* ## Example launch line
* |[
* gst-launch-1.0 udpsrc ! tsparse set-timestamp=1 ! rtpmp2pay ! ristsink address=10.0.0.1 port=5004
* gst-launch-1.0 udpsrc ! tsparse set-timestamp=1 ! rtpmp2pay ! \
* ristsink address=10.0.0.1 port=5004
* ]|
*
* Additionally, this element supports bonding, which concist of using multiple
* links in order to transmit the streams. The address of each bonds is
* configured through "bonding-addresses" property. When set, this will replace
* the value that might have been set on "address" and "port". Each bonds will be
* mapped to it's down RTP session. RTX request are only replied on the link
* the NACK was received from.
*
* ## Exmaple launch line for bonding
* |[
* gst-launch-1.0 udpsrc ! tsparse set-timestamp=1 ! rtpmp2pay ! \
* ristsink bonding-addresses="10.0.0.1:5004,11.0.0.1:5006"
