Use bluetooth game controller to play/stop video in unity vr - unity3d

Question

I have created a vr app in unity using google vr sdk. Currently i could click on the screen to start the video. When i use the vr headset, i need to use the bluetooth controller to play/stop the video. Can someone help me do this?

You need to identify how unity map your controller buttons, once you identify what button do you want to press and how unity mapped in his Input Manager (Edit->Project Settings->Input) you just need to call you function from the Update like this:
void Update()
{
if(Input.GetButtonUp("Fire1"))
{
playVideoFuncion();
}
}
Where playVideoFunction() is your own fuction.
In this example I used "Fire1" but maybe in your case is different.
For example for the Xbox Controller you have this configuration explained in Xbox 360 Controller Input on Unity
If you can't find anything related on your controller you can do something like:
void Update()
{
if(Input.GetButtonUp("Fire1"))
{
Debug.Log("Fire 1 Pressed");
}
if(Input.GetButtonUp("Fire2"))
{
Debug.Log("Fire 1 Pressed");
}
if(Input.GetButtonUp("0"))
{
Debug.Log("Button 0 pressed");
}
// Add more buttons and logs
}
There are maybe other ways to identify the input from random controllers but I don't know how. I needed the mapping for the Xbox controller and that page was useful.

You can create a script and attach to the video player so that when a user clicks on the player the commands are run. I assume you already have the unity package for Google VR(GVR). Add the following sample script and modify to suit your need.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class VideoPlayer : MonoBehaviour {
private bool _isPlaying;
// Use this for initialization
void Start () {
_isPlaying = false
}
// Update is called once per frame
void Update () {
if (GvrController.ClickButtonUp && _isPlaying) {
PlayVideo();
}
else if (GvrController.ClickButtonUp && !_isPlaying){
StopVideo ();
}
}
public void PlayVideo{
//Logic to Play Video
}
public void StopVideo{
//Logic to Stop Video
}
}
