CPU load when streaming full HD camera input to full HD HDMI display

Hi all,

Now i am trying to stream a full HD resolution (1920x1080, 30fps) camera input from OV5640 MIPI camera to display it on a full HD HDMI display.

I manage to do so by:

gst-launch mfw_v4lsrc device=/dev/video1 capture-mode=5 ! mfw_v4lsink


However, when i see the CPU load using the 'top' command, the CPU load is near to 100%. Why is the CPU load so high? Isn't it the IPU should kick in in such situation and free the CPU from doing other task?


I am using i.mx6SabreSD board, trying to simulate performance of i.mx6 SOLO by limiting the cpu to 1 core in u-boot boot arguement.


Thank you.
