How does vMix software pull NDI and output NDI stream?

NDI (Network Device Interface) is a network device interface. It is a copyright-free standard developed by the United States NewTek Company. It enables compatible video products to communicate, transmit and receive broadcast quality in a high-quality, low-latency, and frame-accurate manner. Video is very suitable for switching in a live production environment. In this document, Qianshi will introduce how to use VMIX to output content and receive NDI video streams on the local network through NDI.
1. VMIX pulls the NDI stream.
Open the VMIX software and click "Add Input" in the lower left corner to display various sources that can be added. Click the "NDI/Desktop Capture" option to display a
list of NDI devices , based on the device name and channel name , You can select the device you want to add and click "OK" to add the encoder video source to the VMIX playback source list.
Note: If the front-end NDI source is NDI|HX, you need to download and install the NDI|HX driver on the NEWTEK official website.

We see that the video stream of KILOVIEW N20 is found in the discovery list. Select this stream and click "OK" to add it to VMIX.

2. VMIX output NDI stream
Click the setting button pointed by the arrow below the software, and in the pop-up dialog box, select "Output/NDI" to enter the setting interface.

After entering the setting interface, select "Output/NDI/SRT", you can see "1-Output" on the right. Displaying "NDI ON" means that the NDI output has been turned on, and the source to be output can be selected in the drop-down option box.

Note: More advanced versions of VMIX can be set to output multiple NDI streams. The output resolution and frame rate can be selected in the menu "Display".

You can see the stream output by VMIX on the decoding page of Qianshi N20, click to decode the output.
