gst-tracelib usage

[mingqian Han]

Hi all,
    I am now trying to use gst-tracelib to profile gstreamer performance on TI Dm365.
    After several trials, it works.
    But I meet a problem with the log.
    When I use ./gsttl_splitlog.py gsttl.log, it fails, saying :
    AttributeError: 'str' object has no attribute 'partition'
    
    my log file looks like:

    Besides,  I need help on interpreting the statistics.
     For example,
Pad Statistics:

      What do these different columns mean?

Thanks in advance.
