FFmpeg: merge a folder of AVI files with names that include order number

You can merge a series of .avi files with ffmpeg using the concat filter. However, the concat filter requires that all inputs have the same streams (same codecs, same time base, etc.).

Create the text file using echo

First, create a file that contains the list of all your .avi files. You can do this manually, but if your files are named in a sequence like 01.avi, 02.avi, 03.avi, and so on, you can generate this list automatically using a bash command. Here's how you can do it:
