MKV subtitle extraction and packaging software

Some netizens asked whether this software can separate audio files separated from VOB into AC3, DTS and PCM audio stream files (this audio file contains three tracks of AC3, DTS and PCM). My answer is: Yes, it can be video and audio in almost any format. In fact, what you separate using this software is what you want. The specific method is as follows:
1). First use MKVtoolnix(CN)-2.9.9 or 3.2.0 or 3.3.0 or 3.4.0 or 4.0.0 or 4.1.1 to make the file into an MKV file.
2). Then use MKVtoolnix(CN)-1.6.4.1 to extract the files you want.
Note: The file to be separated first must have more than one track.
