What does Intel IPP status -24 (ippStsDlyLineIndexErr) mean?

ippStsDlyLineIndexErr

Delay-line based filters and generators rely on a circular state history. This status means an index into that history is outside the state layout expected by the routine.

The important state is not the current input sample but the initialized delay buffer, its length and the current read/write index.

Check these details

• State initialization used before the processing call.
• The delay-line length compared with filter order.
• Whether the index was restored from stale serialized state.
