抖音直播助手推流码使用wireshark抓包分析
最近想在douy直播游戏，发现下载了douy直播伴侣没有OBS第三方推流选项，然后去哔哩哔哩等网站搜索教程，基本上都是用他们自己自制的软件进行获取推流密钥等，发现还收费，对于白嫖来说非常不友好。于是只能自己动手了！
需要的工具:
1.wireshark
2.visual studio
3.SharpPcap 4.2.0
视频教程:
B站视频教程
开始实操:
1.使用wireshark分析douy直播伴侣，通过过滤rtmpt协议，可以看到直播地址和推流密钥
2.接下来直接上代码!

里面用到了皮肤代码可以自己删除!!!
经常遇到的问题:
- 为什么OBS会一直重连?答:操作有问题，仔细看上面的视频，获取到了推流密钥等直播伴侣不能关播，打开OBS输入推流地址和密钥后点击OBS中的开始推流，然后直接关闭直播伴侣，不能点击关闭直播!
- 为什么软件打不开没反应?答:安装压缩包内的一个软件
- 正确下播步骤:OBS中点击停止推流，然后再次打开直播伴侣会弹出重连，点击确定，然后点击关闭直播。
- 感谢你赐予我前进的力量
