Synchronization of multiple senders using rtpBin

[danny.smith]

Hi,

I am using a similar scenario where we have synchronized senders
transmitting audio from a microphone to one receiver.
Have followed the above description and we are using net-time-provider and
net-client-clock to provide the synchronization.

We have the net-time-provider on one unit and the senders/receivers
net-client-clock synchronize against this provider.
This works well if the unit which runs the time-provider has been started
before the sender units, i.e. the time-provider units uptime is larger than
the sender units. If it works, the function call to gst_clock_id_wait() in
gst_base_sink_wait_clock() in gstbasesink.c returns GST_CLOCK_EARLY (this is
through the sender udpsink). If it does not work, we hang in the same
function call. Have tried setting sync=false which should disable this check
but the setting does not seem to be respected.

Using Gstreamer 1.10.4. Have we missed something? Have tried experimenting
with a lot of settings but have failed to solve this issue.

Thankful for any insights!

Regards,
Danny
