Hello!
1. We will upgrade the UI in 2014.
2. And then, we will support more audio channels.
3. We may not support AAC audio codec in 2014, but anyway, we will support AAC audio in the future.
Thank you for choosing Bandicam!
We've tried topmostcamwindow.Hello
For now I think you can use a utility which displays your webcam feed on a borderless topmost window.
I have been searching for one and found an open source program called topmostcamwindow.
