rrWeb整体方案

1、整体流程

1.1、流程图

生产负载调用rrWeb情况

前端调用保存录制使用固定地址，调用预生产服务进行保存

定时任务执行，设置地址配置为预生产地址

1.2、功能说明

1.2.1 录制保存功能

地址

/rrWeb/saveRrWeb

功能

1、首次录制，生成本次录制的唯一id

2、同一订单可能存在多个录制id

3、录制id在当前录制流程中唯一，关闭录制或关闭浏览器重新进入开始录制，会生成新的id

4、使用Redis记录录制id每次片段的顺序

5、保存数据到backTrackRecord、backTrackVideo表

6、保存录制数据到服务器中，保存目录/data/service/rrWeb/sava/录制id/片段数据

7、/data/service/rrWeb目录在sys_config表中配置

1.2.2 定时合并数据

地址

/job/convertVideo

功能

1、查询backTrackRecord表中未合并过的数据

2、获取对应录制id

3、根据录制id获取/data/service/rrWeb/sava/录制id/目录下所有的片段数据

4、根据片段录制顺序，读取文件内容，写到/data/service/rrWeb/录制id.txt文件下

5、更新backTrackRecord状态

1.2.3 Linux下定时转换视频

地址

无

功能

1、将/data/service/rrWeb/下对应的文件备份到history目录

2、使用rrvideo命令，将对应文件转换为视频，保存到/data/service/rrWeb/mp4下

3、转换过程超过2分钟的停止

4、转换完成删除/data/service/rrWeb/下对应文件

配置脚本执行

<code># 打开定时任务配置文件

crontab -e

# 在配置文件中写入定时任务的操作, 这里就是指定每天1点10分定时执行脚本，并把执行脚本的日志写入文件 crontabLoad.log

10 1 * * * sh /data/service/rrWeb/start.sh > /data/service/rrWeb/crontabLoad.log 2>&1

脚本

#!/bin/bash

# 这个很重要，不引用环境变量，脚本执行rrvideo时会报错找不到命令

source /etc/profile

#set -x

INPUT_DIR=/data/service/rrWeb

OUTPUT_DIR=/data/service/rrWeb/mp4

HISTORY_DIR=/data/service/rrWeb/history

TIMEOUT=120 # 2分钟超时

time=$(date -d "7 minute ago" +"%Y-%m-%d %H:%M:%S")

echo "${time} :开始执行rrWeb转视频"

files=$(ls $INPUT_DIR/*.txt | wc -l);

if [ "$files" != "0" ]; then

for f in $INPUT_DIR/*.txt; do

filename=$(basename "$f")

echo "当前转换filename：${filename}"

# 复制到history目录

cp "$f" "$HISTORY_DIR/$filename"

nohup rrvideo --input "$f" --config "$INPUT_DIR/rrvideo.config" --output "$OUTPUT_DIR/${filename%.*}.mp4" &

pid=$!

timeout=$TIMEOUT

while ps -p $pid > /dev/null; do

sleep 1

timeout=$((timeout-1))

if [ $timeout -eq 0 ]; then

kill -9 $pid

echo "killed ${filename}"

break

fi

done

if [ $timeout -ne 0 ]; then

# 删除txt文件

rm "$f"

fi

echo "Finished $f to $filename.mp4"

done

else

echo "没有要转换的文件"

fi

# 关闭无头浏览器进程

PID=`ps -ef | grep puppeteer | awk '{print $2}'`

echo "得到进程ID：${PID}"

echo "结束进程"

for id in ${PID}

do

kill -9 ${id}

echo "killed ${id}"

done

echo "结束进程完成"

echo "执行rrWeb转视频结束"

rrvideo.config

"width":1280,

"height":720,

"speed": 1,

"skipInactive": true,

"mouseTail": {

"strokeStyle": "green",

"lineWidth": 2

},

"startDelayTime": 1000

}

1.2.4 定时上传OBS

地址

/job/uploadVideoToObs

功能

1、查询backTrackVideo表中未上传OBS的数据

2、3天内还未上传到OBS，进行告警

3、根据录制id获取/data/service/rrWeb/map目录下的视频文件

4、获取视频流，上传OBS

5、 更新backTrackVideo表OBS视频地址

缺少其他库文件解决方法

# 如缺少libpcre.so.1文件

一种是安装libpcre.so.1对应的软件，

一种是获取libpcre.so.1库文件并放置在 /lib64目录下。

最后一种是获取libpcre.so.1库文件库文件并上传至服务器A任意目录下上并设置LD_LIBRARY_PATH变量

方法一：获取软件并设置LD_LIBRARY_PATH变量方法。如下：

Step1：从服务器B上下载libpcre.so.1对应软件，上传至服务器A上任意目录下。如/opt。

Step2：设置LD_LIBRARY_PATH变量。执行export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt。说明：LD_LIBRARY_PATH是Linux环境变量名，该环境变量主要用于指定查找共享库（动态链接库）时除了默认路径之外的其他路径。

