True P2P voice- and video phone calls without the need for accounts or access to the Internet. There is no discovery mechanism, no meshing and no servers. Just scan each others QR-Code that will contain the contacts IP address. This works in many off-the-grid networks such as community mesh networks but also in company networks or at home.
在原工程上，增加screen share屏幕分享+h265硬编码设置的功能，增加了使用系统内部audio录制(非麦克风)。 实现方式：业务层使用 ForegroundService + mediaProjection + AudioRecord 录制system audio，不修改webrtc sdk源码。
Features:
- voice and video calls
- no accounts or registration
- encrypted communication
- database backup and encryption
- add custom addresses to reach contacts
Limitations:
- no calls through firewalls / NAT borders
- no calls after MAC / IP address change

Meshenger connects to IP addresses in a true P2P fashion. Contacts are shared via QR-Code. They contain a name, a public key and a list of MAC/IPv4/IPv6 addresses or domain names. By default, only a single MAC address is transferred and used to create an IPv6 link local address (among others) to establish a connection. This does not even need a DHCP server. The exchanged public key is used to authenticate/encrypt signaling data to establish a WebRTC session that can transmit voice and video.
