• Failed to find two consecutive MPEG audio frames [closed]

  3 décembre 2024, par matrixebiz

  I'm receiving this error trying to download/convert an m3u8

  


  [mp3 @ 000001c8f5112200] Format mp3 detected only with low score of 1, misdetection possible!
[mp3 @ 000001c8f5112200] Failed to find two consecutive MPEG audio frames.
[in#0 @ 000001c8f5111f40] Error opening input: Invalid data found when processing input


  


  Any way to fix this in my ffmpeg command line ? Also, playing the stream in VLC and other apps shows this in the path /%EF%BB%BF for some reason.
VLC is unable to open the MRL 'file :///C :/Temp/%EF%BB%BF'. Check the log for details. Then it will play the actual video.

  


  Do i need to change the beginning of the m3u8 ?
#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1000,RESOLUTION=640x360,

  


  Even if I remove it and just leave the URL that is inside the m3u8, will still display the %EF%BB%BF which I need to stop from happening

  


  EDIT : Adding the PowerShell script I'm using to output my file :

  


  function Replace-FileText
{
    [CmdletBinding()]
    Param
    (
        $File1,
        $File2,
        $File1StartAnchor,
        $File1EndAnchor = "$",
        $File2StartAnchor,
        $File2EndAnchor = "$"
    )
    
    #Escape the regex meta characters, this assumes literals are used in the input
    $File1StartAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File1StartAnchor)
    $File2StartAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File2StartAnchor)

    if ($PSBoundParameters.ContainsKey('File1EndAnchor'))
    {
        $File1EndAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File1EndAnchor)
    }
    else
    {
        $File1EndAnchorEscaped = $File1EndAnchor
    }

    if ($PSBoundParameters.ContainsKey('File2EndAnchor'))
    {
        $File2EndAnchorEscaped = [System.Text.RegularExpressions.Regex]::Escape($File2EndAnchor)
    }
    else
    {
        $File2EndAnchorEscaped = $File2EndAnchor
    }


    if ((Get-Content $File1 -Raw) -match "$File1StartAnchorEscaped(.*?)$File1EndAnchorEscaped")
    {
        Write-Host "Found the following string in between the anchors in $File1 :$($Matches[1])"
        $TextToInject = $Matches[1]
    }
    else
    {
        Write-Host "Could not find the Start and end Anchors in $File1"
        return
    }
 
    if ((Get-Content $File2 -Raw) -match "$File2StartAnchorEscaped(.*?)$File2EndAnchorEscaped")
    {
        Write-Host "Found the following string in between the anchors in $File2 :$($Matches[1])"
        $TextToReplace = $Matches[1]
    }
    else
    {
        Write-Host "Could not find the Start Anchor in $File2"
        return
    }
 
    (Get-Content $File2 -Raw) -replace $TextToReplace,$TextToInject | Out-File $File2 -NoNewline
}

• Unable to find correct bash syntax for comparing numbers

  17 octobre 2024, par kali

  Part of a long script I'm simply trying to compare two numbers, one is constant and the other one is retrieved via ffprobe (The 474 in the error messages is the height found by ffprobe)

  


  CURRENT_RES=$(ffprobe -v quiet -select_streams v:0 -show_entries stream=height -of csv=s=x:p=0 "${fn}")
  if [[ $CURRENT_RES -gt 1080 ]]; then
    echo "leaving preset normal"
    SLOW_PRESET=("" "")
  else
    echo "setting preset to slow"
    SLOW_PRESET=(-preset slow)
  fi;


  


  produces :

  


  /usr/local/bin/startScreen.sh: line 95: [[: 474

474: syntax error in expression (error token is "474")
setting preset to slow


  


  I also tried arithmetic operators like :

  


    if (($CURRENT_RES>1080)); then
    echo "leaving preset normal"
    SLOW_PRESET=("" "")
  else
    echo "setting preset to slow"
    SLOW_PRESET=(-preset slow)
  fi;


  


  got a slightly different, but essentially same error message like :

  


  /usr/local/bin/startScreen.sh: line 95: ((: 474

474>1080: syntax error in expression (error token is "474>1080")
setting preset to slow


  


  What's even more baffling is there 15 lines below this block there is another comparison which works perfectly fine !

  


  if [[ $CURRENT_RES -gt $CONVERT_HEIGHT ]]; then


  


  I thought may be the inline written 1080 number is confusing the if expression so I tried assigning 1080 to variable and reusing it, which changed nothing.

  


  edit : (dropping this here in case someone else falls into same mistake)
following up on Shawn's advice from comments using cat -v showed 474 was repeated twice.
For debugging purposes ran :

  


  ffprobe -v quiet -select_streams v:0 -show_entries stream=height -of json "filename.mp4"


  


  to find this weird format :

  


  {
    "programs": [
        {
            "streams": [
                {
                    "height": 472
                }
            ]
        }
    ],
    "streams": [
        {
            "height": 472
        }
    ]
}


  


  finally changed the ffprobe command to :

  


  CURRENT_RES=$(ffprobe -v quiet -select_streams v:0 -show_entries stream=height -of json "${fn}" | jq .streams[0].height)


  


  to resolve the issue.

  Error i got after run the code

  


  = RESTART: D:\Bots\2vidpod.py&#xA;Traceback (most recent call last):&#xA;  File "D:\Bots\2vidpod.py", line 71, in <module>&#xA;    os.remove(os.path.join(output_folder, &#x27;temp.mp4&#x27;))&#xA;FileNotFoundError: [WinError 2] Не удается найти указанный файл: &#x27;D:\\bots\\ttvidads\\VID\\ZAGOTOVKI\\Videopod1\\temp.mp4&#x27;&#xA;</module>

  


  so things i checked is
path is right
programs is installed FFMPEG and PYTHON all additional libraries downloaded
i pretty sure error caused by regular path and i wanna know if absolute path can do the thing
