ippStsMP4PredDirErr
Prediction direction controls how neighboring samples or motion-compensated references are used. An impossible direction usually means the macroblock mode or the surrounding prediction state is inconsistent.
For intra blocks, inspect DC/AC prediction state. For inter blocks, inspect motion-vector prediction and reference availability.
Check these details
- The macroblock mode and whether intra AC/DC prediction is active.
- Neighbor availability at picture or video-packet boundaries.
- Reference frame state if the failing block is inter-coded.
