ippStsH263MBStepErr

A macroblock covers a 16-pixel luma span, so the row step for macroblock operations must not be smaller than that requirement. IPP reports this before doing prediction or transform work.

Fix the frame-plane pitch or the wrapper calculation; changing the encoded bitstream will not address this status.

Check these details

  • Luma and chroma plane stride values.
  • Whether the buffer describes a full frame, a slice, or a cropped region.
  • Sub-buffer offsets used at picture edges.
