mkvtoolnix | Creating and working with Matroska files | Form library

So I am currently trying to make something that uses mkvmerge to merge audio, video and an unknown amount of subtitle files. For now, those subtitle filepaths are in a list.

Here is my issue. I cannot for the life of me think of a way of putting this into subprocess run, without throwing an error. If I combine the subtitle names into a single string, mkvmerge throws an error, so each file would need to be inside "","" themselves.

So, the command without subtitles looks like this:
subprocess.run(['C:\MKVToolNix\mkvmerge.exe', '-o', f'E:\Videos\{output_filename}.mkv', 'E:\Videos\viddec.mp4', 'E:\Videos\auddec.mp4']) So this will produce a working video.

AFAIK, a properly formatted subprocess call including two subtitles would need to look like this. subprocess.run(['C:\MKVToolNix\mkvmerge.exe', '-o', f'E:\Videos\{output_filename}.mkv', 'E:\Videos\viddec.mp4', 'E:\Videos\auddec.mp4', 'E:\Videos\eng.srt', 'E:\Videos\nor.srt'])

Is it possible to add variables like that, as individual strings into a subprocess.run call, so that it will function properly? or is there perhaps a different method/call I cannot think of?

I am attempting to batch edit metadata of some video files by piping the results from ls into a function that edits the video file's name in metadata. Example:

Files:

• My Movie 1 - 1080p DTS 5.1.mkv
• My Movie 2 - 720p DTS 2.1.mkv
• My Movie 3 - 480p AAC 1.0.mkv

Desired title renames in metadata:

• My Movie 1
• My Movie 2
• My Movie 3

I am using the mkvpropedit function from MKVToolNix in PowerShell, which can be used to rename a single file's title in the following way:

I need help on converting some codes as I am very new to mkvmerge, powershell and command prompt.

The CMD code is from https://github.com/Serede/mkvtoolnix-batch/blob/master/mkvtoolnix-batch.bat for %%f in (*.mkv) do %mkvmerge% @options.json -o "mkvmerge_out/%%f" "%%f"

What I've managed so far

Is it possible to use FINDSTR with a variable instead of a file?

I've tried researching this but my knowledge on batch isn't good enough yet.

I've made most of my batch file work flawlessly for what I need, but I'm having trouble extracting part of a string variable into a new variable.

The original variable for example would be S02E12 - Charge!. I would like to extract 02 to ep_seas, 12 to ep_num, and Charge! to ep_name. I have it working right now if that's the exact pattern of names, but I've come across some files that are in this pattern: S02E124 - Charge #2!

Is there a way I can dynamically get the values I need regardless of their length?

My idea was to use FINDSTR to search between the S and the E, then between E and space   (or -), then between - and the end. I'm not sure how I would proceed with this though.

Does anyone have a solution I can look into or can someone provide an example?

I`m editing a bunch of files with mkvmerge and I'm doing this:

Video from original-001.mkv mux with audio from audio-001.mkv and add subtitle from sub-001.mkv.

I'm creating a bunch of .bat scripts and using notapad++ find and replace function to do this:

find 001 and replace for 002, save as 002.bat and move on.

Basically, there will always be a base file named 001.bat

What would be really great is this Notepad++ portion could be automated. Find all strings "001", replace with "002", save as 002.bat Find "002", replace with "003", save as 003.bat.

Up to 300.

And finally what I do is another script: Call 001.bat Call 002.bat and so on. If I file doesn't exist there's no problem.

Is this possible using batch script on windows?

EDIT to add code as the way I'm going now: Example of 001.bat

Ok, I'm total new at this... Basically I'm using a tool call mkvmerge to attach multiple font files(.ttf) to .mkv files. I have separated the .mkv files into folders together with the respective fonts I would like to attach.

My aim is to create a batch that creates a copy of all the .mkv files with all the added attachments and deposits them in a newly created a folder (i.e Revised) in the parent directory.

Beginning with just a single folder:

I want to change tags of my all mkv files. I installed MKVToolNix. My code is:

I'm using ffmpeg 3.2.7 and I have a problem converting a ts-file lossless to mkv. The source file is a dumped IPTV-stream recorded with dumprtp (from dvbstream 0.5).

ffmpeg -i Test.ts -map 0:0 -map 0:2 -vcodec copy -acodec copy -f matroska Test.mkv

The convertion is successful, but the output file is pixelated every few seconds.

When I'm converting it with MKVToolnix everything looks fine.

Does anyone has a solution for that problem? Maybe some option to sync the stream correctly?

Here's a sample output:

I followed the instructions on https://kubernetes.io/docs/tasks/tools/install-kubectl/ on my Mac and installed Kubernetes CLI using brew.
