Hi,
Am using ffmpeg 1.1.4 for streaming .
Processor Model: TI-DM8148 Davinci processor .
ARM 7 with 600MHz speed
Linux 2.6.32 kernel
For ffmpeg live streaming through video port am using the following command
ffmpeg -s 720x576 -f v4l2 -pix_fmt rgb24 -i /dev/video0 -target
pal-vcd -vcodec mpeg4 -f mpegts -q 2 -s 360x288 udp:10.5.20.144:1234
With the above command if i check my CPU usage it shows 99% . By giving
'top' command am checking the CPU usage .
Any one suggest how to reduce the CPU usage .
Regards,
Subeesh

a.. It takes 99% of CPU usage . Any one suggest how to reduce my
CPU usage .
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.
