How to compile mkv via linux console?

Question

linux

You need to collect the matryoshka mkv file through the console. There are two video and audio files, they need to be collected through the console into one mkv container. Googling only gives GUI build instructions, which doesn't work for me.

How to compile through the console like this: file.aac + file.avi = file.mkv

Answer 1

Without conversion - like this:

ffmpeg -i file.avi -i file.aac -vcodec copy -acodec copy file.mkv

This is provided that there is no audio track in the avi. If it is, then you will also need to add -map.
