Grabber::getGraphStartReferenceTime Method |
||||||||||||||
| This method retrieves the reference time at which the image stream (the filter graph) was started. | ||||||||||||||
| Syntax: | bool getGraphStartReferenceTime(REFERENCE_TIME& GraphStart) const; |
|||||||||||||
|
||||||||||||||
| Return value: | true on success, false otherwise. |
|||||||||||||
| Remarks: | The returned value in GraphStart specifies the time in 100 nanosecond (or 1/10000 millisecond) resolution. The resolution depends on the reference clock used internally by DirectShow (but it is mostly equivalent to QueryPerformanceCounter). If no reference clock is available, this method fails. |
