1AVCapture allows you to capture audio or video from any source available on your system and it also allows you to combine video and audio. So, as you can see, there are innumerous possibilities of capture sources available but without capture profiles there would be no means of keeping all of them available for you to switch at any time. That's what a capture profile is used for.
1AVCapture will analyze your hardware and create a number of capture profiles that you can use right out-the-box.
Nineteen capture profiles are available.
Each capture profile will have at least one video or audio source and can also have both.
