Streaming video

Due to self isolation I am unable to see my Son, we used to meet up twice a week to watch videos together ( currently Viking’s and Walking Dead )

Can anyone suggest a program ( or method ) whereby I can play the video and my Son can watch it at the same time at his home, preferably with audio and video via a Mike & Webcam. ( picture in picture would be perfect ) I found some programs, but they rely on Both participants having the same video and both playing it simultaneously.

There must be a way.....help me please, will help me keep some sanity in this awful world we currently live in.

thanks

Didn’t think of Skype, as it shares the screen rather than stream the video, I assume the quality will be lower ? Also whilst watching and sharing a video, can I have a picture in picture to see the other person and hopefully talk to him during the movie....thanks
