你好，我试了你给的这个网址，没能重现问题。你能把裁剪结果贴上来？

如下是内容：

MAC使用Nginx搭建RTMP服务器 - 简书

1、先安装homeView

安装命令ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"移除命令ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

2、安装Nginx服务器

增加对 nginx 的扩展;也就是从github上下载,home-brew对ngixnx的扩展

brew tap homebrew/nginx

3、安装Nginx服务器和rtmp模块,安装过程有点久。稍等。

brew install nginx-full --with-rtmp-module

4、查看nginx的信息

brew info nginx-full

nginx的安装位置

/usr/local/Cellar/nginx-full/1.10.1/bin/nginxnginx配置文件所在位置/usr/local/etc/nginx/nginx.confnginx服务器根目录所在位置  /usr/local/var/www

使用命令开启nginx：

nginx

在浏览器地址栏输入：http://localhost:8080 （直接点击）

图1.jpg

5、配置rtmp

open /usr/local/etc/nginx

打开niginx的文件夹，找到nginx.conf文件,用xcode打开。添加下面配置

#在http节点下面(也就是文件的尾部)加上rtmp配置：rtmp {#协议名称    server {#说明内部中是服务器相关配置        listen 12345;#监听的端口号, rtmp协议的默认端口号是1935        application zbcs {#访问的应用路径是 zbcs        live on; #开启实时        record off;#不记录数据        }    }}

6、保存文件后，重新加载nginx的配置文件。

重要操作！一定要重启nginx

nginx -s reload

7、安装ffmepg工具

brew install ffmpeg

8、推流

ffmpeg -re -i /Users/mazaiting/Downloads/台球.mp4 -vcodec copy -f flv rtmp://localhost:12345/zbcs/room

其中abcs是配置文件中的应用名，12345是配置文件中的端口，room可以随便写，"/Users/mazaiting/Downloads/台球.mp4"是推流的视频。

9、观看

使用软件VLC MediaPlayer打开网络串流，Open Media...->Network，输入rtmp://localhost:12345/zbcs/room，点击Open进行观看。

我猜测你的 markdown 查看软件，无法正确识别换行符 \n。下面是我裁剪这个网页后，把文件读出来。你可以看到文本 "安装命令" 的后面是有个换行符 \n 的。

不知道你是不是在 windows 下，windows 的默认文本打开软件「记事本」，无法正确显示换行符 \n。

啊，我知道了，我和你的运行环境不一样，我没有启用脚本，所以我裁剪出来的代码都是 plain，而你的和我不一样。（可是这个网站一启用脚本就白屏）。

mika-cn commented 4 years ago

我实在打不开这个网页。里面的 JS 似乎有问题，也有可能是墙在搞鬼。你能把网页用 html 的格式裁剪下来，然后发到这里吗？

                                            <p style="text-indent:50px;">最近公司有个视频的项目，需要调用FFMPEG的API来实现部分功能，这么多语言用下来，还是C#最舒服，所以就还是希望用C#来写，但C#不能直接调用ffmpeg的静态库，动态库又得采用pinvoke方式，ffmpeg那么多API，还涉及类型转换，要完全实现工作量真不小，开源项目<a href="http://www.baidu.com/link?url=X24d3bnuEtlk69dOLoB-d01xybEA6DgSdtrxTDLaL5TEb-zG6zDBzznZyYC_yNaLvMpWt9E_BwJ2vTj32W4ejK" rel="noopener noreferrer" target="_blank" referrerpolicy="no-referrer">SharpFFmpeg</a>也很久没更新了，版本太老，正要自己实现的时候发现了ffmpeg.autogen这个项目，几乎是全部支持ffmpeg的API，而且一直在更新，所以就采用了这个项目，用下来还真不错。啰嗦了这么多，还是上个简单的例子 。</p>

<p><strong>FFmpeg拉取RTMP流并播放</strong></p>

<p>&nbsp;</p>

<p>&nbsp;</p>

<ul><li>1. 项目添加ffmpeg.autogen引用，nuget可以直接获取到，因为我用的FFmpeg是3.4版本，ffmpeg.autogen也用的3.4版本，如图。</li>
</ul><p><img alt="" class="has" height="782" src="assets/1585390350-a952d88e80e4c56e6e88806609c6d51d.png" width="1200"></p>

