Windows script to remove non [insert your preferred languages] tracks

[ginjaninja 533]

Removes eg. Audio and Subtitle Tracks from selected (in Explorer) MKVs which do not match your preferred language(s)

ignores files which do not contain at least 1 audio track with any one of your preferred languages

ignores files which do not contain  audio tracks other than your preferred languages

instances a wait state to prevent multiple mkvmerges running at same time to prevent a disk bottleneck (not spindle aware)

Halts processing if Mkvmerge errors or temp processing file not found. (to protect deleting original file if an issue)

Test with extreme caution. This script deletes processed files

 

Installation

copy script/reg to filesystem.

set your preferred languages in the script

Edit .reg with path to your script and run .reg to import.

Right-click one or more mkvs and choose "KeepLanguage".

Changes

v0.0.0.7 corrects some behaviour when path contains special characters

Keeplanguage v0.0.0.7.zip

Use with extreme caution. If the MKV does not contain tracks of your language you will end up with no tracks.

tested on MKVMerge v63

*Removes the dust*

Script needs adaption, need to replace pwsh.exe with powershell.exe (Win10 64-bit)

And I need some help, if possible, I get the following output, after I changed lines #6 and #7

#mylanguages=@("ger")
$mylanguages = @("ger")

if you can pm a link to a test file i can check.

you can install pwsh https://github.com/PowerShell/PowerShell/releases/download/v7.3.1/PowerShell-7.3.1-win-x64.msi

cant be sure if anything in the script needs pwsh  or not...

 

 

[Eigeplackter 75]

Even with pwsh same result for me.

You got PM with link

posted v0.0.0.7 a bug fix for special characters in path.

[Eigeplackter 75]

No good news from my front, but thanks anyways.

Just discovered your script and I am happy, it is much faster via Powershell than my old .bat file. Thank you!

I have 2 concerns/questions. Can you add a variable so that the subtitles can be separated from the main language?

#1

So audio e.g. "ger

Subtitle "ger" & "eng" 

#2

Is it also possible to right-click on a series folder and the script then dedicates itself to all MKVs in this folder? That way you don't have to select individual MKVs.

Is there actually a log?

Thank you very much!!!

#1 happy to help you edit the functionality of the script, am guessing if you can write batch you can follow google and write powershell?

to get you started

$mylanguages = @("eng")

$myaudiotracks = $audiotracks | Where-Object { $_.properties.language -in $mylanguages }
$mysubtitletracks = $subtitletracks | Where-Object { $_.properties.language -in $mylanguages }

$mylanguages = ($mylanguages -join ", ")

modify to

$mylanguages = @("eng")
$mysubtitlelanguages=@("eng","ger")

$myaudiotracks = $audiotracks | Where-Object { $_.properties.language -in $mylanguages }
$mysubtitletracks = $subtitletracks | Where-Object { $_.properties.language -in $mysubtitlelanguages }

$mylanguages = ($mylanguages -join ", ")
$mysubtitlelanguages = ($mysubtitlelanguages -join ", ")

the challenge might be what logic you drive from establishing these variables...probably going to involve tweaking the main condition to suit.

if (($myaudiotracks.count -ge 1 -and $myaudiotracks.count -lt $audiotracks.count) -or ($mysubtitletracks.count -ge 1 -and $mysubtitletracks.count -lt $subtitletracks.count -and $subtitleforce)) {

#2

tweaking the script to operate on a folder is not trivial

the registry file will need to be tweaked to associate the shell command to a folder and the script will need to implement some logic to determine if the passed argument is a file or a folder (unless you maintain a separate folder and file script). and 'if folder' enumerate (see get-item/get-childitem) the contents and act. Alot of busy work / google searching wouldnt attempt this until after #1.

theres no log...

 

give it a go and pm me if you need help.

[Seger 110]

I will take on the topic tomorrow and try to implement and test the first step, toi toi toi.
