KSDEVICE_PROFILE_INFO structure (ksmedia.h)

  • Artikel

The KSDEVICE_PROFILE_INFO is a generic structure designed to handle profile information for various device types.

Syntax

typedef struct _KSDEVICE_PROFILE_INFO {
  UINT32 Type;
  UINT32 Size;
  union {
    struct {
      KSCAMERA_PROFILE_INFO             Info;
      UINT32                            Reserved;
      UINT32                            ConcurrencyCount;
      PKSCAMERA_PROFILE_CONCURRENCYINFO Concurrency;
    } Camera;
  };
} KSDEVICE_PROFILE_INFO, *PKSDEVICE_PROFILE_INFO;

Members

Type

Defines the type of profile. Currently, the only defined type is KSDEVICE_PROFILE_TYPE_CAMERA.

#define KSDEVICE_PROFILE_TYPE_CAMERA    0x00000001

Size

This must be set to sizeof(KSDEVICE_PROFILE_INFO) structure.

Camera

Camera.Info

Structure of KSCAMERA_PROFILE_INFO defining the profile information of a camera.

Camera.Reserved

Unused. Must be set to 0.

Camera.ConcurrencyCount

Number of KSCAMERA_PROFILE_CONCURRENCYINFO structures in the Concurrency array.

For Windows 10 this must be less than or equal 1.

A value of 0 with Concurrency set to NULL, indicates this profile is non-concurrent.

Camera.Concurrency

An array of KSCAMERA_PROFILE_CONCURRENCYINFO structures describing the concurrency support for this profile.

If CountOfConcurrency is 0, this parameter must be NULL.

If CountOfConcurrency is greater than 0, this parameter must not be NULL.
