The</div><div>sink will query this and then knows that it might take that much time</div><div>for the frame to be captured and make its way through the pipeline.</div><div><br></div><div>2) at the sink: you can create an eglglessink yourself and set it on</div><div>playbin via the video-sink property. Sinks have a 'max-lateness'</div><div>property, which determines how late buffers have to be before they will</div><div>be dropped. So you can tweak that or even unset it (not recommended, and</div><div>shouldn't be necessary) to allow for more lateness. The default for this</div><div>is 20ms.</div><div><br></div><div>You can also set the "sync" property on the sink to FALSE, but I would</div><div>not recommend it, then the sink will not look at the timestamps at all</div><div>any more and you may get very jittery video.</div><div><br></div><div> Cheers</div><div> -Tim</div><div><br></div><div>-- </div><div>Tim Müller, Centricular Ltd - <a href="http://www.centricular.com">http://www.centricular.com</a></div><div><br></div><div>_______________________________________________</div><div>gstreamer-android mailing list</div><div><a href="mailto:gstreamer-android@lists.freedesktop.org">gstreamer-android@lists.freedesktop.org</a></div><div><a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-android">http://lists.freedesktop.org/mailman/listinfo/gstreamer-android</a></div></div></div></span>
