Allows to specify the action to be performed when reading the last frame
from the internal FIFO buffer. By default the last frame is written to
filter output depending on the timestamp rounding method. When using
"pass" action the last frame is passed through if input duration
has not been reached yet.

Examples using an input file with 25Hz, 1.4sec duration:
 - "fps=fps=1:round=near" generates an output file of 1sec
 - "fps=fps=1:round=near:eof_action=pass" generates an output file of
   2sec
