NS_E_INVALID_PUSH_PUBLISHING_POINT: owning object, evidence and recovery
Mechanism and scope
This result (0xC00D151B) marks the push target is absent, wrong type or otherwise unsuitable for encoder push. It belongs to the server-side control path, not to a generic local media-player failure.
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 a this result trace, trace input and output independently: source selection, parsing/header creation and sink selection are separate checkpoints. The decisive question is whether the live object and values match that boundary; the base AllStat description alone does not reveal the object generation, selected plug-in or lower-level failure.
Reading the second result
| Retest observation | Interpretation |
|---|---|
| The same call still returns this result | The rejected precondition has not changed, or the caller is still using an old object/configuration generation. |
| The operation advances and a later code appears | The boundary was cleared. After this result, diagnose the new code at its own source, parser, sink, network or client stage. |
| A new object succeeds while the retained object fails | Object lifetime or stale context is part of the incident; update lifecycle handling rather than applying a machine-wide repair. |
| Only one publishing point, playlist, cache key or plug-in fails | The evidence favors object-specific configuration or content over a server-wide outage. |
Code-specific failure anatomy
In a representative incident, the server reaches the push target is absent, wrong type or otherwise unsuitable for encoder push and rejects the operation before the caller can safely assume the next stage occurred. The incident record should therefore join server name, publishing-point name, point type, push data source configuration, ACL and current owner connection with the object generation and the exact administrative or protocol request.
A useful negative control is verify the target through the server object model and create/configure a true push broadcast point before reconnecting the encoder. If that change advances the same it call, the result supports this boundary. If it remains, return to the first lower-level event instead of broadening the repair.
The tempting but misleading response is testing only the public playback URL; encoder push uses a different direction and authorization path. That action does not test the distinction that matters here: duplicate push name is creation-time collision; invalid push point rejects the selected target. This distinction is also why monitoring should retain the symbolic name instead of storing only a generic COM failure.
What to record before changing anything
| Evidence | Why it matters for it |
|---|---|
| Decisive state | server name, publishing-point name, point type, push data source configuration, ACL and current owner connection. |
| Owning object | Record the server, publishing point, playlist, namespace node, plug-in or cache item that returned it, including its creation or restart time. |
| First lower-level result | Preserve the earliest Win32, socket, COM, parser or plug-in event before the HRESULT; later wrappers can map several causes to it. |
| Controlled comparison | Use a known-good object of the same type and vary only the precondition described as “the push target is absent, wrong type or otherwise unsuitable for encoder push”. |
| Security-sensitive data | Log identifiers, lengths, hashes and redacted URLs where possible; do not publish passwords, authorization files or unrestricted client data. |
A controlled correction
- Capture
0xC00D151B, it, the exact API/administrative action and the first failure timestamp. - Preserve server name, publishing-point name, point type, push data source configuration, ACL and current owner connection.
- confirm that the object still belongs to the current WMServer, publishing-point or presentation generation.
- Perform one isolated experiment: verify the target through the server object model and create/configure a true push broadcast point before reconnecting the encoder.
- Repeat the original the operation through the same protocol and service account; do not substitute a different client-side test.
- After it, verify the expected next state and retain any later HRESULT as a separate pipeline result.
For automated tests, assert both the HRESULT and the resulting publishing-point, playlist, plug-in or archive state.
Comparison with adjacent states
Primary distinction: duplicate push name is creation-time collision; invalid push point rejects the selected target.
| Nearby result | Different checkpoint |
|---|---|
NS_E_CRITICAL_ERROR | Compare its own symbolic boundary and the first failing call; it must not be grouped automatically with it. |
NS_E_INVALID_PUSH_TEMPLATE | Relative to it, this neighboring result belongs to another state or validation branch even when the user-visible symptom is similar. |
NS_E_NO_NEW_CONNECTIONS | Use the object type and operation sequence to determine which result is authoritative. |
Changes that do not establish the cause
- testing only the public playback URL; encoder push uses a different direction and authorization path.
- avoid changing the publishing point, protocol, content and plug-in set in one test., such a test cannot show which precondition cleared the code.
- Do not suppress it or replace it with a generic “media server error”; retain the symbolic code and owning operation in telemetry.
