3) Fill in the pushing address and port, click “ Save ” . Then SRT pushing is working.
Handshake mode: Caller 、 Listener 、 Rendezvous;
Address: Set IP address of the receiving port;
Port: Set the listening port corresponding to the receiving port;
Transport delay: Set it based on the performance of the current network, the delay value can be set on
both the SRT source device and the SRT target device. The final SRT transmission delay will be the larger
one of the two values. Default is 125ms;
Advanced settings: Open and Close;
Encryption mode: AES-128, AES-192, AES-256;
AES key: encryption AES key can be 10-32 letters or numbers combination;
Bandwidth overhead: It is set as the percentage value based on network link quality. Using this value to
multiply the total bitrate of the audio and video encoded by the encoder, this will get the occupied
maximum bandwidth allowed by Bandwidth Overhead. This value plus the total of video and audio
bitrate is the threshold of the current SRT transmission bandwidth, and also the maximum bandwidth
that SRT stream can be used. From the perspective of "overhead", it is the extra "invalid" bandwidth to
be used in addition to the media content required for transmission (which can be understood as the
payload), but it is different from our common protocol overhead, TCP header overhead, UDP header
overhead. The bandwidth overhead here is not a fixed 20~60 bytes TCP header overhead or 8 bytes UDP
header overhead. It changes in real time according to the network conditions. The worse the network
link conditions are, the more overhead needs for normal transmission. The range is 5%~100%, and the
default overhead is 25%;
Load size: Sending data packet size, it is optimal that the receiving port should equip with the same size.
The default size is 1316, the optimal packet for the codec.
