ippStsAacSectErr
AAC section_data tells the decoder how runs of scalefactor bands are grouped and which band type each run uses. This status means the number or length of sections is inconsistent with the current max_sfb and window grouping.
Look for a bitstream that has been truncated inside the ICS, wrong short-window grouping, or an earlier sample-rate/profile mismatch that selected the wrong scalefactor-band table.
Diagnostics
- Recompute section lengths until they cover exactly the coded bands.
- Verify the window-group count before parsing section runs.
- Check the bit offset at the beginning and end of section_data.
