DirectShow IVideoFrameStep missing EC_STEP_COMPLETE |
| Manu30 posted 2009 Aug 25 14:32 |
| When i use IVideoFrameStep.step from a slow user interface interface (like clik on a button) my GetEvent loop receive the EC_PAUSED and then EC_STEP_COMPLETE as explain in the documentation. BUT, when i use a more rapid user interface (like draging a cursor with the mouse) then i still receive EC_PAUSED for each step but sometime EC_STEP_COMPLETE is missing.
Could somebody explain me the reason. Thank in advance. |
