MFT_CONNECTED_TO_HW_STREAM attribute
Specifies whether a hardware-based Media Foundation transform (MFT) is connected to another hardware-based MFT.
Data type
UINT32
Get/set
To get this attribute, call IMFAttributes::GetUINT32.
To set this attribute, call IMFAttributes::SetUINT32.
Remarks
Applications typically do not use this attribute.
This attribute is used with hardware-based MFTs. When two hardware MFTs are connected within a topology, the topology loader sets this attribute to TRUE on the following objects:
- The output stream of the upstream MFT
- The input stream of the downstream MFT
To get the attribute store for the output stream, the topology loader calls IMFTransform::GetOutputStreamAttributes on the upstream MFT. To get the attribute store for the input stream, the topology loader calls IMFTransform::GetInputStreamAttributes on the downstream MFT.
The GUID constant for this attribute is exported from mfuuid.lib.
