How to protect the viewing of video from the site?

Question

Video

There is an educational project.
Guitar lessons.
There is a private office.
The student buys access to the course and opens access to the lessons of the course.
All done only from can not protect the video.
We thought to do it through youtube, but it's very easy to download it in many ways.
Then via google drive.
Upload a video to a google drive and then pull it out in parallel to encrypt the link, or it will not download anyway because there will be no api key.
But here is the difficulty, I just don’t understand how to pull the video from google drive.
Maybe someone has already done such a task?
And maybe someone will tell you an easier option, how to protect video viewing?
PS Please do not give links to the google drive documentation, it has already bullied me. It's unclear.

Answer 1

No way. They will write to the edge from the screen. I want the illusion of protection - write your own player, which will receive video from the server in parts of N kilobytes.

Answer 2

uppod.ru try this one, it is inserted on popular sites with movie libraries

Answer 3

There are no methods of full-fledged protection and cannot be fundamentally, so be guided by how cost-effective it is for the "intruder", in your case one of the various Flash player libraries will suffice, or write your own.
