• I need assistance of making a automated script for ffmpeg [closed]

  18 décembre 2024, par user2614404

  Currently i use this script that GPT generated :

  


  ffmpeg -c:v av1_qsv -b:v 0 -global_quality 20 -preset veryslow -look_ahead 64 -c:a copy -c:s copy G:\1ARC-movies\A-View-to-a-kill.mkv -i Y:\media\Movies\A_VIEW_TO_A_KILL_t05.mkv

  


  But sadly GPT being gpt, it hallucinates answers, and none of it's deeper automation code scripts were working when it made the scripts for a .ps1 script file.

  


  And as i find most of the docs quite overwhelming, i need help to simplify what i need. As i learn best when i get explained what i currently try to do, and not every variable ffmpeg can do.

  


  what i want the script to do is :

  


  1 : convert movies with AV1_QSV with "veryslow", as that's apparently from what i've read up being the best it can do

  


  2 : Global quality as close to 50 as possible (smaller, the better), as 20-6 gave the same range of percentage of 97% VMAF score, 22 gave 95%, so 20 is the largest number i can go, as VMAF via NMKODER reported any higher number was sub 97%.

  


  3 : Give it a main folder for movies and shows to scan, and convert all the media in there to their respective subfolders to a designated output folder.

  


  2 : Automatic crop detection, as some crops it to a 21:9 ratio, others has very small letterboxes. As GPT's code for that attempt for some reason used cpu instead of arc's quicksync.

  


  As this will be ran from powershell, and it's to replace my plex library, by transcoding all movies and shows, starting with the least watched ones/shows that my family has seen, as then those will be unavailable for them until unraid 7 is out of beta to read intel arc for av1.

  


• How to improve this Powershell script ?

  3 janvier 2023, par Joan Venge

  I wrote a powershell script that merges go pro video files if they have multiple files. It works when the videos are at the root drive i.e. C :, but otherwise not. The mergevideos.txt file is not created if I run the script from a different directory. Or the txt is created but it's empty. Not sure what's going on when run from a different directory.

  


  So is there a way to fix these issues and refactor this code to make it better ? Ideally I want the script to automatically look at the directory it's in or allows me to specify the directory it should work in so I can just call it from the same location but the videos can be anywhere.

  


  $path = "C:/NewVideos/"
$oldvids = Get-ChildItem -Path $path *.mp4
foreach ($oldvid in $oldvids) {
    $curpath = $oldvid.DirectoryName

    $name = [System.IO.Path]::GetFileNameWithoutExtension($oldvid)
    $ext = [System.IO.Path]::GetExtension($oldvid)
    if ($name.StartsWith("GX01") -and !($name.EndsWith("_merged")))
    {
        $newvid = $curpath + $name + "_merged" + $ext
        if ([System.IO.File]::Exists($newvid))
        {
            Write-Output "$name | ALREADY MERGED"
            continue
        }

        $count = 1

        for ($num = 2; $num -lt 10; $num++)
        {
            $nextpart = $name.Replace("GX01", "GX0" + $num)
            if ([System.IO.File]::Exists($curpath + "/" + $nextpart + $ext))
            {
                $count = $num
            }
        }

        if ($count -eq 1)
        {
            Write-Output "$name | SINGLE VIDEO"
            continue
        }

        $mergefile = $curpath + "mergevideos.txt"
        if (!(Test-Path $mergefile))
        {
            New-Item -path $curpath -name mergevideos.txt -type "file"
        }

        Clear-Content $mergefile

        for ($num = 1; $num -le $count; $num++)
        {
            $nextpart = $name.Replace("GX01", "GX0" + $num)
            $videofilename = "file '" + $nextpart + $ext + "'"
            Add-Content $mergefile $videofilename
        }

         Write-Output "$name | MERGING  $count VIDEOS"
         ffmpeg -f concat -safe 0 -i $mergefile -c copy $newvid
    }
}
