I''m trying to mux many subtitle languages into the same file (MKV as output) but it's not working. I'm trying the following from a batch file:
FOR /R %%A IN (*.mp4 *.webm) DO mkvmerge -o "%%~nA.mkv" "%%~A" --language 0:eng "%%~nA.en.srt" --language 1:spa "%%~nA.es.srt" --language 2:ger "%%~nA.de.srt" --language 3:por "%%~nA.pt.srt"
What am I doing wrong?
I get the following result: Error: The file 'video1.en.srt' could not be opened for reading: open file error.
It's reading all the files correctly, but it won't process the command.
