------- Comment #15 from Stefan Kost (gstreamer, gtkdoc dev)  2007-10-18 13:37 UTC -------
Right now one uses macros like:

GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS(GST_BIN(pipeline),GST_DEBUG_GRAPH_SHOW_ALL,"/tmp/gst-launch.%"
GST_TIME_FORMAT ".dot");

in the code and an environment variable like GST_DEBUG_DUMP_DOT_FILES=1 at
runtime to activate it. What about making the macros simpler:

GST_DEBUG_BIN_TO_DOT_FILE(GST_BIN(pipeline),GST_DEBUG_GRAPH_SHOW_ALL);

and passing the base-filename via environment var:

GST_DEBUG_DUMP_DOT_FILES="/tmp/gst-launch."

If the envvar is empty - no dumps will be made. If the envvar contains
something it will create names by appending the timestamp + ".dot".


One thing I wold like to have (but I am too lazy to write) is a UI app. I get
stwo arguments: a gstremaer log-file and the same basename as above.
The ui shows the picture in the upper half and the log in the lower half.
When clicking a log-line it would load the picture with the closest (?)
timestamp in the name.
The tool could also run dot to make the pictures for the dot files initialy.
Any volunters?
