C++ Remote Control WebRTC Client (Extending with new features) -- 2

1. we already build a unique WebRTC C++ client (Windows) that captures the host desktop & windows and streams in real-time to standard browser peers and even act as remote controller for those remote browser based participants. 2. seeking for ***highly capable C++ WebRTC expert*** to extend EXISTING functionality with advanced cool features such as: a. supporting latest WebRTC 89 library (with latest codec supports, improved video adaption features etc') b. ability to stream host mic/system audio/camera and capture and present remote A/V streams (alternative to our existing js based implementation) c. record single host entire screen + entire A/V streams locally to mp4 file or server mode (record entire room with all participants A/V/SS streams) while managing previous recordings (alternative to our existing js based implementation) d. adding fine-grained control (black/white list of windows & processes allowed/disallowed to remote control by those defined criteria's list) e. adding "portion of screen" capture (similar to zoom and others) f. adding support to share multiple screens at same time (by few RC clients parallelly) g. Add System Tray UI Menu operating independently, instead of existing browser based commands. h. whiteboard tools for Annotate screens / windows while streaming. (finally and optional) i. Mac / Android / IOS run-time porting of current existing codebase.
