MFNETSOURCE_STATISTICS_IDS enumeration
Defines statistics collected by the network source. The values in this enumeration define property identifiers (PIDs) for the MFNETSOURCE_STATISTICS property.
To retrieve statistics from the network source, call IMFGetService::GetService with the service identifier MFNETSOURCE_STATISTICS_SERVICE and the interface identifier IID_IPropertyStore. The retrieved pointer is an IPropertyStore pointer. To get the value of a network statistic, construct a PROPERTYKEY with fmtid equal to MFNETSOURCE_STATISTICS and pid equal to a value from this enumeration. Then call IPropertyStore::GetValue with the property key to retrieve the value of the statistic as a PROPVARIANT.
In the descriptions that follow, the data type and value-type tag for the PROPVARIANT are listed in parentheses.
