MF_SA_D3D11_BINDFLAGS attribute

Specifies the binding flags to use when allocating Microsoft Direct3D 11 surfaces for media samples.

Data type



The value of this attribute is a bitwise OR of D3D11_BIND_FLAG flags.

Microsoft Media Foundation Transforms

In this context, the attribute applies only when the Microsoft Media Foundation transform (MFT) returns TRUE for the MF_SA_D3D11_AWARE attribute.

If an MFT supports Direct3D 11, this attribute provides a hint to the MFT when allocating Microsoft Direct3D surfaces for output. Set the attribute as follows:

  1. Call IMFTransform::GetOutputStreamAttributes to get the MFT attribute store.
  2. Call IMFAttributes::SetUINT32.

The Media Foundation pipeline sets the attribute before streaming starts. The MFT should attempt to honor the setting when it allocates surfaces. If that is not possible, the MFT can ignore the attribute, rather than failing the allocation.

In addition, if the MFT requires Direct3D surfaces for input, it can expose this attribute as a hint for how the input surfaces should be allocated. Query the attribute as follows:

  1. Call IMFTransform::GetInputStreamAttributes to get the input stream attributes.
  2. Call IMFAttributes::GetUINT32.

Sample Allocator

This attribute can be set on the video sample allocator, in the IMFVideoSampleAllocatorEx::InitializeSampleAllocatorEx method.
