I've often wondered how easy it would be for people in the scene to rip Netflix or others streaming content. Isn't it as simple as getting the URL of the video player element in the browser and using cURL or wget?
It's not that simple. The video files are chopped up into pieces for streaming, so what you would download (assuming wget would handle the stream) are thousands of tiny files. You could reassemble them with ffmpeg, but first you'd need to decrypt them. It's the encryption that these leaked scripts take care of.
