 I am taking an RTP stream and adding loudnorm and rebroadcasting it.
 ffmpeg will use the cpu more and more over time. See this graph:
 http://puu.sh/qeg9W/8529b8a5b5.png (over a time span of 3 hours).


 When I took out the loudnorm filter, it seems to not be increasing slowly
 over time, or just a lot less. I need more time to verify it's not going
 up anymore. If it is, it's a lot slower and a lot less dramatic.

 My command:

 ExecStart=/root/bin/ffmpeg -loglevel panic -i rtp://127.0.0.1:5001 -c:a
 libmp3lame -af loudnorm=I=-15 -f tee -map 0:a
 "[f=rtp]rtp://224.3.3.3:1235|[f=mpegts]udp://192.168.0.113:1235/"

 (repeats, works fine except for my cpu usage problem)
