VT Publisher
VT Publisher is the app that is run on the sending side. It supports the following input options:
NDI;
SDI or HDMI sources via Blackmagic, AJA or Magewell;
Generic video devices, such as web cams (via DirectShow).
First, check that the current version of VT Publisher is the same or newer than the latest release version. If not, click the "Update" button to download the latest release.
Select the source you wish to publish from the list of available sources (5). Once selected, the preview of the source will start and it's parameters will be shown (6).
Copy the Publisher ID (4) and send it to the receiving side (to paste in VT Receiver). You can use the same Publisher ID on multiple instances of VT Publisher and VT Receiver.
You can set a custom name for this particular instance of VT Publisher via the "Location" field – to make it easier to locate this feed in VT Receiver.
To start publishing, choose the desired bitrate (7) and hit "Start Publishing" (11).
Once the stream has been started, the URL appears in the "URL" tab (8). One can open this URL in a browser to receive a high-quality WebRTC preview of this feed.
Here's what it looks like.
