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.

error cross compiling #102

Closed jonspieg closed 4 years ago

jonspieg commented 4 years ago

I followed the great cross compiling readme, but unfortunately I got stuck on the last and most important task - building RWS :o I'm using webrtc from the commit mentioned here https://github.com/kclyu/rpi-webrtc-streamer/commit/8ff2e5d6a92fdfd70b19d38def379b5833362467 I noticed that the trigger for this error (which is EncoderSelectorInterface) was added in the last commit to raspi_encoder.h Any help would be appreciated

Thanks!

Ok got it I was on the wrong webrtc native branch switched to the one mentioned here https://github.com/kclyu/rpi-webrtc-streamer/commit/4a64301c886d953b72792b6f6f0082d45b672c72 and it compiles now
