ippStsH263PlaneStepErr

Plane step is the stride for an image plane. It must be at least the plane width for the active format; otherwise row access would overlap or leave the plane bounds.

This often happens when chroma and luma strides are mixed, or when a wrapper passes width in pixels where bytes are required.

Check these details

  • Luma versus chroma stride values.
  • Pixel size and subsampling assumptions.
  • Plane offsets for cropped frames.
