The new property allows to select the time source that should be used for the NTP time in RTCP packets. By default it will continue to calculate the NTP timestamp (1900 epoch) based on the realtime clock. Alternatively it can use the UNIX timestamp (1970 epoch), the pipeline's running time or the pipeline's clock time. The latter is especially useful for synchronizing multiple receivers if all of them share the same clock. If use-pipeline-clock is set to TRUE, it will override the ntp-time-source setting and continue to use the running time plus 70 years. This is only kept for backwards compatibility.
