c++ - Attach a video stream onto an existing application -

Is it possible to show a video playing on an existing video?

The application is running.

Get the video A and place it on top of A and then run it.

Thank you! Cheers!

If you want to load a video and want to play it, you can use it You can also use the Windows Codex installed to try playback which you can use to select the codec that can not be installed on the computer.
