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.

18602e6e4e wrappercamerabinsrc: Avoid clearing recording caps
When recording 2 videos in sequence with the same video-capture-caps,
the second video would get a not-negotiated error because the
src caps were being cleared without any intention of
renegotiating it back to the requested capture caps.

This patch avoids this caps reset procedure unless a new
caps was set.

b56d9d3ba0 wrappercamerabinsrc: Check for downstream caps on first captures
Use video_renegotiate and image_renegotiate booleans to make
the videosrc negotiate the capture caps on the first capture because
the caps might be set before wrappercamerabinsrc goes into PLAYING
and pads drop the internal renegotiate event.

This is required as the output-selector is using the 'none' negotiation
mode.

4da517ae87 wrappercamerabinsrc: Avoid fixating capture caps
When setting the internal capsfilter caps for capture we should put
the full caps instead of trying to fixate it ourselves. This way we let
the elements (and mostly the source) select the best format instead
of defaulting to what the pad fixation function picks.

48b05a3002 wrappercamerabinsrc: Fix preview messages
Image previews where being posted in sync with the buffers
timestamps, this makes no sense as previews should be posted ASAP.

Also adds some debugging messages.

1a62d9374b wrappercamerabinsrc: Handle src state change to avoid losing timestamps
Camerabin2 uses state changes to force the source to renegotiate its
caps to the capture formats. The state changes makes the source lose
its clock and base_time, causing it to stop timestamping the buffers.

We still need a proper way to make sources renegotiate its caps, so this
patch is a hack to make the source continue timestamping buffers even
after changing state. The patch works by getting the clock and base
time before doing the state change to NULL and setting them back
after putting it to PLAYING again. It also cares to drop the first
new segment after this state change.

9863feb328 camerabin2: Implement previewing
Implement previewing functionality using 2 properties. A boolean
(post-previews) that indicates if previews should be posted, and a
GstCaps (preview-caps) to provide the desired preview caps.

wrappercamerabinsrc implements previewing by supplying the captured
image to a pipeline to adapt it to the required caps before posting.

1c761196f7 wrappercamerabinsrc: Refactor internal pipeline
Instead of linking 3 src pads from tee to the ghostpads, use 2
srcpads and add an output-selector to completely split caps
negotiation of video/image modes. I don't think there is an
use case that would require image and video pads to be used
at the same time.
