Use the draw parameter.

ffplay -f lavfi -i testsrc=n=2 -vf "drawtext=fontsize=25:fontfile=FreeSerif.ttf:x=100:y=x/dar:draw=lt(t\,5):text='hello world'"

Some few multimedia formats (mpeg-1, mpeg-2:PS, DV) support physical merge 
consistency, which means you can merge two files with cat. E.g.:
cat input1.mpeg input2.mpeg > output.mpeg
