Qt重写webrtc的demo peerconnection

整个demo为：

可以选择多个编码方式：

其中h264在cmake中要加上-DWEBRTC_USE_H264，编译时的参数为

复制代码

gn gen out/release --ide=vs --args="is_debug=true use_custom_libcxx=false rtc_enable_protobuf=false target_cpu=\"x64\" enable_iterator_debugging=true symbol_level=2 is_clang=true rtc_include_tests=true rtc_use_h264=true ffmpeg_branding=\"Chrome\" proprietary_codecs=true"

需要打开webrtc选项。这个demo的下载链接为
