There are some known issues that apply to the use of watermarking with AMD. Review them before adding this functionality to your property.
Akamai needs to deliver HLS media manifests.
Delivery of watermarked content follows a specific scheme:
Akamai needs to update HLS manifests to properly perform the switch and deliver segments based on what's defined in the WMT.
There will be a footprint increase when watermarking is enabled.
Watermarking generates two separate versions of a media file to support its variant A to B switch model. So, storage on your origin will be impacted.
Watermarking can't be applied in Multi-CDN environments.
This feature won't work as intended in a multi-CDN environment because its functionality is unique to the Akamai CDN. If a request was to be switched mid-stream to another CDN, it would need a version of watermarking that mirrors Akamai's.
Prefetching is not recommended.
Our Prefetching implementation uses an origin-assist model that is not optimal with watermarking. As a result, AMD can't properly apply the Segmented Media Streaming - Prefetch behavior and the Watermarking behavior to a single request. Avoid including both behaviors in the same rule. Also, don't apply either behavior in the Default Rule, if the other exists in a subsequent rule in your property. This is because the Default Rule applies to all requests.
Media Services Live isn't supported.
Watermarking is currently only supported for use with on-demand media. Your Origin Server needs to be set to either "Your Origin" or "NetStorage."
AMD Failover doesn't work with Watermarking.
Currently, AMD failover does not work if you also include Watermarking. This should be fixed with an upcoming release.
Range requests are not supported.
This can cause a range mismatch. Arbitrary range requests are a security violation when requesting a watermarked stream.
