webrtc 测试可用方案：https://blog.csdn.net/lixiang987654321/article/details/108714690 ：原因：推流采用1935端口推流，否则webrtc播放不了 rtmp://192.168.18.129:1935/live/123
如果简单尝试：推荐 SRS ,部署方便
开源项目：https://github.com/ossrs/srs
WebRTC：https://github.com/ossrs/srs/wiki/v4_CN_WebRTC#config-candidate
Docker
推荐使用Docker直接启动SRS，可用镜像在 这里 :
docker run --rm -it -p 1935:1935 -p 1985:1985 -p 8080:8080 \
ossrs/srs:4 ./objs/srs -c conf/rtc.conf
Note: 若按照文档操作遇到问题，请在 SRS星球 上发文章求助，请贴上本文档链接以及遇到的问题。
若需要支持WebRTC，需要设置CANDIATE，并开启UDP/8000端口：
docker run --rm -it -p 1935:1935 -p 1985:1985 -p 8080:8080 \
--env CANDIDATE="192.168.1.10" -p 8000:8000/udp \
ossrs/srs:4 ./objs/srs -c conf/rtc.conf
Note: 请将CANDIDATE设置为服务器的外网地址，详细请阅读CANDIDATE。
运行后：检查SRS是否成功启动，可以打开 http://localhost:8080/ ，
使用 FFmpeg 或 OBS 推流： ffmpeg -re -i ./doc/source.flv -c copy -f flv -y rtmp://localhost:1935/live/livestream 打开下面的页面播放流（若SRS不在本机，请将localhost更换成服务器IP）: RTMP (by VLC): rtmp://localhost/live/livestream H5(HTTP-FLV): http://localhost:8080/live/livestream.flv H5(HLS): http://localhost:8080/live/livestream.m3u8 H5(WebRTC): webrtc://localhost/live/livestream (隐藏了端口1985 == webrtc://127.0.0.1:1985/live/livestream)
推流工具：OBS（Open Broadcaster Software）
使用：

推流设置
串流密钥即为该流的名：建议 时间＋主旨 例如：20210826baxain发布会

手机推流：
拉流工具
VLC

安装过程略
打开网络串流，填写流的路径/${流名}
数据流的保存：
sudo docker run -itd --name=sea_srs -p 1935:1935 -p 1985:1985 -p 8080:8080 --env CANDIDATE="192.168.18.51" -p 8000:8000/udp registry.cn-hangzhou.aliyuncs.com/ossrs/srs:4 ./objs/srs -c conf/rtmp2rtc.conf
sudo docker run -itd --restart=always --name=my_sea_srs -p 1935:1935 -p 1985:1985 -p 8080:8080 --env CANDIDATE="192.168.18.51" -p 8000:8000/udp \ -v /opt/docker/sftp/upload/p/:/opt/:rw \ registry.cn-hangzhou.aliyuncs.com/ossrs/srs:4 ./objs/srs -c conf/rtmp2rtc.conf
rtmp2rtc.conf

默认数据流是不会被保存的：
可以在
vhost __defaultVhost__ 节点下 添加如下配置：
vhost __defaultVhost__ { dvr { enabled on; #是否开启持久化 #dvr_path /opt/[app]/[stream].[timestamp].mp4; dvr_path ./objs/nginx/html/[app]/[stream][2006][01][02][15][04][05].mp4; dvr_plan session; #dvr_plan segment; dvr_duration 60; dvr_wait_keyframe on; time_jitter full; } rtc { enabled on; # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtmp-to-rtc rtmp_to_rtc on; # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtc-to-rtmp rtc_to_rtmp on; } http_remux { enabled on; mount [vhost]/[app]/[stream].flv; } }
