IMediaPosition::put_Rate (Windows Embedded CE 6.0)
1/6/2010
This method sets the rate of playback relative to normal speed.
Syntax
HRESULT put_Rate(
double dRate
);
Parameters
- dRate
[in] Rate to set.
Return Value
Returns an HRESULT value.
Remarks
This method allows an application to speed up or slow down playback relative to the normal default playback speed. A rate of 1.0 indicates normal playback speed. Specifying 2.0 causes playback at twice the normal rate: a video created for 10 frames per second (fps) will be played back at 20 fps, if resources permit. Audio streams played back at above-normal speed increase the pitch rather than drop samples.
