14acb6fb37 gst: remove unnecessary GLIB_DISABLE_DEPRECATION_WARNINGS
There are unnecessary definitions for disabling deprecation warnings.
Since GLIB_DISABLE_DEPRECATION_WARNINGS is not needed anymore in these files,
removing the same.

5d1fedd18e wrappercamerabinsrc: Unref elements after usage
gst_bin_get_by_name() and gst_bin_get_by_interface() both return
references to elements that need to be unreferenced after usage.

a70764df5a wrappercamerabinsrc: do not give references to probes
They are kept until the probes are removed but they will never be
removed as the refcount of the element won't get to 0 because the
probes own references (cyclic refs). As the probes should only be
running as long as the element is running there is no need to
secure a ref for them.

Removes 3 leaked refs of wrappercamerabinsrc

362951b9ec wrappercamerabinsrc: Fix caps filter caps proxying
The notify signal is triggered when caps is changed. But instead of
proxying the fixed caps, we query for the caps. Hence, when we go to
READY state, we endup setting template caps on the proxied caps
filter instead of NULL, which leads to negoitation failure. Correctly
proxy NULL caps if this is the new caps. Fixes not negotiated error
when running in cheese. Also fix a leak of caps string in one of the
trace.

cfda1aafa3 wrappercamerabinsrc: stop source to do internal reconfiguration safely
In order to be able to change the caps on multiple capsfilters the
source element needs to be stopped, otherwise it will get a few
reconfigure events and might try to renegotiate while the bin
is still transitioning its caps, leading to a not-negotiated failure
and the image capture won't happen because the source will be
unusable.

The solution is to keep the source in paused while the caps are being
changed in the bin, and then bring the element back to playing once
it is done. Unfortunately this increases the image capture latency,
but it should always work.

A possible improvement to reduce the latency is to add another signal
to be called before 'start-capture': 'prepare-capture'. At this step
the camera source should set all caps it needs and get the source
ready for doing the capture as soon as 'start-capture' is called.
This can be done on a future commit

28e64d1031 wrappercamerabinsrc: Add video-source-filter during construction
By adding the video-source-filter during construction time, rather then
patching it in later (*), we can greatly reduce the amount of caps involved
in negotation, speeding up pipeline creation.

I wrote this while working on speeding up the startup of cheese. My cheese
has been modified to add a capsfilter, filtering for only the configured
resolution, with that cheese patch + this patch, the pipeline creation time
goes from aprox 1.1 seconds to aprox 350ms. This is with a Logitech 9000
pro camera, which supports lots of different resolutions at many different
framerates per resolution, causing a caps "explosion" if not filtered.

*) Note the code for this is left in, as it is still necessary if the
video-source-filter is changed between a stop + re-start.

8dc7fae455 wrappercamerabinsrc: Don't unset the video-source property on pipeline start
check_and_replace_src() was setting self->app_vid_src to NULL, which
means that an app setting the video-source property, and then starting,
stopping and re-starting the pipeline (ie to make changes to the
video-source-filter property) would after the restart no longer have
a video-source.

This patch fixes this by making gst_camerabin_setup_default_element return a
ref to the passed in user_element, rather then returning the user_element as
is, so that that ref can be passed on to the bin, and the app_vid_src ref
stays valid.