Step3：重新执行程序，问题解决。

方法二：获取软件并放置指定目录下。如下：

Step1：从服务器B上下载libpcre.so.1对应软件，上传至服务器A上的/lib64目录下。/lib64为步骤（2）中查出缺失文件的目录。

Step2：重新执行程序，问题解决。

方法三：安装libpcre.so.1对应的软件方法如下：

Step1：在服务器B上执行rpm -qf /lib64/libpcre.so.1。

[root@www ~]# rpm -qf /lib64/libpcre.so.1

libpcre-3.2-21.el5 --> 说明libpcre.so.1文件是通过安装libpcre-3.2-21.el5获取。

Step2：查看Linux服务器系统版本，获取对应的镜像包，从而获取libpcre-3.2-21.el5.rpm安装软件

Step3：执行rpm -ivh libpcre-3.2-21.el5.rpm安装。

Step4：重新执行程序，问题解决。

2.4、使用rrvideo转换视频问题

2.4.1、rrvideo源码

},

});

});

}

2.4.2、问题一：rrvideo默认转换超时时间为30秒，调整为无超时时间，超时时间通过脚本进行控制

// 在index.ts中的public async init()方法增加

await this.page.setDefaultNavigationTimeout(0);

全方法

public async init() {

try {

this.browser = await puppeteer.launch({

headless: this.config.headless,

});

this.page = await this.browser.newPage();

// 增加设置超时时间为0

await this.page.setDefaultNavigationTimeout(0);

await this.page.goto("about:blank");

await this.page.exposeFunction("onReplayStart", () => {

this.startRecording();

});

await this.page.exposeFunction("onReplayFinish", () => {

this.finishRecording();

});

const eventsPath = path.isAbsolute(this.config.input)

? this.config.input

: path.resolve(process.cwd(), this.config.input);

const events = JSON.parse(fs.readFileSync(eventsPath, "utf-8"));

await this.page.setContent(getHtml(events, this.config.rrwebPlayer));

} catch (error) {

this.config.cb("", error);

}

}

2.4.3、问题二：转换后的视频抖动问题，有白边

白边问题为puppeteer默认打开浏览器的大小与rrvideo播放器的大小冲突导致

puppeteer打开的页面默认的窗口大小是800*600，与rrWeb-player的窗口大小不符合导致的白边问题

// 在index.ts中的public async init()方法增加 窗口可以设置1280*720 或者1920*1080

await this.page.setViewport({ width: 1280,height: 720,deviceScaleFactor: 1});

此大小需要与rrvideo的rrvideo.config配置文件相同

rrvideo.config

{

"width":1280,

"height":720,

"speed": 1,

"skipInactive": true,

"mouseTail": {

"strokeStyle": "green",

"lineWidth": 2

},

"startDelayTime": 1000

}

全方法

public async init() {

try {

this.browser = await puppeteer.launch({

headless: this.config.headless,

});

this.page = await this.browser.newPage();

// 增加设置超时时间为0

await this.page.setDefaultNavigationTimeout(0);

// 设置puppeteer打开谷歌浏览器的大小

await this.page.setViewport({ width: 1280,height: 720,deviceScaleFactor: 1});

await this.page.goto("about:blank");

await this.page.exposeFunction("onReplayStart", () => {

this.startRecording();

});

await this.page.exposeFunction("onReplayFinish", () => {

this.finishRecording();

});

const eventsPath = path.isAbsolute(this.config.input)

? this.config.input

: path.resolve(process.cwd(), this.config.input);

const events = JSON.parse(fs.readFileSync(eventsPath, "utf-8"));

await this.page.setContent(getHtml(events, this.config.rrwebPlayer));

} catch (error) {

this.config.cb("", error);

}

}

2.4.4、问题三：视频转换速度和清晰度问题

转换速度

// 在index.ts中的RRvideoConfig中，将fps由10改为15

const defaultConfig: RRvideoConfig = {

fps:15,

headless: true,

input: "",

cb: () => { },

output: "rrvideo-output.mp4",

rrwebPlayer: { },

};

清晰度

// 在index.ts中的startRecording方法，调整ffmpeg的配置

// 原

const args = [

// fps

"-framerate",

this.config.fps.toString(),

// input

"-f",

"image2pipe",

"-i",

"-",

// output

"-y",

this.config.output,

];

