Windows操作系统做网络转发太不直接了，而且要形成脚本还挺不好写。而且作者只会Linux方式的iptables配置。 45 | 46 | 2. 再有，作者自己用的是树莓派3（类似单片机的超小型电脑），所以Windows也不好用。 47 | 48 | 3. 再再有，如果有大拿愿意移植到openwrt，让路由器实现这个功能，用我这个方案也是可以的。 49 | 50 | 51 | # 需要会什么 52 | 53 | 一些Linux的基础知识，一些shell脚本以及目录知识。 54 | 55 | 如果不会这些，请直接使用镜像教程： https://www.psnine.com/topic/32642 56 | 57 | 最新的镜像release： https://github.com/Tilerphy/ps4broadcast/releases 58 | 59 | 如果Twitch绑定不上需要科学上网，请去qq群383701265找我，我能提供一个临时的代理。 60 | 61 | # 准备工作 62 | 63 | Debian 8 或者 Raspbian（树莓派操作系统，debian的ARM编译）的电脑或者树莓派或者虚拟机，这台电脑的ip假设是`192.168.0.8` 64 | 一台其他的电脑或者虚拟机的运行机器 65 | 66 | Nodejs 6+ 建议直接到Nodejs v8.7.0 67 | 68 | # 局域网真实IP，网卡设备号 69 | 70 | 执行ifconfig获取到当前的网卡地址，一般是eth0也有一些是eth1,或者enp0s3什么的, 类似 71 | ``` 72 | eth0: flags=4163 mtu 1500 73 | inet 192.168.0.8 netmask 255.255.0.0 broadcast 192.168.255.255 74 | inet6 fe80::2e0:66ff:fee7:e31b prefixlen 64 scopeid 0x20 75 | ether 00:e0:86:f7:e3:1b txqueuelen 1000 (Ethernet) 76 | RX packets 20558634 bytes 16007006847 (14.9 GiB) 77 | RX errors 0 dropped 0 overruns 0 frame 0 78 | TX packets 17867778 bytes 15731185654 (14.6 GiB) 79 | TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 80 | 81 | ``` 82 | `eth0`就是网卡的设备号 83 | `192.168.0.8` 就是这台机器的真实IP 84 | 85 | # 着手准备 86 | 1. 执行`apt-get install -y git sudo tar libnet-ifconfig-wrapper-perl xz-utils`安装工具，sudo的用处是以管理员身份来执行命令。 87 | 2. 为了方便起见在`/`目录下创建一个目录 `mkdir /ps4broadcast` 88 | 3. 进入这个目录`cd /ps4broadcast` 89 | 4. `git clone https://github.com/Tilerphy/ps4broadcast.git` 90 | 5. 下载最新的nodejs源代码,并且编译安装 91 | 92 | ``` 93 | wget https://nodejs.org/dist/v8.7.0/node-v8.7.0.tar.gz 94 | tar -xvf node-v8.7.0.tar.gz 95 | cd node-v8.7.0 96 | sudo ./configure 97 | sudo make && sudo make install 98 | ``` 99 | 100 | 执行 `node -v` 得到的结果应该是`v8.7.0`或者其他版本号。 101 | 102 | # 准备完成，检查 103 | 此时目录结构应该是 104 | ``` 105 | /ps4broadcast 106 | /ps4broadcast/node-v8.7.0 107 | /ps4broadcast/ps4broadcast 108 | ``` 109 | 110 | # 继续 111 | 更改脚本的执行权限 112 | ``` 113 | cd /ps4broadcast/ps4broadcast 114 | sudo chmod 777 install.sh 115 | sudo chmod 777 start-web.sh 116 | 117 | ``` 118 | 119 | 执行安装脚本 120 | ``` 121 | sudo ./install.sh 122 | sudo npm install 123 | ``` 124 | 125 | # 开始直播？ 126 | 127 | 0. Twitch 128 | 129 | 在什么都没做的情况下，在PS4上开一个游戏，按手柄的share键，选择“播放游玩画面”，选择twitch，如果之前没有进行过twitch直播，此时会要求你注册一个twitch账号。请根据提示一步步注册一个账号，并且`记住你的twitchid` 130 | 131 | 1. 斗鱼 132 | 133 | 首先打开要去直播的网站，目前只有斗鱼，进入自己的直播间，在自己的直播屏幕上方有一个“直播开关”，点一下on。 134 | 然后界面会刷新，然后再自己的直播间屏幕左上方会找到一个“直播码”的按钮，按一下，会弹出一个框。 135 | 136 | 其中rtmp地址我们称之为 `url` 137 | 138 | 直播码我们称之为 `code` 139 | 140 | 2. 我们的服务器 141 | 142 | 这里需要用到设备号，假设之前获取到的设备号是`eth0` 143 | 144 | ``` 145 | cd /ps4broadcast/ps4broadcast 146 | 147 | sudo ./start-web.sh eth0 148 | 149 | ``` 150 | 151 | 3. Control Panel 152 | 153 | 打开http://192.168.0.8:26666/ 154 | 155 | 填入`Twitch ID`（Twitch的登录名），与 `Douyu Room Id`（斗鱼直播间号） 156 | 157 | 将斗鱼那边得到的 `url` 和 `code` 填入后，点击`reset live` 158 | 159 | 如果得到`LIVING STATUS: true`说明一切运行正常（更新的版本显示的是`n channels.`） 160 | 161 | ![](https://github.com/Tilerphy/ps4broadcast/blob/master/help.png) 162 | 163 | 4. PS4 164 | 165 | 设置->网络->LAN或者无线->自定 166 | 167 | 按照这样设置： 168 | ``` 169 | IP: 192.168.200.45 170 | 掩码(Netmask): 255.255.255.0 171 | 网关（Gateway）: 192.168.200.1 172 | Primary DNS: 114.114.114.114 173 | ``` 174 | 然后一路下一步。 175 | 176 | 找到个游戏，按手柄的share键，选择“播放游玩画面”，选择twitch，一路下一步。 177 | 178 | 如果斗鱼那头没有效果，可能是斗鱼的直播码过期，毕竟只有5分钟有效期，过期不用就作废，所以请重新申请`url`和`code`，填入Control Panel，点击`reset live`，然后重新再PS4上开始直播。 179 |

