My camera did not work after Flash Player 22

Hello Adobe.

I develop a virtual camera by Windows Directshow. The camera can work with OBS, Skype, Flash Media Live.

I fount that the camera works fine beneath Flash Player 21 but not above 22.

The Flash AIR program can get the camera by "Camera.getCamera()" , but the camera can't get any video.

I checked the Flash Player 22 release notes but with no any information about it.

My OS is Windows 7 64-bit.
