Playing encrypted video

Question

What I want to do is next: We need to protect the video content(encrypt it) and be able to play it.

Tricky part is that we do not want to load everything into memory

Answer 1

The best choice for this today is:

1. Use S3, CloudFront, MediaConvert
2. Convert MP4 into AES-128 bit encrypted HLS stream (using MediaConvert) using an encryption key (customer-managed is easier)
3. Stream it on your website using VideoJS or other video player that supports playing encrypted HLS streams

If you have WordPress, you could also use a commercial plugin that creates and plays encrypted videos.
