[FFmpeg-user] cpu

[focus television]

Him,
I am playing an mp4 file.


ffmpeg -i king.avi -profile:v baseline -level 30 \
-c:v libx264 -b:v 512k -s 640x360 -r 25 \
-c:a libfaac -b:a 64k -ar 44100  \
-f:v flv \
rtmp://localhost/live/teststream
and it is showing 100% usage
I see that in vlc it is show h264 and mpga audio . But still it accepts 
the encoding and uses lot of cpu.
It i take out the codec or put copy it gives error in header...
ANy idea where i am wrong?
