Running this manual test, you should be able to record a 5-sec long video stream from your webcam and then play it using ffplay (you need to have ffmpeg installed).
To run manual tests, you need to install dependencies:
$ mix deps.get
And run manual (you observe the result and decide whether it works) tests:
$ mix test --include manual
If run successfully, you should be able to see video recorded by your camera.
You might be asked to grant access to your camera, as some operating systems require that
In case of the absence of a physical camera, it is necessary to use a virtual camera (e.g. OBS, see how to set up the virtual camera in OBS)
