Checking other reports it seems that pthread might need -latomic
Is this using 32-bit raspbian? I'd hope this wouldn't happen on a less horribly outdated OS, atomics via function calls is really, really bad for performance. 
Note that you can also compile MPlayer against your installed FFmpeg instead of the internal copy.

Yes it is a 32 bit Raspbian(now Rapberry Pi OS).  I can try with -atomic option in running 
$ ../configure -iatomic
then run make 
and it may work?
and if it does not how can I enable ffmpeg-4.3.1 built from source?
Thank you for your help.
Best Regards,

Antonio
