How can we save the video while playing a policy? During training I see there is an easy flag to enable the video recording. It would be very nice to have this option for evaluating policies.

This is fairly easy. Didn't get the time to add the video recorder wrapper to play.py file as well since we initially assumed people will run it with GUI anyway. Might be worth considering. Would you like to send an MR for this?
