ippStsAacPredSfbErr
This status is about AAC prediction metadata, not ordinary stereo prediction in a container. AAC Main and related tools can mark scalefactor bands for prediction, but those bands must be inside the profile-specific range.
Investigate the object type and the Individual Channel Stream header before blaming the output buffer. A Low Complexity stream should not require Main-profile prediction handling.
What matters
- The audio object type and profile negotiated for the decoder.
- The number of prediction bands available for the selected sampling rate.
- Whether the stream was mislabeled as a different AAC profile.
