I read <a class="moz-txt-link-freetext" href="http://gstreamer-devel.966125.n4.nabble.com/Synchronization-of-multiple-senders-using-rtpBin-td4674390.html">http://gstreamer-devel.966125.n4.nabble.com/Synchronization-of-multiple-senders-using-rtpBin-td4674390.html</a> and implemented this to sync the receiver and the sender. But is it achievable to convert the splitmuxsink running time to the (NTP) time of capture on the sender ?

On the receiver the video is saved in files of 10 seconds using splitmuxsink. This works fine ! Now we want to save the start and stop time of each individual video file. I can 'capture' the "splitmuxsink-fragment-opened" and "splitmuxsink- fragment-opened" messages from splitmuxsink and read the running time. It seems the running time is a time in nanosecond since the stream started. How can i convert that time to the absolute time the stream was captured ? </pre> </blockquote> <pre wrap=""> See gstreamer/docs/design/part-synchronisation.txt for details, but the clock time corresponding to a running time can be calculated with clock_time = running_time - base_time where base_time is the return value of gst_element_get_base_time(). Note that this only gives you a time corresponding to the pipeline's clock. Which is not necessarily the same as the wall clock. If you want to have the wall clock time, you could force a system clock on the pipeline before starting (gst_pipeline_use_clock()) and set its clock-type property to GST_CLOCK_TYPE_REALTIME. </pre> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> <div class="moz-signature">-- Rini van Zetten Senior Software Engineer ------------------------- ARVOO Engineering B.V.
