rethink log format. current format:
* is not easy to parse/process by commandline tools
* cannot be easily diffed (timestamps, pid)

gst_debug_log_default() is default gst-log handler.
try new via:
  gst_debug_remove_log_function(gst_debug_log_default)
  gst_debug_add_log_function(func,data)

== reorder fields ==

format of default handler is:
                 DEBUG (0x8134bc0 - 0:00:00.848191000)              GST_QOS( 3340) gstbasesink.c(1431):gst_base_sink_do_render_stats:<xvimagesink0> avg_render: 0:00:00.009044000

something like:
  cut -c35- | sed -e "s/0x[0-9a-f]\{7,8\}//g"
should make logs easily 'diffable'.

== color code level ==

I suggedt to color-code loglevels if COLOR is allowed:
ERROR   : red
WARNING : yellow
INFO    : green
DEBUG   : turkis
LOG     : gray
NONE    : gray

== log sources ==

What about differentating between log sources:
  core
  elements
  application
