IMFSpatialAudioObjectBuffer interface (mfspatialaudio.h)
Represents a section of audio data with associated positional and rendering metadata. Spatial audio objects are stored in IMFSpatialAudioSample instances, and allow passing of spatial audio information between Media Foundation components.
Inheritance
The IMFSpatialAudioObjectBuffer interface inherits from IMFMediaBuffer. IMFSpatialAudioObjectBuffer also has these types of members:
Methods
The IMFSpatialAudioObjectBuffer interface has these methods.
| IMFSpatialAudioObjectBuffer::GetID Returns the unique, unsigned 32-bit ID of the spatial audio object represented by the buffer. |
| IMFSpatialAudioObjectBuffer::GetMetadataItems Retrieves a pointer to a buffer that may contain spatial audio metadata. |
| IMFSpatialAudioObjectBuffer::GetType Gets the type of the spatial audio object represented by the buffer. If SetType has not been called previously, this method returns the default value of AudioObjectType_None. |
| IMFSpatialAudioObjectBuffer::SetID Sets the ID of the spatial audio object represented by the buffer. |
| IMFSpatialAudioObjectBuffer::SetType Sets the type of the spatial audio object represented by the buffer. |
Remarks
To get the audio data contained in the spatial audio object, use the IMFMediaBuffer::Lock and IMFMediaBuffer::Unlock methods.
