Lesson of the Week: CMAF Proof of Concept

The Common Media Application Format (CMAF) is supposed to be the Holy Grail of streaming; one set of files that you can deliver to multiple output points. How well does it work today? This 3:47 video shows you.

I started by creating CMAF output in AWS Elemental MediaConvert. Why? Because they supply useful templates, have an easy to use UI, and it’s accessible to everyone with an Amazon account. The template created one set of media files and manifests for HLS and DASH, which I tested in:

JWPlayer test player (HLS and DASH)
Bitmovin test player (HLS and DASH)
Chrome (using the Native MPEG-DASH + HLS Player extension) (HLS and DASH)
Microsoft Edge (HLS only)

How did the players do? Watch the video and see. I will say that if you don’t need to protect your videos with DRM, CMAF is looking pretty functional right now.
