b11342d325 camerabin2: Reset all elements on video recording branch before capture
We need to reset the elements from the video recording branch, including
the queue and capsfilter in order to clear the eos state and activate
the pads.

This makes it possible to record multiple videos with camerabin2 in a
sequence, otherwise the source would get a unexpected return and
push EOS, stopping the whole pipeline.

122a7bd556 camerabin2: Various fixes
As video recording bin's state is locked, we should always
remember of setting it to NULL when camerabin2 goes to NULL

Be more careful when using elements that might not
have been created yet

And do not set location property recursively on videorecordingbin

ba878c95b2 camerabin2: adds location property
Adds a location property to enable applications to select
the captured files names. Locations are handled just like
multifilesink ones

Also disables -Wformat-nonliteral to allow to use non-literals
on g_strdup_printf on camerabin and generate a sequence of
locations for captures.

cb915196e2 camerabin2: Handle vidbin state change individually
Keep vidbin state locked to avoid it going to playing without
being used and leaving an empty file created.

Check the docs on the code for details on the handling.

the --enable-experimental flag is on.

Also add a note to the docs.

5be441adff v4l2camerasrc: Add ready-for-capture property
Adds property that informs if v4l2camerasrc is available
for starting a new capture.

It is useful for applications to know (via deep-notify) when the
property changes and a new capture is possible. Note, however, that
starting a new capture from the notify callback will cause a deadlock.

bd89d22da9 camerabin2: Update v4l2camerasrc to use start/stop signals
Removes the old logic for v4l2camerasrc that used the mode
property switching to start/stop captures to make it identical
to camerabin2 behavior and to allow the future addition of
pausing a video recording.

This also removes the MODE_PREVIEW as it became useless.

91b7f2d99e v4l2camerasrc: Implement video capture
Implements video capture on v4l2camerasrc by using the mode property,
when mode is set to video, the pad probe pushes a new segment
and starts pushing buffers on the pad, when it the property is
sent back to preview, the pad probe pushes an EOS and stops
pushing buffers.

This is controlled by a Recording State variable, that is protected
by the GST_OBJECT_LOCK. I don't think locking for every buffer is
nice, so we could find an alternative lockless way here.

6c7d7946f5 camerabin2: Keep mode definition at -enum file
Use 'mode' enum definition from gstcamerabin-enum file to avoid
conflicts between v4l2camerasrc and gstcamerabin2 modes.

For now there is a MODE_PREVIEW there that is only used on the
camerasrc, not sure if we are keeping it at the future, but for
now this works.
