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.
