amfIMovie SetSpeedupTracking
Sets the value by which the video resolution will be divided in order to speed up tracking.
Syntax
movie_handle SetSpeedupTracking divisor
Description
Sets the value by which the video resolution will be divided before calculating the tracking data, in order to speed up marker tracking.
Inputs
- divisor
- The default value is 1, which will result in no speedup. A value of 2 will yield the greatest speedup benefit with the safest results. A value which is too high will result in inaccurate tracking results, and higher values yield only marginally better speed. This value will be used by the amfIMovie::CalculateTrackingData API, unless otherwise specified.
Example
movie_handle SetSpeedupTracking 2
Error
- 1 = HW_Error
- 3 = HW_InvalidHandle
- 4 = HW_InvalidArgs
