ippStsFIRMRFactorErr
FIRMR routines use a multirate FIR structure where the factor controls interpolation or decimation steps. A non-positive factor cannot select a valid phase sequence.
Validate the resampling ratio and the FIRMR initialization parameters together; the processing call inherits that contract.
Check these details for ippStsFIRMRFactorErr
- The factor used at FIRMR initialization.
- Coefficient layout for the expected number of phases.
- Whether the ratio changed without rebuilding the state object.

Interpreting the result
This result is Intel IPP status -29. AllStat describes it as “MR FIR sampling factor is less than, or equal to zero.”. The decisive context is the exact IPP routine and overload, because status names are shared across image, signal, codec, cryptography, and data-compression domains with different parameter contracts.
Developer checks
- Record the full function name, library version and CPU dispatch, source and destination types, ROI or vector length, step values, scale factor, and every state/specification object passed to the call.
- Validate the result parameter group before changing buffers: initialization routines often establish constraints inherited by later processing calls.
- use ippGetStatusString for logging but branch on the numeric IppStatus value; localized or wrapper text is not a stable program contract.
Retrying this result with unchanged arguments normally reproduces the same validation failure. Rebuild the affected IPP state when configuration changed, verify buffer bounds and alignment, and isolate the smallest call that still returns the status.
