Hi,


-- steps to reproduce:

set GST_DEBUG_DUMP_DOT_DIR=.
set GST_DEBUG=2
gst-launch-0.10 fakesrc num_buffers=10 ! fakesink

-- result:

gst\gstdebugutils.c:571:_gst_debug_bin_to_dot_file:←[00m Failed to open file 'c:\0:00:00.170245000-gst-launch.NULL_READY.dot' for writing: Invalid argument

-- infos:

it fails on:  fopen (full_file_name, "wb")

On windows, a file name cannot contains any of the following charaters:
\ / : * ? " < > |
And in the timestamp there is: ':'

g_strdup_printf ("%" GST_TIME_FORMAT "-%s", GST_TIME_ARGS (elapsed),
      file_name);

and #define GST_TIME_FORMAT "u:%02u:%02u.%09u"

-- other:

I can make a patch that just replace the 2 characters ':' by a '_' but I would like to know what do you think about it first.
