NS_E_INCORRECTCLIPSETTINGS
The failing boundary in the Encoder object model
The useful reading of NS_E_INCORRECTCLIPSETTINGS (0xC00D1B7C) is not merely the standard message shown above. It locates validation of crop margins against source dimensions inside video capture and compressor negotiation.
A live video source passes through device opening, capture-format negotiation, optional clipping and preview-window setup before an encoder codec accepts the frames in a session that returns this result. Width, height, pixel format and driver state belong to this boundary at the incorrectclipsettings checkpoint.
Evidence that separates this code from a wrapper error
Seeing a device in enumeration or obtaining a preview frame does not establish that the requested capture format can be delivered continuously to the encoder in a session that returns this result. For example, saved crop values from a larger camera mode remove the entire image after resolution changes. 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 | source width/height and left, top, right and bottom clip values after all UI conversions |
| Producing object | device moniker, driver version, requested and native width/height, frame rate, BITMAPINFOHEADER compression and bit depth, preview state, source-plug-in result and first driver error |
| 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 incorrectclipsettings boundary |
Interpret the next measurement
| Observation | How to interpret it |
|---|---|
| Observation that supports it | The decisive evidence is source width/height and left, top, right and bottom clip values after all UI conversions. It confirms validation of crop margins against source dimensions in the same object generation. |
| Observation that points to an earlier failure | The recorded values satisfy the incorrectclipsettings 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 (validation of crop margins against source dimensions), but a codec, archive or broadcast sink then fails in a subsequent stage. |
| Verification after correction | Apply this isolated change: choose nonnegative margins whose sums leave a positive capture rectangle. The original incorrectclipsettings call should then advance past the same checkpoint. |
The operational impact of it is limited to the video capture and compressor negotiation transition that owns validation of crop margins against source dimensions. In the representative case where saved crop values from a larger camera mode remove the entire image after resolution changes, keep the first failing call and its object identity so a later wrapper cannot replace the incorrectclipsettings evidence.
Test the condition without rewriting the session
- Record
0xC00D1B7C, it, the Encoder version and the exact API call or property access that returned it. - Export the current
.wmeor.prxconfiguration, then capture source width/height and left, top, right and bottom clip values after all UI conversions. - verify the video capture and compressor negotiation precondition without changing the source, profile and output sink at the same time.
- Run one controlled comparison in which only this condition changes: choose nonnegative margins whose sums leave a positive capture rectangle.
- After the change, recreate the affected Encoder object rather than assuming the existing graph discarded its earlier incorrectclipsettings state.
Interpret neighboring results carefully
| Result | Why it is a different boundary |
|---|---|
NS_E_VIDCAPDRVINUSE | detection of an already active stream on the same video driver |
NS_E_NO_DATAVIEW_SUPPORT | request for Encoder Video panel data from a source or output path that cannot expose preview samples |
NS_E_VIDCAPCREATEWINDOW | creation of the hidden or visible capture window required by the legacy capture path |
Resolution and verification
The direct repair for this occurrence is to choose nonnegative margins whose sums leave a positive capture rectangle. 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 incorrectclipsettings checkpoint.
Do not keep retrying an unstable capture driver in the same process after preserving the first error; close the graph and test one known-native format in a fresh process in a session that returns it.
