ae57a90fe2 camerabin: do not set imagebin sinkpad twice 
If we already have a sinkpad, do not get a new one

16cff06a70 camerabin: add viewfinder-filter property 
Adds a new property called viewfinder-filter to camerabin.
This property is used to add a filter to process the video
flow right before the viewfinder sink.

Also updates test to check property exists.

2c4417dabc camerabin: proxy video source photography interface property notify signals 
If photography interface properties change in video source, notify the
application by emitting notify for respective camerabin properties.

2c05df08b2 camerabin: add api to query supported image capture resolution 
Adds new property 'image-capture-supported-caps' to GstPhotography
to query the supported image capture caps.

d25a9ca8aa camerabin: add video-source-filter property 
Add video-source-filter property that can be used to inject application
specific gstreamer element to camerabin pipeline. The video-source-filter
element will process all frames coming from video source.

One could add image analyzers to collect information about the stream,
or add image enhancers to improve capture quality, for example.

1c74f22264 camerabin: don't try adapting image capture resolution if no source-resize flag 
If source-resize flag is disabled then set resolution to image capture caps
according to capture resolution video source element produces. Otherwise we
write wrong resolution to image metadata.

d7a0f1f997 camerabin: Fix capturing flag handling after image has been captured 
Make sure capturing flag is unset and image-captured message is sent
before sending eos event to image bin and saving the image to a file.

c6f6f1b595 camerabin: fix setting filter-caps property in NULL state 
Split _set_capsfilter_caps() into two parts so that we can call one part
regardless of the element state.

1b10553f90 camerabin: improve image done signal emission 
Use g_idle_add_full() with G_PRIORITY_HIGH to emit image done signal,
g_idle_add() is more likely to starve with higher priority events.

In some error situations the NULL -> READY state change failed
and camerabin elements were not destroyed.

58bf3be730 camerabin: don't use gst_bus_poll() when creating preview image 
Avoid using gst_bus_poll() as the docs recommend. Use
gst_bus_timed_pop_filtered() instead.

be12317653 camerabin: ref element before removing from the bin to resurrect 
This function is not supposed to dispose the element in the case of failure
as the caller is using the elements name in the error message. Also add
some more input parameter checks in the form of g_return_val_if_fail

b890ecd83c camerabin: code cleanups 
Align element initialisation. This should be re-thought, g_object_new zeros things already.
Harmonize the element getters for the src/sinks to return what we actualy use.

52e314ef81 camerabin: set camerabin default sources/sinks like in playbin2. Fixes #574434

0d48f73532 camerabin: handle preview-caps only in image mode and only when they change

eb648817a4 camerabin: fix scene mode setting 
Camerabin caches photography settings, but it didn't take into account
that scene mode setting may change other settings as well. So, config
needs to be read back from device after scene mode is set.

b2fc088c84 camerabin: reset active-pad in output-selector after READY state 
Camerabin sets itself to READY state during resolution change. This
operation makes output-selector to forget its currently active pad,
so it must be set again after state change.

7b62e11412 camerabin: don't reset capsfilters or zoom if error occurs 
If an error occurs, application should set pipeline to NULL, and updating
zoom can actually block message handling if video device driver has failed
and video src element supports zooming using photography interface and S_CROP.

2bb31a8d4a camerabin: reset filename after capture to avoid racy when capturing again 
If we don't reset the filename we cannot check if we still expect the filename
for a subsequent capture pass. The imagebin would good to paused and we set the
filename in that state. This trigers an error-message and would capture to the
old filename.

Stefan Kost
80408b1de2 camerabin: set imagebin to PAUSED on capture and delayed filename setting

3cfe16cc63 photography: declare interface as unstable API by means of a warning 
Application developers won't know right away which module an interface comes from,
