MF_SD_ASF_EXTSTRMPROP_AVG_DATA_BITRATE attribute

Specifies the average data bit rate, in bits per second, of 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 Data Bit Rate field in the Extended Stream Properties object, and defines the leak rate 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.
