1. vMix receives the SRT stream pushed by the encoder in Listener mode.
1. Open the vMix software, click "Add Input"-"More" in the lower left corner, and select the "Stream/SRT" option. The interface is as shown below.
2. Select "Stream Type" is "SRT (Listener)", configure "Port", "Latency", "Passphrase" (if necessary), "Decoder Delay" and other parameters in turn, and click "OK" to complete the configuration.
3. In the main interface of vmix, you can see that vmix has been monitoring the SRT stream in the Input1 window, and the window is displayed as a black screen when there is no video stream input.
4. Configure the Qianshi encoder as a Caller to initiate an SRT connection, and configure the "handshake mode", "IP address", "port", "transmission delay" and other parameters in turn (relevant parameters need to correspond to the vmix side)
5. SRT is correctly connected After that, vmix can normally receive and display the video images transmitted by the encoder.
2. vMix pushes the SRT stream to the decoder in Caller mode
1. Click the gear-shaped button on the left of "External" at the bottom and select "Output/NDI/SRT Settings"
2. Pop up the Settings menu and select the "Outputs/NDI/SRT" option. The source of "Output" selects the video source that needs to be transmitted (if Input1 is selected, ensure that Input1 has a video signal). Click the gear-shaped setting button to pop up the "Output Settings" dialog box, check "Enable SRT", select "Type"
Configure the corresponding parameters for "Caller", "Hostname", "Port", "Latency", "Passphrase" and "Quality" in turn, check "Use Hardware Encoder", and click "OK" to confirm. ( "Use Hardware Encoder" generally need to choose, can improve coding ability)
3, in the one thousand-view video decoder, adding an SRT type video source to receive SRT flow, sequentially for "name", "handshake mode 
Mode" "The Listener" , "Port Number" and "Transmission Delay" and other parameters are consistent with the vmix configuration.
4. Check whether the SRT handshake connection is normal and whether there is video image output in the decoder. If not, you can click the "SRT"-"Enable" option on the gear-shaped button on the left side of "External", and reconfigure to turn off and then turn on the vmix push (Enable represents the push state).
