Streaming through NEWTEK NDI

Description

The NDI streaming requires the Newtek NDI runtime, and the optional Datastead NDI Filters package that can be downloaded here :

https://www.datastead.com/downloads/

The installation of the Datastead NDI filters and the Newtek NDI runtime are described in the INSTALL_README.rtf

Sample code to send a stream to the network:

Videograbber.VideoSource = ...

VideoGrabber.NDIName = "MYSTREAM";

Videograbber.NetworkStreaming = ns_NDI;

Videograbber.NetworkStreamingType = nst_VideoStreaming; // or nst_AudioVideoStreaming if audio needed

Videograbber.StartPreview();

E.g. if the video source is a Logitech 930e webcam:

Videograbber.VideoSource = vs_VideoCaptureDevice;

Videograbber.VideoDevice = Videograbber.VideoDeviceIndex ("Logitech Webcam C930e");

Videograbber.AudioDevice = Videograbber.AudioDeviceIndex ("Microphone (Logitech Webcam C930e)");

VideoGrabber.NDIName = "MYSTREAM";

Videograbber.NetworkStreaming = ns_NDI;

Videograbber.NetworkStreamingType = nst_AudioVideoStreaming;

Videograbber.StartPreview();

Sample code to play a stream from the network:

Videograbber.VideoSource = vs_VideoFileOrURL;

Videograbber.VideoSource_FileOrURL = "ndi://DESKTOP-5B66SBT (MYSTREAM)";

Videograbber.AudioDeviceRendering = true ;

Videograbber.StartPreview();

Notes:

- replace "DESKTOP-5B66SBT" by the name of the computer that is streaming to the network, and "MYSTREAM" by the real stream name to use.

- if the sender and receiver are on the same computer, the computer name can be replaced by "localhost", e.g.:

Videograbber.VideoSource_FileOrURL = "ndi://localhost (MYSTREAM)";
