Enumeration Type Documentation

MapMode

enum class QtVideo::MapMode

strong

Enumerates how a video buffer's data is mapped to system memory.

\value NotMapped The video buffer is not mapped to memory. \value ReadOnly The mapped memory is populated with data from the video buffer when mapped, but the content of the mapped memory may be discarded when unmapped. \value WriteOnly The mapped memory is uninitialized when mapped, but the possibly modified content will be used to populate the video buffer when unmapped. \value ReadWrite The mapped memory is populated with data from the video buffer, and the video buffer is repopulated with the content of the mapped memory when it is unmapped.

Rotation

enum class QtVideo::Rotation

strong

Since

6.7

The angle of the clockwise rotation that should be applied to a video frame before displaying.

\value None No rotation required, the frame has correct orientation \value Clockwise90 The frame should be rotated clockwise by 90 degrees \value Clockwise180 The frame should be rotated clockwise by 180 degrees \value Clockwise270 The frame should be rotated clockwise by 270 degrees
