This repo's objective is providing something like Web Cam server on the most popular Raspberry PI hardware. By integrating [WebRTC](https://webrtc.org/native-code/) and Raspberry PI, we can stream the Raspberry camera feed to browser or native client which talks WebRTC.

First of all, please follow the procedures in building document. The error message appears because the webrtc build is not done first, and you should use the Cr-Commit-Position specified in the RWS commit log for the WebRTC native package.

Note that the current master is compiled in the WebRTC native code package below.

Cr-Commit-Position: refs/heads/master@{#25867}
WebRTC commit position: b3033c448ffd0d4266dfec636bfc5471baf1e848