STT序列化规定如下: 155 | 156 | 1. 键key和值value直接采用`@=`分割 157 | 2. 数组采用`/`分割 158 | 3. 如果key或者value中含有字符`/`， 则使用`@S`转义 159 | 4. 如果key或者value中含有字符`@`， 则使用`@A`转义 160 | 161 | ```javascript 162 | //引入类库 163 | const stt = require('douyudm').stt 164 | 165 | //序列化测试数据 166 | const obj = { 167 | type: 'chatmsg', 168 | nn: '河马（￣。。￣）', 169 | ic: 'avatar_v3/201912/b99d77251eb643b5a88bb81863afea4e', 170 | cst:

坑太多了，github上的库大部分都是不能使用的，如果近期更新的可以判断使用的新接口，review了几乎所有相关的库，都是依据斗鱼自己官方平台的方法发起tcp连接？但根本连不上，一直拒绝... 205 | 206 | 看了下能使用的库，都是通过websocket建立的连接，立马修改，不出片刻撸完，发现发送数据的格式有点难搞，虽说示意图挺清楚的，但是用Buffer传输死活没有相应的消息，调试太磨人心性了，玛德，直接去把斗鱼网页上的方法扒下来。 207 | 208 | 通过webpack打包混淆代码乍一眼看去很混乱，其实仔细观察还是有规律寻找的。 209 | 210 | 文档中编码的几个固定参数均为数字，在webpack中数字的混淆我还没见过，按这个思路精准的找到这段代码。经过我十几分钟的理解，提取出 [**bufferCoder.js**](src/bufferCoder.js) 211 | 212 | 斗鱼自有的序列化，反序列化方法可以查看 [**stt.js**](src/stt.js) 213 |

// just require me before use 40 | 41 | const buffer = new TextEncoder().encode('Turn me into UTF-8!'); 42 | // buffer is now a Uint8Array of [84, 117, 114, 110, ...] 43 | ``` 44 | 45 | In Node v5.1 and above, this polyfill uses `Buffer` to implement `TextDecoder`. 46 | 47 | # Release 48 | 49 | Compile code with [Closure Compiler](https://closure-compiler.appspot.com/home). 50 | 51 | ``` 52 | // ==ClosureCompiler== 53 | // @compilation_level ADVANCED_OPTIMIZATIONS 54 | // @output_file_name text.min.js 55 | // ==/ClosureCompiler== 56 | 57 | // code here 58 | ``` 59 | -------------------------------------------------------------------------------- /douyu/fast-text-encoding/compile.sh: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env sh 2 | 3 | google-closure-compiler \ 4 | --compilation_level ADVANCED \ 5 | --js_output_file text.min.js \ 6 | --language_out ECMASCRIPT5 \ 7 | --warning_level VERBOSE \ 8 | --create_source_map %outname%.map \ 9 | --externs externs.js \ 10 | text.js 11 | -------------------------------------------------------------------------------- /douyu/fast-text-encoding/externs.js: -------------------------------------------------------------------------------- 1 | 2 | /** 3 | * @constructor 4 | */ 5 | var Buffer;