// 改为

args = [

// fps

"-framerate",

this.config.fps.toString(),

// input

"-f",

"image2pipe",

"-i",

"-",

// output

"-y",

"-b:v",

"2000k",

this.config.output,

];

ffmpeg配置含义参考：

https://zhuanlan.zhihu.com/p/145312133

https://wenku.baidu.com/view/45b9f4a51a5f312b3169a45177232f60dccce749.html?wkts=1701760052153&bdQuery=ffmpeg+%E5%8F%82%E6%95%B0%E9%85%8D%E7%BD%AE-s

2.4.5、更改index.ts如何在服务器上生效

本地修改完index.ts代码后，需要将其编译为js文件，上传到服务器中

上传路径：nodejs目录下安装的rrvideo下build文件夹

以测试环境为例：/opt/nodejs/node14.17.6/lib/node_modules/rrvideo/build/index.js

将本地反编译的文件替换上面目录的index.js即可

.ts转为js

ts文件是TypeScript (一种JavaScript的超集)文件，要将其编译成,js文件，你需要使用TypeScript编译器.以下是使用TypeScript编译器编译.ts文件的步骤:

1.安装TypeScript: 首先，确保你的系统上安装了Node.s。然后，在终端或命令提示符中运行以下命令今来全局安装TypeScript:

npm instal1 -g typescript

这将安装TypeScript编译器并在你的系统上设置一个类型化的命令tsc。

2.编译ts文件:在终端或命令提示符中，导航到包含ts文件的目录，并运行以下命今来编译.ts文件

tsc index.ts

2.4.6、rrvideo 录制弹窗展示不全，展示多个等问题

只要你使用rrWeb-player播放的内容和最终转换视频后的内容不一致，都是此问题导致

此问题的原因为rrvideo的版本没有人维护了，所使用的rrWeb-player版本很低，所以播放的时候有很多问题

找到你的rrvideo的位置，打开package.json查看rrWeb-player版本

cat /opt/nodejs/node14.17.6/lib/node_modules/rrvideo/package.json (你的rrvideo安装的地址)

{

"_from": "rrvideo",

"_id": "rrvideo@0.2.1",

"_inBundle": false,

"_integrity": "sha512-EumIkBkXq+C2Ki6MKXYH3bxik5kTnZWn1IO6YmdJrLXHqgoPla7XUib0HpITE8UevFMq8xufXuo0ElHdwD5AZQ==",

"_location": "/rrvideo",

"_phantomChildren": { },

"_requested": {

"type": "tag",

"registry": true,

"raw": "rrvideo",

"name": "rrvideo",

"escapedName": "rrvideo",

"rawSpec": "",

"saveSpec": null,

"fetchSpec": "latest"

},

"_requiredBy": [

"#USER"

],

"_resolved": "https://registry.npmjs.org/rrvideo/-/rrvideo-0.2.1.tgz",

"_shasum": "8849ead66853621884e21d3e254f33e18ca93378",

"_spec": "rrvideo",

"_where": "/opt/nodejs/node14.17.6/lib",

"author": {

},

"bin": {

"rrvideo": "build/cli.js"

},

"bundleDependencies": false,

"dependencies": {

"@types/minimist": "^1.2.1",

"@types/puppeteer": "^5.4.0",

"minimist": "^1.2.5",

"puppeteer": "^5.4.1",

"rrweb-player": "^0.6.5",

},

"deprecated": false,

"description": "transform rrweb session into video",

"name": "rrvideo",

"scripts": {

"build": "tsc",

"prepublish": "yarn build",

"test": "test"

},

"version": "0.2.1"

}

可以看到，rrvideo引用的rrWeb-player版本为0.6.5

修改此内容为你的rrWeb-player对应版本，我的是1.0.0-alpha.4

修改后执行

# 在/opt/nodejs/node14.17.6/lib/node_modules/rrvideo/下执行

npm install

# 若下载太慢，切换淘宝镜像(我太贴心了)

执行后重新转换视频，转换的视频和本地使用rrWeb-player播放的效果一致

吐槽：rrvideo好像很长时间没有人维护了，一堆问题，按照我的方式将它的代码优化后，基本使用时完全没有问题的。github上还有很多人的提问都没有回答，感觉是没人维护了，所以这些改动代码我没有提上去，大家有时间的可以将改好的代码提交上去，或者回答下github上的问题

2.5、rrvideo完整修改后代码

操作步骤

按照2.4.2、2.4.3、2.4.4、2.4.6更改下载的rrvideo源码中的index.ts按照2.4.5生成对应的index.js将生成的index.js替换服务器安装的rrvideo对应的index.js

rrvideo中index.js地址

#找到你安装的rrvideo地址

# 以下是我的地址

下面分享我修改好后的index.js，替换掉原rrvideo的即可，喜欢的可以点个收藏，谢谢~
