ippStsECCInvalidFlagErr ippStsMP3SideInfoErr

ippStsMP3FrameHeaderErr

This status belongs to MP3 bitstream parsing. The frame header carries the sync pattern, MPEG version, layer, bitrate index, sampling-rate index, padding and channel mode fields; inconsistent values prevent the decoder from deriving the frame layout.

It is different from a PCM output-buffer problem. The decoder cannot reliably locate or describe the compressed frame before sample reconstruction begins.
