MF_SESSION_QUALITY_MANAGER attribute

Contains the CLSID of a quality manager for the Media Session.

Data type

GUID

Remarks

You can use this attribute to provide a custom quality manager for the Media Session.

Set this attribute by using the pConfiguration parameter of the MFCreateMediaSession or MFCreatePMPMediaSession function.

If this attribute is set, the Media Session calls CoCreateInstance with the specified CLSID to create the quality manager. The object created by this CLSID must expose the IMFQualityManager interface.

If this attribute is not set, the Media Session creates the default quality manager provided in Media Foundation.

If you want to run the Media Session with no quality manager at all, set this attribute to GUID_NULL.

The GUID constant for this attribute is exported from mfuuid.lib.
