ippStsAacWinSeqErr
The AAC Individual Channel Stream uses a small window_sequence enumeration: long, long-start, eight-short, and long-stop. This status means the bitstream selected a value outside the decoder's valid set.
Because window sequence determines grouping, TNS limits, prediction, and transform length, this error can cascade into many later failures if ignored.
Check first
- The bit offset at the start of the ICS header.
- The object type and common_window state for channel pairs.
- Whether a damaged previous field shifted the parser by one bit.
