If video.mp4 already contains the correct codecs with the correct
parameters for your streamed mpegts, you could avoid recoding totally
by adding:
-c copy
(or -c:v copy, if it shall only apply to video).

That avoids very much of the CPU usage.


Apart from that, we usually expect your full ffmpeg command line and
the complete, uncut output on this list, to better understand your
scenario.
