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. Try setting it to 4 or 8 instead.

compression_level (-q)
Set algorithm quality. Valid arguments are integers in the 0-9 range, with 0 meaning highest quality but slowest, and 9 meaning fastest while producing the worst quality. Can put more than 9.

mpegts this is see error, then find some guy say use mpegts. 

Don't use mpeg1video
