ok, i have tried to use GstNetTimeProvider and GstNetClientClock with this code:<div><br><div>//on the server side</div><div>gst_element_set_state (pipeline, GST_STATE_PLAYING);<br><div>GstClock * clock = (GstClock *)gst_pipeline_get_clock((GstPipeline*)pipeline);</div>
<div>gst_net_time_provider_new(clock, "127.0.0.1", 3333);</div><div><br></div><div>//on the client side</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">GstClock * netclientclock = gst_net_client_clock_new("net_clock", "127.0.0.1", 3333, GST_SECOND);</div>
<div><div>gst_pipeline_use_clock((GstPipeline*)pipeline, netclientclock);</div></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8">gst_element_set_state (pipeline, GST_STATE_PLAYING);</div><div>
<br>
</div><div>results:</div><div>the two pipelines are not synchronized but if I calibrate the server clock to a double speed the client goes at double speed:</div><div>gst_clock_set_calibration(clock, (GstClockTime)0, gst_clock_get_time(clock), (GstClockTime)2, ( GstClockTime)2);</div>
<div><br></div><div>so i think that the two clocks are synchronized, now my question is: how can i set the same start time on the two pipelines? </div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>

You can setup a multicast pipeline to play out the video source and have each receiving pc have the rx end running continually so that when you start the playing from the server it will start the decode on each receiving pc. <br>

Hi all, <br>i'm a newbie gstreamer developer, i'm trying to build two pipelines for play a video in two different computers that will play in frame sync. what is the best way to do this? <br>(each computer have the source video file in the local filesystem)</div>
