Pls do anybody have any idea of a company that provides video streaming services, which will not allow users to download the videos. Like the video tutorials of udemy.com. Their videos are streamed. You cant download the videos. A client wants to have a video tutorial website but he doesnt want users to download the videos. He wants them to always watch the videos online.
Which company is streaming the udemy.com videos? Or is there any other services out there like open source or paid service?
