NS_E_WMPCORE_GRAPH_NOT_IN_LIST
Diagnosing NS_E_WMPCORE_GRAPH_NOT_IN_LIST
Windows Media Player reports this result (0xC00D108A) when the requested preroll/playback graph is not present in the core’s current graph list. The playback core graph not in list 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.
Evidence that separates the result
| Field | What to record |
|---|---|
| Decisive check | Record URL, graph generation and when the graph list was replaced or cleared |
| 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 |
Representative case: A delayed callback asks for a graph from the previous playlist item. The example isolates only the producing component.
Nearby results with different boundaries
| Result | Different boundary |
|---|---|
NS_E_WMPCORE_UNRECOGNIZED_MEDIA_URL | The supplied media URL cannot be interpreted as a supported path/protocol target |
NS_E_WMPCORE_NOBROWSER | WMP cannot invoke the browser required for a web-help or related URL action |
NS_E_WMPCORE_WEBHELPFAILED | The Player could not open the Web Help target associated with an error or command |
Verification
Repeat the original operation with a fresh owning object after the identified precondition is corrected. Treat this result as resolved only when that same operation passes this stage; preserve any later HRESULT as a separate failure.
