我正在尝试使用 powershell 和 rtmpdump 监控直播电视频道 rtmp 提要。我要监视的流保存在遵循 csv 格式的“streams.txt”文件中。

Name,feed,file
tv1,rtmp://server/live/tv1,tv1.flv
tv2,rtmp://server/live/tv1,tv2.flv
tv3,rtmp://server/live/tv1,tv3.flv 
tv4,rtmp://server/live/tv1,tv4.flv

在导入 csv 文件并转换对象中的数据后，我遍历每个对象并使用 feed 属性，一旦此过程正常工作，我就会启动 rmtpdump 命令，其余的 powershell 将停止。

为了解决这个问题，我尝试使用计时器，但是当 rtmpdump 捕获循环内的第一个提要时，即使它们也没有解决我的问题。

Register-ObjectEvent -InputObject $timer -EventName elapsed –SourceIdentifier  thetimer -Action $action 



$colStats = Import-CSV streams.txt
foreach ($objBatter in $colStats)
  {
    $timer.start()
    $objBatter.feed  + "," + $objBatter.file
    .\rtmpdump.exe -r $objBatter.feed -o $objBatter.file

  }



#to stop run 
$timer.stop() 
#cleanup 
Unregister-Event thetimer

#loop through flv files and all 0 bytes files are faulty channel

#deleting files with 0 size
#dir | ? {$_.length -eq 0} | del

我需要捕获 30 秒播放的提要输出，然后终止 rtmpdump 进程，在循环的下一次迭代中，我想捕获 30 秒的第二个提要。

如果一个流不起作用，它将生成 0 字节的 flv 文件，我稍后会发送通知

我相信这可以满足您的需求...它将遍历 csv 文件，运行 rempdump 过程 30 秒，将其杀死，然后转到下一个提要。

#Import the streams
$colStats = Import-CSV streams.txt

#Loop through the streams
foreach ($objBatter in $colStats)
{
    $Process = ".\rtmpdump.exe"
    $arguments = "-r $objBatter.feed -o $objBatter.file"

    #Launch Process
    $Ps = Start-Process -FilePath $Process -ArgumentList $Arguments -PassThru

    #Wait 30 seconds
    Sleep -Seconds 30

    #Kill the process
    $Ps.Kill()
}

#loop through flv files and all 0 bytes files are faulty channel

#deleting files with 0 size
#dir | ? {$_.length -eq 0} | del
