Pipeline profiling.

[Baby Octopus]

You can see if this CPU profiling tool would help -

On the contrary, I'm not sure what exact profiling you would want to do for
omx encoder. For the hardware encoding, the gst wrapper might have to use
very little CPU and may show negligible percentage

If you want to see what percentage of GPU is busy, I'm not really sure if
its even achievable :)  A crude method would be to run the pipeline in
non-live mode(as fast as possible) and see what FPS you are getting as
output to know the real horsepower of hardware encoder
