Diagnosing NS_E_WMPCORE_PLAYLIST_EVENT_EMPTY
This result is HRESULT 0xC00D10A7. At the playback core playlist event empty checkpoint it means the EVENT block contains no playable entries or references; the result belongs to the Windows Media playlist and metafile state machine, not to an unspecified Player failure.
Evidence that separates the result
| Result | Different boundary |
|---|---|
NS_E_WMPCORE_PLAYLIST_EVENT_ATTRIBUTE_ABSENT | A required attribute is absent from a playlist EVENT block |
NS_E_WMPCORE_PLAYLIST_STACK_EMPTY | The nested-playlist return path has no parent frame on the playlist stack |
NS_E_WMPCORE_CURRENT_MEDIA_NOT_ACTIVE | The requested action targets a Media object that is not the currently active item |
Representative case: The event name exists, but its content was removed during playlist generation. The example isolates only the producing component.
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.
