I can do the same for a videosink, and this means that the display will be built/initialized only when it has some data to handle: however, building/initializing the display takes some time (about 40ms for a 640x480 RGB video), and this introduces unwanted latency. </span></div><div id="yui_3_16_0_ym19_1_1500394570166_2426" dir="ltr"><span style="background-color: initial; font-family: Consolas, Monaco, "Andale Mono", "Ubuntu Mono", monospace; font-size: inherit; white-space:pre-wrap; word-spacing: normal;" id="yui_3_16_0_ym19_1_1500394570166_2720">Therefore I ask: Is there a way to avoid that latency and build a "blank" display (with a known size), in a dynamic pipeline, BEFORE the callback is called?</span></div></div></body></html>
