Remarks
The attribute is optional. Some formats have more complex encoding schemes that cannot be summarized by using this attribute. For Advanced Systems Format (ASF) files, the following attributes collectively describe the encoding bit rate:
- MF_PD_ASF_FILEPROPERTIES_MAX_BITRATE
- MF_SD_ASF_EXTSTRMPROP_AVG_DATA_BITRATE
- MF_SD_ASF_EXTSTRMPROP_MAX_DATA_BITRATE
- MF_SD_ASF_STREAMBITRATES_BITRATE
Third-party formats might use other custom attributes.
The GUID constant for this attribute is exported from mfuuid.lib.
