[gst-devel] gst_xml_write_file failing with access violation on Windows XP

[Andreas Schuler]

Thank you very much for your suggestions. The DOT tool is indeed working
great and seems to contain all the data I was looking for.

For anyone else just skimming the documentation, make sure you have the
following environment variable defined:

GST_DEBUG_DUMP_DOT_DIR  (some directory you want GStreamer to write the DOT
files to)

Then generate a PNG file using the following command (which creates a file
called "image.png"):

dot -Tpng -oimage.png  <your file>.dot



Thanks again,

Andreas
