ippStsH263BlockStepErr

Step is the distance in bytes between rows of a block buffer. For H.263 block operations it must be large enough for an 8-pixel block row.

This status indicates a memory-layout contract violation rather than compressed syntax corruption.

Check these details

  • The pointer and step passed for the current 8x8 block.
  • Whether cropped or edge blocks reuse a smaller pitch accidentally.
  • Alignment and plane stride after format conversion.
