43ec4f46b8 basecamerasrc: Fail state change if preview pipeline fails creation
If the preview pipeline fails creation, for any reason, we should
fail basecamerasrc state change.

Also adds a missing g_return_if_fail check to preview pipeline
functions

12f77b27e2 camerabin2: preview: No need for appsink to store the last buffer
There is no need for preview's appsink to keep a reference to the last buffer,
so disable the property to make it unref the buffers sooner.

d41af4e2f8 camerabin2: preview: Remove one of the two colorspace converters
The preview pipeline doesn't need 2 colorspace converters, remove
one to speed up caps negotiation and reduce the delay on getting
the first preview buffer out of the preview pipeline.

It shouldn't cause problems as videoscale and ffmpegcolorspace seems
to handle the same caps, so no conversion should be needed for
videoscale. Additionally, camerabin1 has been working with a similar
pipeline with a single ffmpegcolorspace and no bugs have been open about it
so far.

e17d99c4c4 basecamerabinsrc: Optimize preview pipeline startup
Use gst_element_link_pads_full to optimize preview pipeline startup,
leading to a faster camerabin2 startup as well.

058a3d9d4c basecamerasrc: remove unused get_allowed_input_caps
The use of this method was removed in:
    commit 539f10f4d9
    basecamerasrc: More cleanup

The code from wrappercamerabinsrc is from v4l2camerasrc but is unused:
get_allowed_input_caps is not called anywhere.

c86d662b23 basecamerabinsrc: Handle errors from preview pipeline
Implements a message handling function to preview pipeline bus.
If GST_MESSAGE_ERROR is seen, considers preview pipeline unable
to do its job and posts an error message to application.

Sets pipeline element to NULL so that subsequent calls to post_preview
and set_caps functions just returns without pushing anything to the
disposed preview pipeline. Leaves further actions to the application.

802028081c basecamerabinsrc: Protection for previewpipeline when setting new preview caps
Implements a state indicating flag to preview pipeline,
so that new caps are not set if the pipeline is processing a
preview. The caps are set as pending and applied when the
next preview post is called.

In this case a wait was implemented in the post_preview function,
so that new preview image buffer will wait until the other previews
have been posted to the application and the new caps can be used
safely.

17fd7ebcb4 android: make it ready for androgenizer
Remove the android/ top dir
Fixe the Makefile.am to be androgenized

To build gstreamer for android we are now using androgenizer which generates the needed Android.mk files.
Androgenizer can be found here: http://git.collabora.co.uk/?p=user/derek/androgenizer.git

6a686316d5 basecamerasrc: camerabin2: wrappercamerabinsrc: Add read-only max-zoom prop
This is not implemented in any of our real sources to which wrappercamerabinsrc
might connect but this is optional and can be implemented at any time. A
limit on the software zoom level using video{crop,scale} would be arbitrary.

aa7b962891 camerabin2: Improve idle property usage
Use resource warning messages to notify camerabin2 that a capture
as aborted or couldn't be started, making it decrement the
processing counter and making the idle property more reliable.

2da37d966d basecamerabinsrc: Check if set preview caps are the same
Checks if the new received preview-caps are equal to what is
already in use, skips the preview-caps setting logic in case
new caps are same as current ones.

76b3ff361f basecamerasrc: add virtual function to notify subclass of changing preview caps
Adds a virtual function to basecamerasrc in case subclasses want to be
notified of changing preview caps. This is useful if the subclass wants
to post the preview itself or if it wants to provide a preview buffer
as close to as possible to the user's requested resolution to the
preview generation pipeline.

ea959add31 basecamerasrc: Add some more logging
Adds some more logging and always assume capture has started before
start_capture is called. This helps on image captures that might
call finish_capture directly from start_capture or before start_capture
finishes.
