When g_option_context_parse fails, context and error variables are not getting free'd which results in memory leaks. Free'ing the same. And replacing g_error_free with g_clear_error, which checks if the error being passed is not NULL and sets the variable to NULL on free'ing. https://bugzilla.gnome.org/show_bug.cgi?id=753851

/* Create a PTP client clock and print times and statistics.
|
|
*
|
|
* When running this from a GStreamer build tree, you will have to set
|
|
* GST_PTP_HELPER to libs/gst/helpers/.libs/gst-ptp-helper and also
|
|
* make sure that it has the right permissions (setuid root or appropriate
|
|
* capabilities
|
|
*
|
|
* You can test this with any PTP compatible clock, e.g. ptpd from here: http://ptpd.sourceforge.net/
|
|
*
|
|
* For testing the accuracy, you can use the PTP reflector available from
|
|
* http://code.centricular.com/ptp-clock-reflector/ or here
