ippStsAacTnsProfileErr
TNS support depends on the AAC object type and the exact syntax path selected by the decoder. This status means the stream requests TNS in a profile or mode where the IPP decoder path cannot accept it.
Confirm the AudioSpecificConfig rather than only the file extension. Two files named AAC can still select different object types and tool sets.
Useful checks
- The MPEG-4 Audio Object Type.
- Whether the decoder was initialized for AAC-LC, Main, SSR, scalable, or ER AAC.
- Whether a container-level profile contradicts the in-band bitstream.
