I have several video files in a directory and I want to convert all of them into other video formats.
Is there any way that I can convert all of them in just one go using FFMPEG. I mean without having to make a shell script for doing so.

What about a simple for loop? for i in *.mkv;do ffmpeg -i "$i" …;done – Marco Jul 22 '12 at 15:14

The easiest way would be to use a for loop of your shell of choice. This task is so simple, you can just use the prompt, there's no need to create a shell script.

Here is the one-liner as an example for the widely-used bash (and compatible):

for i in *.mkv; do ffmpeg -i "$i" … ;done

Thanks, that's what I did. – Hamed Momeni Jul 22 '12 at 18:04

I just did such a conversion starting from Marco's solution. I added changing the file extension, in my case, from .mp4 to .mp3:

for i in *.mp4; do ffmpeg -i "$i" -codec:a mp3 "mp3/${i%.mp4}.mp3";done
