How Preroll EVR using Activate Objects RRS feed

  • Question

  • I gather from the performance of video playback that EVR doesn't actually preroll by default. I also found the NotifyPreroll method in the documentation, but that would require access to the MediaSink. Unfortunately we are using Activate objects to instantiate EVR and I can't seem to find a way to notify EVR to preroll. Is it possible to tell EVR to preroll when using activate objects?

  • The media session automatically prerolls sinks that support preroll before starting the presentation clock.  Typically, the EVR will preroll two frames before signalling preroll completion.  What performance issues are you seeing?
