encrypted HDS streaming

Wowza Streaming Engine
1

We have a requirement as follows

  1. be able to playback a protected video in a flash player via HDS streaming

  2. be able to download a protected video and play it in a desktop player

We do not want to keep multiple sets of video files for above 2 requirements on CDN. Hence, I want to know if wowza can play ezdrm encrypted video in a flash player via HDS streaming? I encrypt and package unprotected video with ezdrm packager. This protected content is fed to wowza media server for HDS streaming. Does wowza care if the video is DRM protected or not for HDS streaming?

Also, do you know if limelight cdn has any support for wowza media server?

This is not supported at present. The only option for HDS is HTTPS/SSL.

Wowza does not support encrypted files for Flash RTMP or Flash HTTP, so that is not an option.

Thanks for a quick response.

Given the above 2 requirements, is there any way to avoid keeping 2 sets of video files on the cdn server, one for protected download and other of protected streaming?

These are a few options that we have.

  1. 1 file = protected content for offline download and online progressive download

  2. 2 files = protected content for offline download and unprotected content fed to Flash Media Server for on-the-fly DRM and HDS streaming

  3. 2+ files = protected content for offline download and online RTMP multi bit rate via Flash Media Server

As option #1 is very inefficient due to progressive download, we have to rule it out. However, #2, #3 requires multiple set of files.

Do you have any suggestions or see any possibility of using wowza to alleviate this issue?
