If the codecs are the same, you can do the following.
First, create a text file with each line describing the files to be
combined like this;
Next, execute the following command in the same directory as this text
$ ffmpeg -f concat -i mylist.txt -c copy output.mp4
If you want to combine videos with different codecs, either remove -c
copy (the default codec is used) or specify the codec to encode.
