Automatic Same Name

[jay123210599]

When doing any operation in ffmpeg, how do I automatically make the output file have the same name as the input file?

For example, I remux a single mkv file to mp4, and I want the output mp4 to have the same name as the input mkv.

Using a script is not allowed.

What OS?
Isn't anything called in a bash (on Windows) or a terminal (Linux/Mac) basically a script?
if you know the name and can use a environment variable probably do something like:
set p=INPUT_NAME && call ffmpeg -i "YOUR_PATH_TO/%p%.mkv" "OUTPUT_PATH/%p%.mkv"
(INPUT_NAME, YOUR_PATH_TO and OUTPUT_PATH are variables that need to be set)

I'm in Windows, and I don't want to use scripts. This is for cases like ffmpeg.

no.
:)

I think the only case where FFmpeg will parse formatted filename is with image2 muxer/demuxer

Is the OP wanting some kind of ffmpeg GUI ?
(requirement seems a little 'fuzzy')

You could try AnotherGUI. https://www.videohelp.com/software/AnotherGUI

Use the Executables menu to tell AnotherGUI where ffmpeg is.
A preset for remuxing a file as an MP4 might look like this (added to the First Pass section of the preset configuration), but of course it can be a preset for performing any type of ffmpeg conversion.

-i "<FullSourceFileName>" -y -threads 1 -vcodec copy -acodec copy "<OutputPath><OutputFileName>.mp4"

Once you've created the preset, select it and drag and drop a file or files onto AnotherGUI (any file type that can be remuxed as an MP4), then click "Go". The default output name is the same as the input.

I don't want a GUI. I want to put in something that will get me the same name for the output from the input, like %d or something.

If you don't want GUI's or scripts you can run that command line in a folder with the mkv's you want convert to mp4:

FOR %I in (*.mkv) DO "YOUR_PATH_TO\ffmpeg.exe" -i "%I" "%~nI.mp4"

What if I have only a single mkv I want to convert to mp4?

It will work for a single file.
