rethink log format. current format:
* is not easy to parse/process by commandline tools
* cannnot 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

new proposed format:

something like:
sed -e "s/([0-9xa-f:. -]*) / /" -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
