NS_E_WSX_INVALID_VERSION
Mechanism and scope
This result (0xC00D151E) marks the playlist declares a WSX version unsupported by the installed parser.
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.
Build a reproducible incident record
| 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”. |
Comparison with adjacent states
Primary distinction: playlist parse failure is generic syntax/parse failure; invalid version identifies compatibility before full interpretation.
| Nearby result | Different condition |
|---|---|
NS_E_HEADER_MISMATCH | a command is being applied to a different ASF/media-header generation than the component currently owns. |
NS_E_NO_NEW_CONNECTIONS | the server currently refuses additional client connections. |
NS_E_PUSH_DUPLICATE_PUBLISHING_POINT_NAME | push setup attempts to create a publishing point whose valid name is already present. |
Code-specific failure anatomy
A representative occurrence is when the playlist declares a WSX version unsupported by the installed parser. Capture WSX root/version attribute, parser version, server version and any transformed copy together with the object instance and the exact administrative or protocol request.
For a useful negative control, convert the document to the supported WMS SMIL/WSX version or install the intended parser.
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.
A controlled correction
- Capture
0xC00D151E, the symbolic name, the exact API/administrative action and the first failure timestamp. - Preserve WSX root/version attribute, parser version, server version and any transformed copy.
- Perform one isolated experiment: convert the document to the supported WMS SMIL/WSX version or install the intended parser.
Changes that do not establish the cause
- removing the version while keeping newer unsupported elements.
