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=753854

--performance-measure Collect timing information about the
|
|
captures and provides performance statistics at the end
|
|
--performance-targets A list of doubles that are the performance target
|
|
times for each of the measured timestamps. The order is
|
|
startup time, change mode time, shot to save, shot to snapshot,
|
|
shot to shot, preview to precapture, shot to buffer.
|
|
e.g. 3.5,1.0,5.0,2.5,5.0,1.5,1.0
|
|
* Startup time -> time it takes for camerabin to reach playing
|
|
* Change mode time -> time it takes for camerabin to change to the selected
|
|
mode in playing
|
|
* Shot to save -> time it takes from start-capture to having the image saved
|
|
to disk
|
|
* Shot to snapshot -> time it takes from start-capture to getting a snapshot
|
|
* Shot to shot -> time from one start-capture to the next one
|
|
* Preview to precapture -> time it takes from getting the snapshot to the
|
|
next buffer that reaches the viewfinder
|
|
* Shot to buffer -> time it takes from start-capture to the moment a buffer
|
|
is pushed out of the camera source
