NS_E_HEADER_MISMATCH
Mechanism and scope
This result (0xC00D151F) marks a command is being applied to a different ASF/media-header generation than the component currently owns. The most useful interpretation starts with the Windows Media Services object that returned the HRESULT.
A server distribution path connects a data source, parser, media header and one or more data sinks; push publication adds an encoder-to-server control path, while client delivery uses a separate protocol and connection state. In the trace, trace input and output independently: source selection, parsing/header creation and sink selection are separate checkpoints.
Verification outcomes
| Controlled comparison | Use a known-good object of the same type and vary only the precondition described as “a command is being applied to a different ASF/media-header generation than the component currently owns”. |
A controlled correction
- Capture
0xC00D151F, the symbolic name, the exact API/administrative action and the first failure timestamp. - Preserve header identifier/hash, command context, stream switch, publishing-point restart and packetizer generation.
- Perform one isolated experiment: obtain the current header/context and issue the command against that exact generation.
Do not merge nearby HRESULT values
Primary distinction: stale presentation is client/presentation metadata; header mismatch is the media-header identity used by a server component.
| Nearby result | Different condition |
|---|---|
NS_E_PUSH_DUPLICATE_PUBLISHING_POINT_NAME | push setup attempts to create a publishing point whose valid name is already present. |
NS_E_WSX_INVALID_VERSION | the playlist declares a WSX version unsupported by the installed parser. |
NS_E_DATAPATH_NO_SINK | the constructed data path has no data writer capable of consuming its packets. |
Changes that do not establish the cause
- replaying a command captured before stream or header switch.
