TURN 协议全称Traversal Using Relays around NAT(使用中继穿透 NAT),STUN 的中继扩展。简单的说,TURN 与 STUN 的共同点都是通过修改应用层中的私网地址达到 NAT 穿透的效果,异同点是 TURN 是通过两方通讯的“中间人”方式实现穿透。上面提到的 relay 服务就是通过 TURN 协议实现的,所以 relay 服务器和 TURN ...
所以为了适配不同的平台,WebRTC提供了SDK层,Linux平台基于使用GTK的c++,MAC和IOS平台基于使用cocoa库的Object c,android平台基于JAVA,为了让这些平台都能够调用c/c++核心函数,WebRTC提供了android和object c的封装层,这称为SDK层,android中使用了JNI机制使得UI层的JAVA程序和实现核心功能的c/c++程序可以互相调用,类似...

没错,我们还需要TURN(Traversal Using Relays around NAT,在NAT周围使用中继遍历) ,它是STUN的一个扩展,添加了Relayd功能;有了它,就可以解决上面的这个问题了 在STUN分配公网IP失败后,可以通过TURN服务器请求公网IP地址作为中继地址。关于TURN的详细介绍,大家可以看官网手册: ...

on a slice server to accommodate 1 to 3 seconds delay, or even achieve the 500ms to 1 second low-latency in the live streaming, the RTC of 200ms to 500ms calls, and control scenarios within 100ms. These scenarios can only be implemented using a stream server, regardless of whether the...
A source delivers YUV frames, which the framework converts to I420 format and queues on the output plane of the encoder. The output plane buffers are sent to NvEncoder using proprietary NVIDIA low-level encoding libraries. NvEncoder returns filled encoded buffers on its capture plane....
Everything else works exactly the same way as on Linux. Configure and start To start the server, you can use thejanusexecutable. There are several things you can configure, either in a configuration file: <installdir>/etc/janus/janus.jcfg ...
