On Windows I'm successfully using VideoInputFrameGrabber.getDeviceDescriptions()

Now since VideoInputFrameGrabber is only available on Windows, I tried to use OpenCVFrameGrabber and FFmpegFrameGrabber for Mac OS X.

Now getting:

java.lang.UnsupportedOperationException: Device enumeration not support by OpenCV.

..respectively..

java.lang.UnsupportedOperationException: Device enumeration not support by FFmpeg.

when trying to getDeviceDescription().

Is there any solution? I need the device description ...

Thanks!

FFmpeg has some support for listing devices: https://trac.ffmpeg.org/wiki/Capture/Webcam

We just need someone to make a contribution :)
