Sure, for me the most interesting ones are --gst-debug-level=4 (which
helps me to know which elements are being used in our pipelines) and
often I do --gst-plugin-path=/usr/lib64/gstreamer-1.0 to load plugins
from my system instead of JHBuild environment.

Both of them are available using environment variables but command line
support is easier to set (even more in windows)

All options in --help-gst are:
 --gst-version                    Print the GStreamer version
 --gst-fatal-warnings             Make all warnings fatal
 --gst-debug-help                 Print available debug categories and exit
 --gst-debug-level=LEVEL          Default debug level from 1 (only error) to 9 (anything) or 0 for no output
 --gst-debug=LIST                 Comma-separated list of category_name:level pairs to set specific levels for the individual categories. Example: GST_AUTOPLUG:5,GST_ELEMENT_*:3
 --gst-debug-no-color             Disable colored debugging output
 --gst-debug-color-mode           Changes coloring mode of the debug log. Possible modes: off, on, disable, auto, unix
 --gst-debug-disable              Disable debugging
 --gst-plugin-spew                Enable verbose plugin loading diagnostics
 --gst-plugin-path=PATHS          Colon-separated paths containing plugins
 --gst-plugin-load=PLUGINS        Comma-separated list of plugins to preload in addition to the list stored in environment variable GST_PLUGIN_PATH
 --gst-disable-segtrap            Disable trapping of segmentation faults during plugin loading
 --gst-disable-registry-update    Disable updating the registry
 --gst-disable-registry-fork      Disable spawning a helper process while scanning the registry

Cheers,
