ippStsH263DCCodeErr
Intra blocks carry DC information as part of coefficient decoding. This status means the DC code could not be interpreted for the current block.
The error is before inverse transform. Inspect the compressed coefficient stream, not the reconstructed image output.
Check these details for ippStsH263DCCodeErr
- Whether the macroblock is intra-coded.
- The block index inside the macroblock.
- The coefficient reader state before the DC field.

Interpreting the result
This result is Intel IPP status -73. AllStat describes it as “Illegal code is detected during DC stream processing.”. 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.
