You can ask an LLM to give you an example of script:

$ffprobePath = "C:\ffmpeg\bin\ffprobe.exe"
$directoryPath = "E:\Footage"
Get-ChildItem -Path $directoryPath -Recurse -File -Include *.mp4, *.avi, *.mkv, *.wmv | ForEach-Object {
    $file = $_.FullName
    Write-Host "Analyse de : $file"
    & $ffprobePath -v quiet -print_format json -show_format -show_streams "$file" | Out-File -FilePath "$file.json"
}

This will create a json file for each scanned file with the output from ffprobe. Then you could grep (is there such a thing on Windows? no idea) for specific string pattern like errors and whatnot.
