OBS Link is a small program that lives in the menu bar of your Mac. It grabs the incoming video from your Elgato Game Capture HD60 S and converts it to NDI. The NDI signal can then be captured in OBS Studio using the NDI plugin. Latency of the game going to OBS Studio via OBS Link is around ~250ms. This will vary with your system and setup.
OBS Link requires macOS Mojave 10.14 or later.
Lets go over how to setup OBS Link:
1) Download and install OBS Link 1.0.
3) Connect your Elgato Game Capture HD60 S device to your Mac.
4) Click on the OBS Link menu bar icon and select the HD60 S.
Open the Preferences to change settings such as HDMI or analog audio input, HDMI color range, resolution and more.
5) Open OBS Studio and add a new NDI Source.
if you have OBS open at the time you install the NDI plugin, you will have to restart OBS for the "NDI Source" option to become available.
6) Give the source a name such as "HD60 S" or "OBS Link".
7) In the NDI source settings window, from the source name menu, select the OBS Link source.
It will have (OBS Link) at the end with the name of your computer and .local in it as seen in the screenshot.
8) Click on OK, and after a few moments video from the HD60 S will appear in OBS Studio.
