Could you explain a little more?

If your input file is a transport stream (read from 
dvb) then it will (practically) always start with 
"errors" (because partial and/or nonkey-frames are 
sent to the decoder) but that neither makes the 
decoding fail nor is there anything (that makes 
sense) possible for you to avoid the errors.

Or do I misunderstand?

> ffmpeg -i INPUT -f mp4 -benchmark -y null

$ ffmpeg -i INPUT -f null -

will be (at least) a magnitude faster but as said 
please explain your usecase.
