3.4 Relay
▼Forward the streaming decoded by the decoder to RTMP/RTMPS or UPD/RTP protocols.
When the Local output is enabled，the HDMI/CVBS/VGA/SDI output of the decoder is normal
When the Local output is disabled，the HDMI/CVBS/VGA/SDI output of the decoder doesn’t work; The user
needs to disable this function when the stream decoded by the decoder exceeds 4 channels of 1080P,
otherwise the streaming address will not be able to decode.
When the user needs to forward the stream to the other RTMP server or platform, pls choose the” RTMP(S)”
model. At this point, the user only needs to enter the RTMP server and key/stream name in the "Addr1" and
"name" input boxes.

E.g.
The user's RTMP server address is rtmp://a.rtmp.youtube.com/live2
The stream Key is 7thy-519k-6yux-cubs-xxxx
At the same time, you can get a forwarded RTMP address on the status page (As shown below)
When the user wants to forward the streaming to UDP or RTP protocol, pls choose the” others” model. At this
point, The user fills in the UDP or RTP address in the input box of Url1
E.g:
udp://@232.0.0.1:1234
rtp://@232.0.0.1:1234