<p>&nbsp;</p>

<ul><li>2.创建一个frmPlayer窗体，来显示图像，为了方便，我这里用一个PictureBox来显示图像。</li>
</ul><p>FFmpeg解码后是YUV图像，需通过sws_scale转会成RGB，然后构造成&nbsp;System.Drawing.Bitmap给PictureBox显示。</p>

我尝试修复了这两个问题，打包了个版本，现希望你能在有空时帮忙测试下。如下：

下载 0.1.53 Beta 版

下载下来的文件为 Zip，安装方式见这里

测试了几个网站，发现没有换行的问题已修复。但是附件的html 裁剪为 markdown 后没有了缩进，如下图所示： beta-1.zip

mika-cn commented 4 years ago

@CodingOX

我裁剪了你发给我的 html ，生成的 markdown 里面的代码有缩进。但是你给我的 html 文件里面找不到你截图里面的 BeanWrapper。是不是你上传附件的时候搞错了？

貌似发错了，这个才是 beta-2.zip 不过这 2 篇文章的问题一样，都是剪裁 markdown 后没有缩进。

mika-cn commented 4 years ago

@CodingOX

奇怪，我裁剪下来的都是有缩进的啊，而且你给的 bata-2 里面的代码的缩进用的是 Tab （也就是 \t）。

你用文本编辑器打开，也是这样？

从下图的名字来看，你给的是 beta-1

mika-cn commented 4 years ago

我上条回复指的是你最后传的附件 beta-2.zip（怪我，没说清楚）。我使用了 MaoXian 0.1.52 和 0.1.53-beta1 在 Firefox 和 Chrome 上都没能重现问题，也没有找到可能产生该行为的代码。

我在windows 下测试效果还是没有缩进，很奇怪，原文地址是：https://blog.csdn.net/qq_41907991/article/details/105214244 通过vscode查看也是没有缩进的

mika-cn commented 4 years ago

你把裁剪方式改为浏览器也是这样？

mika-cn commented 4 years ago

你把 support 页面的信息 copy 到这里，我看下你的配置。

altairwei commented 4 years ago

@CodingOX 有可能 WizNotePlus 在将 Markdown 存入 HTML 时，\t 被 HTML 自动删除掉了。你最好用 mx-wc “浏览器” 保存下来看看。

CodingOX commented 4 years ago

剪裁缓存浏览器的 markdown 没有问题了，感觉是 wiznotePlus 的原因！

用浏览器没有该问题产生，看来是 WizNotePlus 的问题，这个怎么办！？

altairwei commented 4 years ago

我大概知道问题的原因了，等我修复吧。

altairwei commented 4 years ago

@CodingOX 你试一下这个修复是否解决了的问题。

下载：src.zip

mika-cn commented 4 years ago

@altairwei

现在 WiznotePlus 是在 MaoXian 这边先把 markdown 嵌入成 html，再在 WiznotePlus 客户端那边转成 Markdown？还是说是 Wiznote 服务器那边转成 Markdown 的？

altairwei commented 4 years ago

WizNote 服务端储存架构就只允许纯粹的 HTML 文件，所以官方支持 Markdown 的方式就是将其储存到 HTML 中，客户端编辑器从 HTML 中将 Markdown 提取出来再渲染。因为 HTML 有很多保留字符，所以这种方式就会导致大量的字符编码和转义问题。

把 Markdown 存进去 HTML，用 <pre><code>$markdownText</code></pre> 应该可以避免转义问题。但是你那边可能情况比较复杂，需要兼容官方的客户端吧。

是的，情况比较复杂。如果用户编辑 Markdown 后，客户端没有按照 <pre><code>$markdownText</code></pre> 格式包装 Markdown ，这又会造成 \t 的丢失。所以目前的解决方案就是将 \t 替换成四个 $nbsp;。

這個 Issue 裏提到的問題，都已經修復並上線。目前 Firefox 擴展中心已經是最新的版本，Chrome 還需要進行人工審核，剛才看上面的公告，受這次冠狀肺炎的影響，人工審核的速度會變慢。

@altairwei 之前發給你的 src.zip 只包含那個修復 Tab 的代碼，我建議你可以先用 zip 包（已更新到最新版 0.1.53）的方式先用着。（傳送門）

另：感謝一直的反饋，在你的配合下，我們修復了 3 個 bug，MaoXian 更好用了一些 :D
