MP_ENVELOPE_SEGMENT structure (medparam.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The MP_ENVELOPE_SEGMENT
structure defines an envelope segment used by an envelope-following parameter.
Syntax
typedef struct _MP_ENVELOPE_SEGMENT {
REFERENCE_TIME rtStart;
REFERENCE_TIME rtEnd;
MP_DATA valStart;
MP_DATA valEnd;
MP_CURVE_TYPE iCurve;
MP_FLAGS flags;
} MP_ENVELOPE_SEGMENT;
Members
rtStart
Start time of the segment, relative to the time stamp on the first buffer, in 100-nanosecond units.
rtEnd
Stop time of the segment, relative to the time stamp on the first buffer, in 100-nanosecond units.
valStart
Initial value of the parameter, at the start of the segment.
valEnd
Final value of the parameter, at the end of the segment.
iCurve
Member of the MP_CURVE_TYPE enumerated type that specifies the curve followed by the parameter.
flags
Specifies one of the following flags.
Value | Meaning |
