Manifest Manipulation can be optionally added
This lets you enhance the viewing experience by individualizing Apple HTTP Live Streaming (HLS) video quality to best suit your end user's devices.
You can add Manifest Personalization ("MPer") to your AMD configuration to personalize distribution of your HLS media. When a request is sent to a property hostname that's been set in your AMD configuration and it matches the criteria set for a rule that includes MPer for HLS, a manifest is generated "on-the-fly." This manifest determines the appropriate video quality content for the requesting device.
