ippStsMP4ZeroBABErr
BAB means binary alpha block in MPEG-4 shape coding. This status belongs to shape-plane processing, not ordinary luma/chroma texture decoding.
All-zero alpha information can be legal in some high-level object decisions, but an IPP primitive may reject it when the current operation expects coded shape content for the block.
Check these details
- Whether the Visual Object uses binary alpha shape coding.
- The shape mode selected for the current macroblock.
- Whether the caller should skip transparent blocks instead of decoding them as coded BAB data.
