MF_SD_ASF_EXTSTRMPROP_AVG_BUFFERSIZE attribute
Specifies the average buffer size, in bytes, needed for a stream in an Advanced Systems Format (ASF) file.
Data type
UINT32
Remarks
This attribute applies to stream descriptors for ASF content. It corresponds to the Buffer Size field in the Extended Stream Properties object, and defines the bucket size used in the "leaky bucket" model. For more information, refer to the ASF specification.
The IMFASFContentInfo::GeneratePresentationDescriptor method generates this attribute from the ASF metadata. The application can create the stream descriptor for the stream from the presentation descriptor by calling IMFPresentationDescriptor::GetStreamDescriptorByIndex.
