We maintain an existing iOS/tvOS App Store application that uses AVFoundation for authenticated streaming playback.

One upstream provider supplies some account-entitled playback sessions as fragmented MP4 using ISO Common Encryption scheme cenc (AES-CTR). The provider controls the rendition, and no corresponding cbcs rendition is available to our client.

We understand that Apple’s documented FairPlay Streaming path supports cbcs. We identified com.apple.coremedia.allow-mpeg4streaming as relevant to this playback case, but the entitlement is undocumented and does not appear under Capability Requests for our App ID.

Apple Developer Support was unable to identify the request process and recommended posting this question in the forums and filing Feedback Assistant report FB24649355.

Could an Apple engineer clarify:

Is this entitlement available to third-party iOS/tvOS applications?
If so, what is the official request process?

We can provide additional technical information privately if an Apple engineer needs it.

Additional technical detail for the reviewing team:

On current iOS 26 and tvOS 26 builds, playback of the provider-supplied fragmented-MP4 HLS track (initialization segment declaring ISO/IEC 23001-7 cenc, AES-CTR) fails with CoreMediaErrorDomain -12927 during track format evaluation — before any content-key request reaches the application.

The content provider’s own App Store tvOS application plays these same renditions on standard hardware, so the capability appears to be grantable to third parties for this use case.

We are not seeking FairPlay Streaming deployment credentials or access to plaintext content keys — only the capability assigned to our Team ID/App ID.

A definitive determination in either direction would let us plan accordingly.

We can provide a reproducible sample, media metadata, and diagnostic logs privately on request.
