NS_E_WSX_INVALID_VERSION
How to investigate NS_E_WSX_INVALID_VERSION
Mechanism and scope
This result (0xC00D151E) marks the playlist declares a WSX version unsupported by the installed parser. The code identifies a narrow server contract, so diagnosis should preserve the object generation and the first native return.
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.
Build a reproducible incident record
| Evidence | Why it matters for it |
|---|---|
| Decisive state | WSX root/version attribute, parser version, server version and any transformed copy. |
| Owning object | Record the server, publishing point, playlist, namespace node, plug-in or cache item that returned this result, 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 this result. |
| Controlled comparison | Use a known-good object of the same type and vary only the precondition described as “the playlist declares a WSX version unsupported by the installed parser”. |
| Security-sensitive data | Log identifiers, lengths, hashes and redacted URLs where possible; do not publish passwords, authorization files or unrestricted client data. |
Comparison with adjacent states
Primary distinction: playlist parse failure is generic syntax/parse failure; invalid version identifies compatibility before full interpretation.
| Nearby result | Different checkpoint |
|---|---|
NS_E_HEADER_MISMATCH | Compare its own symbolic boundary and the first failing call; it must not be grouped automatically with it. |
NS_E_NO_NEW_CONNECTIONS | Relative to it, this neighboring result belongs to another state or validation branch even when the user-visible symptom is similar. |
NS_E_PUSH_DUPLICATE_PUBLISHING_POINT_NAME | Use the object type and operation sequence to determine which result is authoritative. |
Code-specific failure anatomy
In a representative incident, the server reaches the playlist declares a WSX version unsupported by the installed parser and rejects the operation before the caller can safely assume the next stage occurred. The incident record should therefore join WSX root/version attribute, parser version, server version and any transformed copy with the object generation and the exact administrative or protocol request.
A useful negative control is convert the document to the supported WMS SMIL/WSX version or install the intended parser. 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 removing the version while keeping newer unsupported elements. That action does not test the distinction that matters here: playlist parse failure is generic syntax/parse failure; invalid version identifies compatibility before full interpretation. This distinction is also why monitoring should retain the symbolic name instead of storing only a generic COM failure.
A controlled correction
- Capture
0xC00D151E, it, the exact API/administrative action and the first failure timestamp. - Preserve WSX root/version attribute, parser version, server version and any transformed copy.
- confirm that the object still belongs to the current WMServer, publishing-point or presentation generation.
- Perform one isolated experiment: convert the document to the supported WMS SMIL/WSX version or install the intended parser.
- 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.
Keep the post-fix server event and object status so a later downstream HRESULT is not mistaken for recurrence of this one.
Changes that do not establish the cause
- removing the version while keeping newer unsupported elements.
- do not erase the first HRESULT by repeatedly clicking Apply; later calls can replace the thread error information and hide the component that rejected the operation.
- Do not suppress it or replace it with a generic “media server error”; retain the symbolic code and owning operation in telemetry.
Reading the second result
| Retest observation | Interpretation |
|---|---|
| The same call still returns it | 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 it, 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. |
