在iOS设备上同时使用前置和后置（主要和次要）摄像头

Question

I wanted to know if there is any functionality/app on iOS devices which allows you to capture videos simultaneously using front and back cameras showing the outputs in say a split screen. And then later allowing to merge both videos.

Can this functionality be achieved through a user designed app or through a cydia tweak on jailbroken devices ? This question is simply out of curiosity, any relevant information would be helpful.

Thanks.

Answer 1

Well, video recording is done using AVCaptureSession . So you should try creating two of these, with different input targets each.

Edit: As per this question/answer , it is not possible to create multiple AVCaptureSession s.
