Can we built a triple cam app in android ?

[Android Central Question]

Is there any possibility to build a triple camera application which consists of two inbuilt cameras (front&rear) and a web camera, and all of the cameras should work simultaneously to record a video .

There's no hardware to feed video into, so the webcam (or CCTV cam or an other external cam) is out.

You may be able to capture images from both the front and back cameras at the same time - but they won't be looking in the same direction, so they won't both record the same scene. (And syncing the two streams, if you have to do any editing, is something they probably wouldn't try in Hollywood.) Record with 2 or 3 phones or cameras, then use A/B roll to combine the streams. (You'll need a video editing box to do that.)

I have done something similar in Unity using WebcamTexture to render the front and rear camera to 2 different textures.

You can use a standard USB webcam on an android phone with an OTG adapter. But I can tell you from experience though that getting an external OTG webcam to work is a pain.

But here's a good starting point...
