You don't even need to have a timer, the sink will wait until the right time is reached.</div><div><br></div><div>Olivier</div><div><br></div><div>On Tue, 2021-02-02 at 13:20 -0600, Trey Hutcheson wrote:</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div dir="ltr">I have two video files that were created by a single pipeline; they were started approximately 5 seconds apart.
