An end user's media player understands playback better than a content delivery network can from its limited server-side data. Common Media Client Data (CMCD) is an open specification that lets you include this expanded playback information as metadata in requests from your media player.
This behavior lets you leverage CMCD to:
- Prefetch segment URLs from your origin server to speed up delivery.
- Store data in logs to help with troubleshooting.
There are some prerequisites and steps you need to follow to add it. See the Adaptive Media Delivery documentation for complete details.
