MF_MT_SPATIAL_AUDIO_OBJECT_METADATA_FORMAT_ID attribute

A decoder-defined GUID that identifies the spatial audio metadata format, notifying downstream components of the metadata object type that the decoder will output.

Data type

GUID

Remarks

The metadata blob with the specified format is written using the ISpatialAudioMetadataWriter interface and read using the ISpatialAudioMetadataReader interface. The metadata blob is opaque to the Media Foundation pipeline and components. The attribute is applied to the spatial audio media type. If a downstream component does not support the metadata format specified by the GUID, the component should reject the input media type.
