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.

8a044de701 basevideoenc: do not try to calculate latency from an unknown framerate 
It'll divide by zero, and latency is unknown for an unknown framerate.

Fixes an assert in the schroenc test.

d576e23aa4 basevideoencoder: Proxy the width/height/framerate/PAR constraints of downstream caps to upstream 
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.

Code based on Mark Nauwelaerts audio encoder base class.

9238647314 photography: add missing FLICKER_REDUCTION capability 
GstPhotography API contains functions to get/set flicker reduction
mode, but GstPhotoCaps enumeration doesn't have item for it, so elements
are not able to report whether they support this feature or not.
Also add useful GST_PHOTOGRAPHY_CAPS_ALL for easily selecting all
capabilities at once.

    basecamerasrc: More cleanup

get_allowed_input_caps is not called anywhere.
