There is currently no API to the tracers, this is something we should do, we we already have few bits marked as unstable API because their API isn't yet in a shape we are confident to freeze it. >From the time being, you need to set the env before starting the process or do this before calling Gst.init(): os.environ["GST_TRACERS"] = "latency(flags=element)" There is no way to turn on and off at run-time for now. > > Thank you in advance. > > Michael > > > _______________________________________________ > gstreamer-devel mailing list > <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> > <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
