Hi,
I ran a gstreamer pipleline using gst-launch and captured profiling data
using oprofile.
In the profile report it is seen that gst_clock_id_compare_func is consuming
a lot of cpu samples .
Is there any way we can reduce the cpu usage by function
gst_clock_id_compare_func by tweaking some gst clock parameters ?

samples  %        image name               app name                 symbol
