how to set debug log format of gstreamer

[Soho Soho123]

Hi all,

I try to debug the issue :
gst-launch-0.10 --gst-debug-no-color --gst-debug-level=5 filesrc
location=/var/tmp/usb/sda1/audio_src/1503-9_48K.wav ! wavparse !
audioconvert ! audio/x-raw-int,
rate=48000,channels=2,width=16,endianness=1234 ! alsasink
device="hw:0,0"

I set debug level=5,
but there is a lot of log about typefind, for example below:
gsttypefindhelper.c:437:buf_helper_find_peek:<wavparse0>
'video/mpeg-elementary' called peek (7676, 4096)

how to remove typefind log?

And  how to remove the prefix data like"0:28:13.490000000  1045   0x423520"?

0:28:13.490000000  1045   0x423520 LOG  default
gsttypefindhelper.c:437:buf_helper_find_pe
ek:<wavparse0> 'video/mpeg-elementary' called peek (7676, 4096)
