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.

MFNETSOURCE_AVGBANDWIDTHBPS_ID The average bandwidth of the clip (LONG, VT_I4). |
MFNETSOURCE_BYTESRECEIVED_ID The total number of bytes received (ULONGLONG, VT_UI8). |
MFNETSOURCE_PROTOCOL_ID The type of control protocol used to receive the data (LONG, VT_I4). The value is a member of the MFNETSOURCE_PROTOCOL_TYPE enumeration. |
MFNETSOURCE_TRANSPORT_ID The type of control protocol used to receive the data (LONG, VT_I4). The value is a member of the MFNETSOURCE_TRANSPORT_TYPE enumeration. |

MFNETSOURCE_SIGNEDSESSION_ID Boolean value indicating whether the current session is signed (VARIANT_BOOL, VT_BOOL). |
MFNETSOURCE_MAXBITRATE_ID The current maximum bit rate of the content (LONG, VT_I4). |
MFNETSOURCE_RECEPTION_QUALITY_ID The reception quality (LONG, VT_I4). |
MFNETSOURCE_RECOVEREDPACKETS_ID The total number of recovered packets (LONG, VT_I4). |
MFNETSOURCE_VBR_ID Boolean value indicating whether the content has a variable bit rate (VARIANT_BOOL, VT_BOOL). |
MFNETSOURCE_DOWNLOADPROGRESS_ID The percentage of the content that has been downloaded. The value is an integer in the range 0–100. (LONG, VT_I4). |
