On X11 you could place semi-<br> transparent window on top with your controls, but this is not possible<br> on wayland.<br> <br> In general best is to use a specific videosink for your application<br> widget system. For QT you could maybe try qmlglsink. It will use a GL<br> rendererer, and the display will be just like any other widget.<br> <span class="">><br> > Setup includes testing videosource which broadcasts over udp to<br> > udpsink.<br> ><br> > I am trying to do exactly that in Qt 5.8 on windows but when I start<br> > video widget gets overwritten.<br> > Are there any examples of this, especially because this seems pretty<br> > standard task to most things done with video playing.<br> ><br> ><br> > Kind regards,<br> > Nikola.<br> </span>> ______________________________<wbr>_________________<br> > gstreamer-devel mailing list<br> > <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.<wbr>freedesktop.org</a><br> > <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/<wbr>mailman/listinfo/gstreamer-<wbr>devel</a><br>______________________________<wbr>_________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.<wbr>freedesktop.org</a><br> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/<wbr>mailman/listinfo/gstreamer-<wbr>devel</a><br> <br></blockquote></div><br><br clear="all"><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature">God is Real, unless declared Integer. <br>J.
