PS5用户直播只能用采集卡或者直接推送到twich或者youtube，无意中看到B站有同学用PS5直接推送到B站，但是需要一些技术门槛，按照那个同学的思路整理了自己直播到B站的方式

思路

PS5推流到nginx-rtmp，再从nginx-rtmp推流到B站，但是这样的话弹幕看到，所以搞了个IRF转发的代码段。

PS5跟twitch服务器发送相互数据如下:
1.PS5发送PASS
2.irc回复特定内容
3.PS5发送JOIN
4.irc回复特定内容（据实际观察，3、4步重复两次）
前四步已经建立了信任连接，之后就是irc单向往PS5发送消息
那么我们自己建一个irc服务器，跟PS5交互就行

步骤

使用抽取B站直播间弹幕的用的是https://github.com/xfgryujk/blivedm，也可以看我的github，里面有以下代码文件

1.simple.py中直播间号码改成自己的

TEST_ROOM_IDS = [
    22509403,
]

2.simple.py中添加像irf发送弹幕代码

def send(bmsg):
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 建立连接:
    s.connect(('10.255.1.101', 6667))
    s.send(bmsg.encode('utf-8'))
    s.close()

3.simple.py中async def _on_danmuku下面添加代码

send(":" + message.uname +"!" + message.uname + "@" + message.uname + ".tmi.twitch.tv PRIVMSG  " + "#willwillwang :"+ message.msg + "\r\n")

4.Irc服务器程序

import socket
import os
from threading import Thread
import threading

clients = set()
clients_lock = threading.Lock()

def listener(client, address):
    print ("Accepted connection from: ", address)
    with clients_lock:
        clients.add(client)
    try:
        while True:
            data = client.recv(1024)
            if not data:
                break
            else:
                print (repr(data))
                if b'PASS' in data:
                    msg = """:tmi.twitch.tv 001 willwillwang :Welcome, GLHF!
:tmi.twitch.tv 001 willwillwang :Welcome, GLHF!
:tmi.twitch.tv 002 willwillwang :Your host is tmi.twitch.tv
:tmi.twitch.tv 003 willwillwang :This server is rather new
:tmi.twitch.tv 004 willwillwang :-
:tmi.twitch.tv 375 willwillwang :-
:tmi.twitch.tv 372 willwillwang :You are in a maze of twisty passages, all alike.
:tmi.twitch.tv 376 willwillwang :>
"""             
                    data = msg.encode('ascii')
                if b'JOIN' in data:
                    msg = """:[email protected] JOIN #willwillwang
:willwillwang.tmi.twitch.tv 353 willwillwang = #willwillwang :willwillwang
""" 
                    data = msg.encode('ascii')
                with clients_lock:
                    for c in clients:
                        c.sendall(data)
                        print(data.decode('utf-8'))
    finally:
        with clients_lock:
            clients.remove(client)
            client.close()

host = '0.0.0.0'
port = 6667

s = socket.socket()
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host,port))
s.listen(3)
th = []

while True:
    print ("Server is listening for connections...")
    client, address = s.accept()
    th.append(Thread(target=listener, args = (client,address)).start())

s.close()

注意

把上面willwillwang的部分更改为自己twitch账号
