[FFmpeg-user] Synchronize videos

I have a number of devices. Each with a camera attached. Video from each 
camera is captured to a file. Audio is only captured from one of the 
cameras. Capture is done using ffmpeg.

Once I am done capturing data from the cameras I process the files, 
again using ffmpeg. I create a single video where video from each camera 
is shown at the same time.

My question is how can I make sure that the videos are synced correctly. 
I am not able to start capturing at the same time, so I can not be sure 
that the videos from each camera cover exactly the same period.

Any hints would be very much appreciated.
