help with using GST_TRACER

Hi Stefan,

Thanks for pointing me to the existing documentation during the conference

Yes I run gst-stats after running a pipe with GST_TRACERS="stats;rusage" and
that shows cpu usage and some buffer information.
I'm not very interested in the cpu load, so for me it is not a problem if it
isn't always right.

What I really want is the latency information (the individual processing
time of each element).
And it think it could be nice if that could be parsed by gst-stats to show
latency information like fx. the buffer size information is shown.

The only thing I can get right now is the time from src element to sink
element when setting GST_TRACERS=latency.

I'm running 1.8.0 so I might not be up to date with new features.

Is it possible to get the information I want at the moment or is there any
interest/plan to add such functionality?

Thanks

Marianna
