NS_E_DRM_SOURCEID_NOT_SUPPORTED
Interpret the security decision
At 0xC00D280E, NS_E_DRM_SOURCEID_NOT_SUPPORTED records that the license/content source identifier requires a client feature not implemented by this DRM version. The subsystem producing this result is Windows Media DRM client internals, not the media decoder; it performs the client DRM engine that initializes security components, validates content and license identifiers, performs individualization, manages license chains and coordinates protected playback capabilities.
The shortest path to a defensible diagnosis is to capture source ID, content header version and client DRM generation.
Values to compare
| Field | Value |
|---|---|
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by this result |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence this result |
| Lower result | the earliest store, network, cryptographic, driver or provider status preceding the final it wrapper |
| Owner | operation, API/callback, object or session identifier, and component/device version associated with it |
| Direct check | capture source ID, content header version and client DRM generation |
Do not lose object identity
It is meaningful only while the following state remains associated with one operation: DRM component version, KID, content header signature, license chain, uplink license, individualization state, portable-device registrations and local configuration. Preserve the KID and header hash, DRM component version, individualization status, license-chain identifiers, registry/configuration lookup and the first client callback reporting failure for it.
The producing layer has not made a claim about every media operation; it has only established that the license/content source identifier requires a client feature not implemented by this DRM version.
How the operation should advance
A useful failure model for it links cause and recovery: the license/content source identifier requires a client feature not implemented by this DRM version. Verify that model when you capture source ID, content header version and client DRM generation, then make the smallest change needed to use a newer compatible client or obtain content issued for the supported DRM generation. 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
The established fact is that the license/content source identifier requires a client feature not implemented by this DRM version. 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 it as the first specific result. The object and operation attached to it are usually more diagnostic than a later cleanup or user-interface summary.
From HRESULT to cause
- Preserve it and
0xC00D280Ebefore cleanup, fallback or another media item changes the context. - Apply the narrow correction for it: use a newer compatible client or obtain content issued for the supported DRM generation.
- Associate it with its current Windows Media DRM client internals object and the requested action.
- Run the direct check for it: capture source ID, content header version and client DRM generation.
- Compare the failure with a known-good case that changes only the property named by this condition: the license/content source identifier requires a client feature not implemented by this DRM version.
- Repeat the same action with the same content/device identity and verify that it is not replaced by another policy or trust failure.
Distinguish from nearby results
| Result | Why it points elsewhere |
|---|---|
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 |
NS_E_DRM_NEEDS_UPGRADE_TEMPFILE | a pending DRM component upgrade depends on a temporary upgrade artifact that cannot be used as expected |
Fix and verify
Repair the owner of the check: use a newer compatible client or obtain content issued for the supported DRM generation. Success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- Evidence for it is easy to destroy; 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 it; that bypasses the decision instead of correcting its input.
- Retain one failing artifact and one corrected artifact so the resolution of it can be regression-tested.
Completion criterion
For the final it test, keep the content KID or file hash, requested action, user/account, device identity and output route unchanged wherever they apply.
