Detailed Description

The QAbstractVideoBuffer::MapData structure describes the mapped plane layout.

\inmodule QtMultimedia

The structure contains a number of mapped planes, and plane data for each plane, specificly, a number of bytes per line, a data pointer, and a data size. The structure doesn't hold any ownership of the data it refers to.

A defaultly created structure means that no data has been mapped.

All the values in the structure default to zeros.
