5.27 Frame Rate
5.27.1 Detailed Description
The frame rate filter modifies the source frame rate either by applying a specific frame rate (e.g. 12.0) or a
decimation interval (e.g. 2 = 1/2 source frame rate).
Filter Parameters:
Name | Type | Opt/Reqd | Range
============================================================================
FE2_FRAMERATE_FPS | Numeric | Optional | [0.0,)
FE2_FRAMERATE_DECIMATE | Numeric | Optional | [1,)
Example Usage:
sc = Flix2_AddFilter(&filter, flix, FE2_FILTER_FRAMERATE);
// decimate by 2. ex. 29.97fps becomes 14.985
if(sc == ON2_OK)
sc = Flix2_FilterSetParam(filter, FE2_FRAMERATE_DECIMATE, 2);
