MF_TOPOLOGY_TYPE enumeration (mfidl.h)

  • Article

Defines the type of a topology node.

Syntax

typedef enum MF_TOPOLOGY_TYPE {
  MF_TOPOLOGY_OUTPUT_NODE = 0,
  MF_TOPOLOGY_SOURCESTREAM_NODE,
  MF_TOPOLOGY_TRANSFORM_NODE,
  MF_TOPOLOGY_TEE_NODE,
  MF_TOPOLOGY_MAX = 0xffffffff
} ;

Constants

 
MF_TOPOLOGY_OUTPUT_NODE
Value: 0
Output node. Represents a media sink in the topology.
MF_TOPOLOGY_SOURCESTREAM_NODE
Source node. Represents a media stream in the topology.
MF_TOPOLOGY_TRANSFORM_NODE
Transform node. Represents a Media Foundation Transform (MFT) in the topology.
MF_TOPOLOGY_TEE_NODE
Tee node. A tee node does not hold a pointer to an object. Instead, it represents a fork in the stream. A tee node has one input and multiple outputs, and samples from the upstream node are delivered to all of the downstream nodes.
MF_TOPOLOGY_MAX
Value: 0xffffffff
Reserved.
