NS_E_SPEECHEDL_ON_NON_MIXEDMODE
The failing boundary in the Encoder object model
The useful reading of NS_E_SPEECHEDL_ON_NON_MIXEDMODE (0xC00D1B92) is not merely the standard message shown above. It locates voice-codec optimization EDL is attached while the codec is not in mixed voice/audio mode inside preprocessing, analysis and multipass constraints.
Inverse telecine, time compression, image preprocessing, content analysis and two-pass encoding require access to particular source types and often require rereading or temporarily storing the source in a session that returns this result. Live, looping and device inputs impose additional restrictions.
Evidence that separates this code from a wrapper error
The underlying audio or video source may be healthy while the requested preprocessing workflow is impossible for that source lifecycle in a session that returns this result. For example, a speech-only preset is combined with a music-region definition file. Preserve the result distinction before a UI layer converts the result into a broad start, capture or profile failure.
| Field | What to preserve |
|---|---|
| Decisive values | audio codec, content mode and optimization EDL path/version |
| Producing object | source type, live/file flag, Repeat flag, pass count, temporary-storage setting, preprocessing filters, analyzer frame count, input frame rate, content EDL path and selected codec mode |
| Session correlation | the same source-group generation, audience index, object identity and callback sequence that produced this result |
| Lower-level evidence | the first COM, driver, file-system or codec HRESULT observed before the Encoder mapped the condition to this result |
| Controlled comparison | a known-good session that changes only the setting named in the speechedl on non mixedmode boundary |
Interpret the next measurement
| Observation | How to interpret it |
|---|---|
| Observation that supports it | The decisive evidence is audio codec, content mode and optimization EDL path/version. It confirms voice-codec optimization EDL is attached while the codec is not in mixed voice/audio mode in the same object generation. |
| Observation that points to an earlier failure | The recorded values satisfy the speechedl on non mixedmode rule, but a source, driver, COM activation or file operation returns a different HRESULT first. |
| Observation that points to a later failure | The Encoder passes this boundary (voice-codec optimization EDL is attached while the codec is not in mixed voice/audio mode), but a codec, archive or broadcast sink then fails in a subsequent stage. |
| Verification after correction | Apply this isolated change: select mixed voice/audio mode or remove the speech optimization EDL. The original speechedl on non mixedmode call should then advance past the same checkpoint. |
The operational impact of it is limited to the preprocessing, analysis and multipass constraints transition that owns voice-codec optimization EDL is attached while the codec is not in mixed voice/audio mode. In the representative case where a speech-only preset is combined with a music-region definition file, keep the first failing call and its object identity so a later wrapper cannot replace the speechedl on non mixedmode evidence.
Test the condition without rewriting the session
- Record
0xC00D1B92, it, the Encoder version and the exact API call or property access that returned it. - Export the current
.wmeor.prxconfiguration, then capture audio codec, content mode and optimization EDL path/version. - verify the preprocessing, analysis and multipass constraints precondition without changing the source, profile and output sink at the same time.
- Run one controlled comparison in which only this condition changes: select mixed voice/audio mode or remove the speech optimization EDL.
- After the change, recreate the affected Encoder object rather than assuming the existing graph discarded its earlier speechedl on non mixedmode state.
Interpret neighboring results carefully
| Result | Why it is a different boundary |
|---|---|
NS_E_NO_REPEAT_PREPROCESS | preprocessing or two-pass analysis requested while the source is configured to loop |
NS_E_NO_MULTIPASS_FOR_LIVEDEVICE | two-pass encoding from a live device is enabled without temporary source storage |
NS_E_NO_REALTIME_PREPROCESS | image preprocessing requested for a live source that cannot complete the required look-ahead or reread |
Resolution and verification
The direct repair for this occurrence is to select mixed voice/audio mode or remove the speech optimization EDL. Recreate the affected source group, profile or output object, repeat the same operation, and confirm that the first failing HRESULT no longer comes from the speechedl on non mixedmode checkpoint.
Do not enable several preprocessing features at once during diagnosis; validate the plain one-pass source first, then add one transformation with its required storage or analysis stage in a session that returns it.
