If you fail to select the new OBS window in the CamTwist settings then it results in you streaming a black window and no errors will pop. If you exit the OBS application and then relaunch it and try to use the CamTwist virtual camera, the window handle for the OBS window will now be wrong as it's set to the previous instance. The other gotcha is specific to the janky pipeline we set up on the Mac. This may or may not be a problem for you. The first, and already blindingly obvious for those who have followed the steps above, is that OBS put a lot of stress on your CPU, so depending on the spec of the trusty steed that has been issued to you by your corporate overlord you may be out of luck in terms of being able to run the whole OBS pipeline and have enough cycles left to get work done in other applications. Once this is done all that is left is to jump into a video conference and select the CamTwist device as your source webcam and you should be off to the races.īecause computers are hard there are some potential gotchas that are worth calling out so we can avoid harshing your video conference mellow. In CamTwist's preference I have had good experience with using 1024 x 1080 as the resolution and 30fps, though your mileage may vary so definitely experiment. Some additional configuration that is needed is ensuring the size of the output video and its framerate are correct. Once done you should have CamTwist streaming the output from the OBS window as a virtual webcam device. Once you have the selection correctly sized click Done selecting back in the CamTwist window.You should see a black rectangle appear around the edges of the selected app window and you can adjust the rectangle to select the subset of the app window you would like to be seen by others.Select Resizable selection option and then click on Select capture area.In the drop down list select the OBS window.

We are going to set up CamTwist to use a selectable region of the OBS main window that is being displayed on the desktop and outputting the composite scene.

This video source type allows us to select a whole desktop, a specific app, or selectable region of either to be used as a video source. Camtwist itself has a number of different things it is able to use as a video source, and one of them is Desktop+.

The lack of a virtual webcam plugin in OBS's Mac app means we have to achieve similar functionality outside of the OBS app, CamTwist is a popular virtual webcam app for macOS and can help us bridge this gap. On a Mac however things are way less straightforward and the string and Sellotape come out pretty quickly.

In Windows this is all made really straightforward as there is an OBSplugin that is available to create a virtual webcam device within OBS, the plugin is called OBS-Virtualcam and if Windows is your jam then you are pretty much home and dry. Overall this pipeline gives us a fairly simple (albeit janky AF) approach to being able to stream in any video chat client as you are just presenting the composite stream as a webcam device just like any other.

The virtual device is set as the video source for the video conferencing client.

OBS outputs the combined video + overlays via a virtual webcam device.

OBS takes the webcam feed and composites it along with whatever overlays and animations that are set up.

The hardware webcam picks up the image and is set as a 'Video Capture Device' source in OBS.

The rough pipeline for this approach looks as follows: So now we know what OBS is, how do we convince it to play nice with video conferencing apps? The easiest way I found was to go the route of getting OBS output to show through a virtual webcam that can in turn be used as a video source for the video conferencing client. How Do I Make It Work In A Video Conference App?
