WINBIO_E_NO_CAPTURE_DATA
WINBIO_E_NO_CAPTURE_DATA means a later processing step expected a captured sample, but the sensor adapter’s capture buffer was empty. Capture either did not complete or the sample was not passed through the pipeline.
What to check
- Confirm that a successful capture operation precedes matching, enrollment, or raw-data processing.
- Check cancellation, bad-capture, and device-state results before this error in the log.
- For an adapter implementation, verify the handoff from sensor capture to the engine pipeline.
