CAPTURE_MEMORY_ALLOCATION_FLAGS enumeration (ksmedia.h)

  • Article

The CAPTURE_MEMORY_ALLOCATION_FLAGS enumeration defines types of memory surfaces to which AVStream minidrivers can capture audio and video data. The KSPROPERTY_PREFERRED_CAPTURE_SURFACE and KSPROPERTY_CURRENT_CAPTURE_SURFACE requests use this type to specify property values.

Syntax

typedef enum {
  KS_CAPTURE_ALLOC_INVALID,
  KS_CAPTURE_ALLOC_SYSTEM,
  KS_CAPTURE_ALLOC_VRAM,
  KS_CAPTURE_ALLOC_SYSTEM_AGP,
  KS_CAPTURE_ALLOC_VRAM_MAPPED,
  KS_CAPTURE_ALLOC_SECURE_BUFFER
} CAPTURE_MEMORY_ALLOCATION_FLAGS, *PCAPTURE_MEMORY_ALLOCATION_FLAGS;

Constants
