I am using following gstreamer for camera streaming on a IMX53 based custom board(kernel 2.6.35). When we start gstreamer it is taking 40% CPU. gstreamer version is 0.10.36.
#gst-launch mfw_v4lsrc device=/dev/video0 ! mfw_v4lsink
I thought of debugging the issue using oprofile, I have copied vmlinux to filesystem and started oprofile but it is giving following error.
The specified file /home/vmlinux does not seem to be valid Make sure you are using the non-compressed image file (e.g. vmlinux not vmlinuz)
I have copied vmlinux file only to filesystem.
Can you help to debug the gstreamer CPU utilization further.
