NS_E_WMPCORE_MEDIA_UNAVAILABLE
Where the Player stopped
Windows Media Player reports NS_E_WMPCORE_MEDIA_UNAVAILABLE (0xC00D10B3) when the media resource is currently unavailable at its local, removable or network location. The playback core media unavailable condition is owned by the core that resolves Player.URL, selects or builds a playback graph, chooses codecs and devices, prerolls media and advances between playlist items while reporting asynchronous errors.
An additional test is to record resolved path/URL, storage presence and access result at failure time; that evidence is more useful than reinstalling the Player or changing several unrelated settings at once.
Investigation order
- Start with the symbolic HRESULT; do not diagnose playback core media unavailable from the final dialog alone.
- Use this deciding observation for this condition: record resolved path/URL, storage presence and access result at failure time.
- Apply the smallest supported remedy for this condition: restore the resource or update the library/playlist to its current location.
The surrounding WMP state
Representative case: A playlist points to a removed memory card or disconnected share.
Inputs that distinguish the causes
| Field | What to record |
|---|---|
| What to verify | Record resolved path/URL, storage presence and access result at failure time |
| Artifact identity | Play state and transition immediately before failure for this reproduction |
| Runtime state | Selected graph/source/filter or codec identity and version for this reproduction |
| Owning object | Audio/video device identity and driver generation for this reproduction |
| Lower-level result | Ordered ErrorItem queue with errorCode, errorContext and media object for this reproduction |
| Correlation | Player.URL, current media sourceURL and resolved final URL for this reproduction |
Do not confuse it with nearby results
| Result | Different condition |
|---|---|
NS_E_WMPCORE_VIDEO_TRANSFORM_FILTER_INSERTION | The core cannot insert the video transform used for display adjustments into the current graph |
NS_E_WMPCORE_MISMATCHED_RUNTIME | The media was produced for, or parsed against, a runtime contract incompatible with the active WMP core |
NS_E_WMPCORE_BUSY | The Player core is occupied by an operation that prevents opening or playing this item now |
Verification after correction
What a real fix must change
The targeted correction for this condition is to restore the resource or update the library/playlist to its current location. Keep the original failing input until the same operation succeeds after one controlled change.
- Avoid installing broad codec packs before identifying the requested media subtype and missing component; it can destroy the artifact or state needed to explain this result.
- Avoid clearing the error queue or skipping to another playlist item before preserving the first failing media object; that can replace the original HRESULT with a secondary failure from another layer.
