ippStsDecimateFractionErr
Decimation and resampling paths combine a sample-rate ratio with filtering. IPP reports this status when the requested fractional ratio is not one supported by that routine.
Check the ratio representation rather than only the buffers. Some APIs require integer factors, reduced fractions or predefined polyphase setup.
Check these details
- Upsampling and downsampling factors after reducing the fraction.
- Whether the selected routine supports arbitrary or fixed-ratio resampling.
- The anti-aliasing filter configuration coupled to the same ratio.
