And that is not the _latest_ ffmpeg (forget about "for centos", it's not).

All of these errors say the basically the same thing, the file is well-damaged-

If you google for "moov atom not found", you'll find a pile of suggestions 
and pointers to some tools. At this point, that will probably help more than 
poking about with ffmpeg options.

For future recordings, consider using a different output container like flv 
or ts (or mkv?); those are more resilient to streaming errors.
