Too old

Your version is way too old, and in fact I don't think it even supports any filters if I recall correctly. You can check with ffmpeg -filters.

Get a new ffmpeg

To get a recent version you can compile ffmpeg or simply download a static build. Users of Ubuntu 15.04 or newer can just install ffmpeg from the repository.

Example command

This example will:

1. Place video1.mp4 20 pixels down and 40 pixels over.


2. Place video2.mp4 in the middle.



3. Combine audio from video1.mp4 and video2.mp4.

   
   
   

   ffmpeg -i bg.mp4 -i video1.mp4 -i video2.mp4 -filter_complex 
   
   "[0:v][1:v]setpts=PTS-STARTPTS,overlay=20:40[bg]; 
   
    [bg][2:v]setpts=PTS-STARTPTS,overlay=(W-w)/2:(H-h)/2[v]; 
   
    [1:a][2:a]amerge=inputs=2[a]" 
   
   -map "[v]" -map "[a]" -ac 2 output.mp4
