no i am working on chrome on android, and the code works correctly in brfv4 but the mobile camera (samsung chrome) is opened as front cam. i need to open the rear cam in the code on brfv4

So you already tried

"facingMode": "environment"

for the camera constraint?

[AlaaElZein]

where should i add this variable? i searched in all the downloaded brfv4 project and there is no existed variable called facing mode in the js.

It's a webcam constraint.

In this file:

https://github.com/Tastenkunst/brfv4_javascript_examples/blob/master/js/utils/BRFv4SetupWebcam.js

line 28:

webcam.constraints = {video: {width: width, height: height, frameRate: fps}};

should be:

webcam.constraints = {video: {width: width, height: height, frameRate: fps, facingMode: "environment"}};

Hi, can easily this be dynamically changed? so the user can choose their camera?

Look into facingMode. Set the desired facingMode the first time and then have a toggle button that switches between environment and user.
