ORTC Lib
Welcome to ORTC Lib.
ORTC Lib is an open source library for
UWP
iOS
, and
Android
for building RTC (Real-Time Communication) applications compatible with other
WebRTC
and
ORTC
browsers (or other on-the-wire compatible technologies).
Optimized for Mobile
ORTC Lib has been designed specifically with mobile applications in mind. The engine is optimized for mobile networks and firewalls, power consumption, CPU, media handling, backgrounding, and logging and statistics.
WebRTC 1.0 API Adapter / Shim
ORTC Lib has a built-in adapter API exposing the standard
WebRTC 1.0 API
while using the ORTC Lib core engine. This allows developers to continue to use the current WebRTC 1.0 API while graduling adapting code to take advantage of all the advanced
ORTC API
capabilities and features.
