Now to do the part I have no idea about, which is to write a bash script. map 0:a:1 would specify only to copy audio stream number 1, while -map 0:a? should effectively wildcard it and copy them all. I'm still getting to grips with ffmpeg myself, but the map command is used to tell it that you definitely want those things to be pulled through to the output. 4 years, 11 months agoYes, give that a shot.

Would it look like this then? ffmpeg -i '01.mkv' -map 0:a? -map 0:s? -map 0:v -c:v copy -c:a ac3 -c:s copy 'test.mkv' 4 years, 11 months ago Look at the answers here if you haven’t already. I read about it, but I couldn't quite understand how to use it.

I suspect you need a -map 0:a? -map 0:s? -map 0:v before your -c:v, but apart from that it looks okay to me.
