  • 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"

        Write-Host "Error message: $($_.Exception.Message)"
    }
} else {
    Write-Host "Not enough AVI files found in the folder for concatenation."
}

  • Invalid frame dimension, invalid data found when processing input, muxing overhead : unknown when concatting old VOB files | FFMPEG

    9 mars 2023, par Victor Hartman

    I am dealing with multiple errors which I am not able to resolve. I am trying to concat 4 old VOB files to a mp4. Using command (already solved a 'pts has no value error') :

    


    .\ffmpeg.exe -fflags +genpts -f concat -i .\files.txt -c copy output.mp4


    


    files.txt looks like this :

file 'VTS_01_2.VOB'
file 'VTS_01_3.VOB'
file 'VTS_01_4.VOB'


    


    Output looks like this :
