           Summary: [GTK] Add support for graphviz debug output for the
                    gstreamer video pipeline
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Enhancement
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.xavier at undefinedltd.co.uk


GStreamer has a useful debugging feature where it can output a given pipeline to a Graphviz dot file. Having this feature enabled in WebKit would be helpful for debugging development/end user problems with the video pipeline.

Some more information on this feature (along with an example) can be found in the GStreamer SDK documentation http://docs.gstreamer.com/display/GstSDK/Basic+tutorial+11%3A+Debugging+tools

The following patch will output a dot file for errors and state changes in the video pipeline when the environment variable GST_DEBUG_DUMP_DOT_DIR is set. This is similar to how gst-launch implements the same functionality.
