# first problem:

$ gst-launch-0.10  --quiet videotestsrc ! fakesink
New clock: GstSystemClock

# the new clock message isnt an error message, right? so it should not be
# printed with --quiet

# second problem:

$ gst-launch-0.10   videotestsrc ! fakesink >/dev/null

$ gst-launch-0.10   videotestsrc ! fakesink 2>/dev/null

# so all debug/progress messages are printed to stdout, not stderr as is the
# case with most other command line tools. this, combined with the first 
# problem, makes is unnecessary tricky to use fdsink to send data to another 
# program with a simple shell pipe without getting gst-launch messages mixed in
# with the data

# also,
# its one thing if status/debug messages are printed to stdout, but even some
# error messages are. but only some:

$ gst-launch-0.10 -q  videotestsrc ! filesink 
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstFileSink:filesink0: No file name
specified for writing.
Additional debug info:
gstfilesink.c(424): gst_file_sink_open_file ():
/GstPipeline:pipeline0/GstFileSink:filesink0

$ gst-launch-0.10 -q  videotestsrc ! filesink 2>/dev/null
ERROR: from element /GstPipeline:pipeline0/GstFileSink:filesink0: No file name
specified for writing.
Additional debug info:
gstfilesink.c(424): gst_file_sink_open_file ():
/GstPipeline:pipeline0/GstFileSink:filesink0

$ gst-launch-0.10 -q  videotestsrc ! filesink >/dev/null
ERROR: Pipeline doesn't want to pause.

# one ERROR line goes to stdout, the other goes to stderr

# this is what i would want:
#  * --quiet takes away ALL progress/debug messages and only shows error
#      messages
#  * all error messages goes to stderr
