[FFmpeg-user] Compilation Video

[Fred Kemp]

I am trying to automatically create a compilation video made up of 
security cam motion videos of relatively short duration (5 to 10 
seconds) - kind of like a time-lapse only with videos instead of images.

Each video snippet would append to the same compilation video file.  The 
compilation video would be limited to X minutes long and newer videos 
would knock off the oldest videos from the compilation video once the X 
is reached.

Can this be done using FFmpeg?

Thank you in advance for your consideration.
