dfdc6255f8 camerabin2: Fix tag handling for videos
In video mode the tags should be pushed after sending the start capture
to the source, this allows the video recording elements to be reset
and leave the flushing state they were at after a previous capture.

This fixes the problem where tags only work for the first video capture

d2e1f1bdc6 camerabin2: Only mark video capture as finished after EOS
Instead of probing the videosink sinkpad for passing EOS, better
to wait for EOS from the bus.

This makes sure the filesink has already processed it and is
ready to close the file. This is used to notify applications
that camerabin2 is idle and can be shut down.

6a686316d5 basecamerasrc: camerabin2: wrappercamerabinsrc: Add read-only max-zoom prop
This is not implemented in any of our real sources to which wrappercamerabinsrc

limit on the software zoom level using video{crop,scale} would be arbitrary.

6913db30f8 camerabin2: No need to force audiosrc to null on stop_capture
Setting the audio source to null isn't needed and it could
make the EOS that is still flowing be dropped if autoaudiosrc

from the real source.

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.

3d1a7b0021 camerabin2: Force EOS on audio src
We can't rely on audio sources pushing EOS when going PAUSED->READY
because this is a basesrc bahavior and when used inside autoaudiosrc
the ghostpad goes flushing before the real source pushes the EOS,
so it is dropped.

fc9c9b0f24 camerabin2: Handle audio elements states
Audio elements are put into bin only when needed, so we need

b56d9d3ba0 wrappercamerabinsrc: Check for downstream caps on first captures
Use video_renegotiate and image_renegotiate booleans to make

4da517ae87 wrappercamerabinsrc: Avoid fixating capture caps

of defaulting to what the pad fixation function picks.

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.

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

Adds a location property to enable applications to select

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.

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.

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.
