First try this demo can play on ios

Second
https://github.com/phoboslab/jsmpeg#encoding-videoaudio-for-jsmpeg
view-stream.html (nodejs localhost:8080 maybe can see)
websocket-relay.js this is use node.js then get ws server
Import !!
ffmpeg -re -i rtmp://xxx.xxx.xxx.xxx/live/ooo -f mpegts -codec:v mpeg1video -bf 0 -codec:a mp2 -s 640x360 -r 30 -q 4 -muxdelay 0.001 http://localhost:8081/password -re 參數表示以視頻實際播放速率解碼，不加這個參數一般會導致直播速率變得飛快
-re一定要加，代表按照帧率发送，否则ffmpeg会一股脑地按最高的效率发送数据。
-muxdelay 0.001 reduce lag (maybe no use)
-q 4 Need test
You’re setting -q 1, which is the best possible quality.

====低延时配置======
https://github.com/ossrs/srs/wiki/v2_CN_LowLatency
考虑GOP-Cache和累积延迟，推荐的低延时配置如下（参考min.delay.com）：
# the listen ports, split by space. listen 1935; vhost __defaultVhost__ { gop_cache off;
queue_length 10;
min_latency on;
mr { enabled off; }
mw_latency 100;
tcp_nodelay on; }
当然，服务器的性能也要考虑，不可以让一个SRS进程跑太高带宽，一般CPU在80%以下不会影响延迟，连接数参考性能。

這套大概是目前可以把rtmp轉成websocket和webrtc
https://wcs5-eu.flashphoner.com/dashboard.xhtml
這是他的deom，Streamer就是把攝像頭和聲音轉成html5 (websocket、webRTC)能接收的
有下載 web call server 5.0 但要序號，問官方，說沒試用
