Enumeration Type Documentation

enum NvOSD_Mode

List modes used to overlay boxes and text.

Enumerator
MODE_CPU	Selects CPU for OSD processing. Works with RGBA data only
MODE_GPU	Selects GPU for OSD processing. Yet to be implemented
MODE_HW	Selects NV HW engine for rectangle draw and mask. This mode works with both YUV and RGB data. It does not consider alpha parameter. Not applicable for drawing text.
