How to check automatically and customizable via Shell / Programming Language integrity (Incomplete / Corrupted ) of video files ( .avi , .mp4 , .mkv among others)?
OBS: Having as a limiting factor the lack of a previous HASH of the files.
Given that there is no previous HASH (when you were sure of the file state) you need to use a Third Party program FFMPEG and a script executed via Powershell that automates the execution of checking the video files of a certain folder:
Script:
$logPath = "C:\Users\User\projeto1\error.log"
$videosFolder = "C:\Users\User\videos"
$ffmpegPath = "C:\ffmpeg\bin\ffmpeg.exe"
$arquivos = Get-ChildItem -path $videosFolder |
Where-Object {
($_.extension -eq ".mp4" -or $_.extension -eq ".mkv")
}
foreach($item in $arquivos){
"+#+#+ " + $item.FullName >> $logPath
&$ffmpegPath -v error -i $item.FullName -f null 2 >> $logPath 2>&1
}
FFMPEG executable is and where the LOG file will be created with the errors of each video .mp4 and .mkv ) FFMPEG passing some control parameters like how verbose the verification should be. Notes:
Verification is frame by frame as soon as errors are per frame.
It was organized so that the errors printed below the file name. (there may be no error, or there may be several errors in each frame which generates a huge Log file).
- NEVER allow errors to be displayed in standard output, always leave them to be stored in the Log file.
I've added a different + # + # + string at the beginning of each file path to make the search easier.
