This is an iOS and Android native project that demonstrates how to use WEBRTC and SRS for RTC transport.

Usage:
mkdir build
cd build
git clone https://github.com/ossrs/srs.git
cd srs/trunk
./configure --osx
make

cd conf
vim debug_rtc_remote_https.conf
or
vim debug_rtc_local_https.conf

or
./objs/srs -c conf/debug_rtc_local_https.conf

// stop srs.
./etc/init.d/srs stop
