ippStsContextMatchErr
Many IPP APIs use initialized context objects for filters, codecs, cryptography, transforms or statistics. This status means the context exists, but it was not initialized for the primitive or mode being invoked.
It commonly appears after reusing a context across incompatible algorithms, changing parameters without reinitialization, or mixing contexts from different IPP domains.
Diagnostic focus
- Record the function that initialized the context and the function that later failed.
- Check context size/version, algorithm mode, precision, channel count and initialization parameters.
- Do not reinterpret an opaque IPP context between primitive families.
