  • Have an error running one PowerShell script to concatenate avi files, when a very similar script works fine

    1er juillet 2023, par hw22s

    When I run the following PowerShell script, to concatenate the .avi files in a folder, I get an error.

    


    Script :

    


    # Set the folder path where the AVI files are located
$folderPath = "C:\Users\HomePC\hswlab\Desktop\videos\eyeblink\022223\2023_04_24\16_15_23\My_WebCam"

# Get all AVI files in the folder
$aviFiles = Get-ChildItem -Path $folderPath -Filter "*.avi" | Sort-Object Name

# Check if there are at least 2 AVI files for concatenation
if ($aviFiles.Count -ge 2) {
    $videoFiles = $aviFiles.FullName

    Write-Host "Input Files for Concatenation:"
    foreach ($file in $aviFiles) {
        Write-Host $file.Name
    }

    $outputFile = Join-Path -Path $folderPath -ChildPath "concatenated.avi"

    # Create the FFmpeg command for concatenation
    $concatArguments = "-f", "concat", "-i", "`"concat:$videoFiles`"", "-c", "copy", "`"$outputFile`""

    $command = "ffmpeg $concatArguments"
    Write-Host "FFmpeg Command: $command"

    try {
        $process = Start-Process -FilePath "ffmpeg" -ArgumentList $concatArguments -NoNewWindow -PassThru -Wait -ErrorAction Stop
        Write-Host "Concatenation complete. Output file: $outputFile"
    } catch {
        Write-Host "Error occurred while executing FFmpeg command:"
        Write-Host "Error message: $($_.Exception.Message)"
    }
} else {
    Write-Host "Not enough AVI files found in the folder for concatenation."
}


    


    Output with error, (and no concatenated file is actually produced, needless to say) :

    I can't figure out what is wrong with the first script. I tried many variations of the first script but cannot get it to work.

    


    Any help ?
