I am streaming live with a recorded video trailer at the end . Live stream is perfect but video trailer is out of sync. The video lags it seems a second or so. Original video is in sync. Is there setting I need to change in media source? Log files of test below.

Still lags with update. Trying offset in audio, doing minus. May be my imagination that that is helping but not right on. Any other suggestions out there?

Ok, Is there any reason when I upload a video to YouTube, audio and video is in sync. When adding a video to live stream, video lags a second or so?
