Need chatroulette script (on the basis of existing script)

We need a script that is functionally similar to the Chatalternative site.

Here is a script that you can take as a basis and modify: https://github.com/peer-calls/peer-calls
It is necessary to remove some bugs (sometimes the video of the interlocutor is not displayed in some browsers / devices), and make the function of random flipping interlocutors.

We also need filters by gender and region.

Final task conditions:

- no any bugs, all devices support
- responsive layout
- features: random user flipping, filters by gender and region
