ippStsH263ZigzagLenErr

Transform coefficients are scanned in zigzag order across an 8x8 block. A compact run that would exceed 64 coefficient positions is structurally impossible.

This status usually means a run-level code is corrupt or the decoder selected the wrong coefficient table.

Check these details

  • The run and level value that caused the scan position to exceed the block.
  • The coefficient table and intra/inter context.
  • Whether previous escape-code handling consumed the correct number of bits.
