First, create a text file with each line describing the files to be combined like this; mylist.txt file /path/to/fileA.mp4 file /path/to/fileB.mp4 Next, execute the following command in the same directory as this text file. $ 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.
