NS_E_DRM_LICENSE_NOSVP

Interpret the security decision

At 0xC00D280B, NS_E_DRM_LICENSE_NOSVP records that the license requires a Secure Video Path capability unavailable in the selected environment. NS_E_DRM_LICENSE_NOSVP comes from Windows Media DRM client internals, whose state machine implements the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.

Before changing the machine, record video renderer, driver protection support and license requirement. The standard AllStat text is already shown above; this custom section concentrates on the object state and the evidence needed to separate NS_E_DRM_LICENSE_NOSVP from neighboring Windows Media errors.

Do not lose object identity

For NS_E_DRM_LICENSE_NOSVP, the important objects are DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Evidence for NS_E_DRM_LICENSE_NOSVP should correlate the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting failure.

The comparison is useful only if it preserves the fact that the license requires a Secure Video Path capability unavailable in the selected environment.

From HRESULT to cause

Preserve NS_E_DRM_LICENSE_NOSVP and 0xC00D280B before cleanup, fallback or another media item changes the context.
Run the direct check for NS_E_DRM_LICENSE_NOSVP: record video renderer, driver protection support and license requirement.
Compare the failure with a known-good case that changes only the property named by this condition: the license requires a Secure Video Path capability unavailable in the selected environment.
Apply the narrow correction for NS_E_DRM_LICENSE_NOSVP: use a compatible protected video path or appropriately licensed content.
Associate NS_E_DRM_LICENSE_NOSVP with its current Windows Media DRM client internals object and the requested action.
Repeat the same action with the same content/device identity and verify that NS_E_DRM_LICENSE_NOSVP is not replaced by another policy or trust failure.

How the operation should advance

The before/after comparison for NS_E_DRM_LICENSE_NOSVP has one controlled variable. Before correction, the license requires a Secure Video Path capability unavailable in the selected environment; after correction, the same workflow can use a compatible protected video path or appropriately licensed content. For NS_E_DRM_LICENSE_NOSVP, use a known-good counterpart only as a control; do not replace the failing artifact before its identifiers and hashes are recorded.

Keep the scope narrow

For NS_E_DRM_LICENSE_NOSVP, the established fact is that the license requires a Secure Video Path capability unavailable in the selected environment. For NS_E_DRM_LICENSE_NOSVP, that fact does not independently establish damaged media bytes, a missing decoder, a generally broken network, or invalid rights for every other action.

If the Player, encoder, setup program or device layer later emits a broader error, retain NS_E_DRM_LICENSE_NOSVP as the first specific result. The object and operation attached to NS_E_DRM_LICENSE_NOSVP are usually more diagnostic than a later cleanup or user-interface summary.

Values to compare

Field	Value for `NS_E_DRM_LICENSE_NOSVP`
Lower result	the earliest store, network, cryptographic, driver or provider status preceding the final NS_E_DRM_LICENSE_NOSVP wrapper
Owner	operation, API/callback, object or session identifier, and component/device version associated with NS_E_DRM_LICENSE_NOSVP
Direct check	record video renderer, driver protection support and license requirement
Policy input	requested action plus the exact license, certificate, profile, output or registration property evaluated by NS_E_DRM_LICENSE_NOSVP
Temporal state	trusted/system time, validity interval, request sequence and retry number when they influence NS_E_DRM_LICENSE_NOSVP

Distinguish from nearby results

Result	Why it points elsewhere
`NS_E_DRM_LICENSE_NOSAP`	the license requires Secure Audio Path capability that the active client cannot supply
`NS_E_DRM_LICENSE_NOWDM`	the protected audio license requires WDM audio drivers, but the active path is not WDM-capable
`NS_E_DRM_LICENSE_NOTRUSTEDCODEC`	the codec selected for protected content does not meet the license trust requirement

Fix and verify

Correct this layer directly and use a compatible protected video path or appropriately licensed content. For NS_E_DRM_LICENSE_NOSVP, success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.

While investigating NS_E_DRM_LICENSE_NOSVP, keep this restriction: Do not replace DRM binaries or registry state before recording their versions and signatures; otherwise a component mismatch and a damaged license object become indistinguishable.
Do not alter trusted time, revocation enforcement, certificate validation or output policy merely to suppress NS_E_DRM_LICENSE_NOSVP; that bypasses the decision instead of correcting its input.
Retain one failing artifact and one corrected artifact so the resolution of NS_E_DRM_LICENSE_NOSVP can be regression-tested.

Completion criterion

For the final NS_E_DRM_LICENSE_NOSVP test, keep the content KID or file hash, requested action, user/account, device identity and output route unchanged wherever they apply. The NS_E_DRM_LICENSE_NOSVP case is resolved only when the operation completes without this HRESULT and without a substitute failure from a neighboring license, trust, session or policy check.
