ippStsAacBitOffsetErr
AAC parsing is bit-oriented. This status means the decoder was asked to continue from an offset that is outside the current buffer, not byte-aligned where the API requires it, or inconsistent with fields already consumed.
It often appears after truncated packets, incorrect ADTS frame length, or wrapper code that reuses a bitstream state across frames without resetting it correctly.
Check
- The byte length of the compressed frame and the bit offset passed to IPP.
- Whether ADTS headers were stripped or included consistently.
- The offset after section, scalefactor, TNS, and spectral decoding.
