[FFmpeg-user] FFmpeg manual - asking for clarification of a definition

[ILJA SHEBALIN]

FFmpeg manual - Main options;

-t duration (*input/output*)

When used as an input option (before -i), limit the duration of data read
from the input file.


I have a hard time understanding what the formulation was supposed to
denote. Is the option limiting the data to the *duration *or is the data
that's out of the scope of the *duration *is read?
