Hi, I’m facing an issue with very first step of using libmediasoupclient. When I try to load rtpCapabilities into Device instance then I get std::bad\_alloc and stack trace as in screen ![image](https://global.discourse-cdn.com/free1/uploads/mediasoup/original/2X/f/f298e978063f33a80df3f79f5bb2b9ea85105735.png) Do you have any ideas what could be wrong? ---

Hi, Are you using the exact libwebrtc version indicated in the docs? ---

yes, m84 - double checked it yesterday. Does --args matters for this? I’ve checked some but not sure what are recommended for Win + VS2019. Are those below ok in your opinion? gn gen out\m84 --args=“is\_debug=false is\_component\_build=false rtc\_build\_examples=false rtc\_include\_tests=false rtc\_build\_ssl=false rtc\_ssl\_root=“C:\Program Files (x86)\OpenSSL\include” use\_rtti=false use\_custom\_libcxx=false treat\_warnings\_as\_errors=false is\_clang=false” ---

There are some args examples in the docs: > **[mediasoup :: Installation](https://mediasoup.org/documentation/v3/libmediasoupclient/installation/)** > > Cutting Edge WebRTC Video Conferencing ---
