Do have a look at the documentation:
https://www.ffmpeg.org/ffmpeg-protocols.html#udp

I haven't tried, but it sounds like the "timeout" option is made for
you:

  ‘timeout=microseconds’

      Set raise error timeout, expressed in microseconds.

      This option is only relevant in read mode: if no data arrived in
      more than this time interval, raise error.

Cheers,
Moritz
