I’ve built mediasoup-broadcaster-demo with vs2017, windows 10. but, when I run a broadcaster.exe, failed to connect server. After debugging the source code, I noticed that error code is returned like below. auto r = cpr::GetAsync(cpr::Url{ baseUrl }).get(); ![image](https://global.discourse-cdn.com/free1/uploads/mediasoup/original/1X/844f224490ba3ed69a4fb2c426c88e025aebedd1.png) code=SSL\_CACERT\_ERROR(13) message=“SSL certificate problem: unable to get local issuer certificate” What is the reason? Please help me. ---

Have you correctly set your SSL certificates in the config file? ---

How can I compile the instruction in main() on windows. (void)sigsuspend(nullptr); Is it possible to run mediasoup-broadcaster-demo in windows 10? ---

Ok, Thanks. But what about the compile error with sigsuspend()? How can I solve this problem? _error C3861: ‘sigsuspend’: identifier not found_ ---

Thank you. I’ve some questions. Are there two online demo servers for a web client app and a c++ app? Is it possible to connect to demo server with both web client and c++ client? And what about creating a consumer to web client’s producer in c++ client? ---

It’s a single web server. BTW please use your own deployment instead of using our demo server. It’s just for demo purposes, we may shutdown it at any time, and it costs us money based on traffic. ---

Ok, I’m sorry But Is it impossible to consume other peer’s producer(mediasoup-demo) in my app based libmediasoupv3? I’ve already make mediasoup server on the cloud and using my own. ---

> [@ming](#): > > But Is it impossible to consume other peer’s producer(mediasoup-demo) in my app based libmediasoupv3? Of course it’s possible. But mediasoup-broadcaster-demo is just a demo for a specific use example and does not do what you look for. You need to do it yourself. ---

What does the broadcaster demo actually do, I’ve read everything, but it is not clear. Does it just addd the ability to broadcast a prerecorded video? (I can achieve that with screen sharing on the standard demo.) Please can someone enlighten me? ---

Man, it’s **the first thing** on the README in the [broadcaster’s github repo](https://github.com/versatica/mediasoup-broadcaster-demo): # mediasoup broadcaster demo (libmediasoupclient v3) [libmediasoupclient](https://github.com/versatica/libmediasoupclient) based application that produces artificial sound and video to the specified room in [mediasoup-demo](https://github.com/versatica/mediasoup-demo) [mediasoup-demo](https://github.com/versatica/mediasoup-demo) application. The video consists of some colored rectangles moving towards the lower-right corner of the image.
