medparam.h contains the following programming interfaces:
Interfaces
| IMediaParamInfo The IMediaParamInfo interface retrieves information about the parameters that an object supports. The set of parameters that an object supports will not change over the lifetime of an application. To set parameter values, use the IMediaParams interface. |
| IMediaParams The IMediaParams interface sets and retrieves envelope-following parameters on an object. |
Structures
| MP_ENVELOPE_SEGMENT The MP_ENVELOPE_SEGMENT structure defines an envelope segment used by an envelope-following parameter. |
| MP_PARAMINFO The MP_PARAMINFO structure contains information about a parameter. |
Enumerations
| MP_CURVE_TYPE The MP_CURVE_TYPE enumeration defines the curve that a media parameter follows within an envelope segment. |
| MP_TYPE The MP_TYPE enumeration specifies the data type for a parameter. |
