VIDEOENCODER_BITRATE_MODE enumeration (strmif.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VIDEOENCODER_BITRATE_MODE enumeration type defines the three types of bitrates supported by the IEncoderAPI interface.
Syntax
typedef enum VIDEOENCODER_BITRATE_MODE {
ConstantBitRate = 0,
VariableBitRateAverage,
VariableBitRatePeak
} ;
Constants
ConstantBitRate Value: 0 The bit rate used for encoding is constant. |
VariableBitRateAverage The bit rate used for encoding is variable with the specified bitrate used as a guaranteed average over a specified window. The default window size is considered to be five minutes. |
VariableBitRatePeak The ENCAPIPARAM_BITRATE value is the expected (not guaranteed) average bit rate over a given time period and that the ENCAPIPARAM_PEAK_BITRATE value is the peak which the bit rate must not exceed. The default window size is considered to be 500ms (which is traditionally equal to one GOP). |
