Joining video files with ffmpeg

Using ffmpeg from the command line is by far the most efficient way to join common video formats. Note that this method does not re-encode the video (which would cause unavoidable loss of resolution and add artifacts).

ffmpeg  -loglevel info -f concat -safe 0  -i files.ffmpeg -c copy   newfile.mkv

Then, make sure to have the full path to the files in the files.ffmpeg text file.

file '/home/rwxrob/somefile1.mkv'
file '/home/rwxrob/somefile2.mkv'
file '/home/rwxrob/somefile3.mkv'

Eventually, I need to put this into a script.
