7c1da700c4 video: Add multiview/stereo support 
Add flags and enums to support multiview signalling in
GstVideoInfo and GstVideoFrame, and the caps serialisation and
deserialisation.

videoencoder: Copy multiview settings from reference input state

Add gst_video_multiview_* support API and GstVideoMultiviewMeta meta

992101f82a videoencoder: Keep sticky events around when doing a soft reset 
The current code will first discard all frames, and then tries to copy
all sticky events from the (now discarded) frames. Let's change the order.

aa645b11f1 video{enc,dec}oder: Don't reset latency all the time and handle max=GST_CLOCK_TIME_NONE correctly 
max=NONE means that *this* element has no maximum latency. If upstream had a
maximum latency we must not override it with NONE.

87d6c265a8 video{en,de}coder: Call reset() before the start() vfunc 
This makes sure that the element is in the same state before start() is called
the very first time and every future call after the element was used already.

Also it ensure that we always have a clean state before start(), cleaned the
same way in every case.

098b42f36b video{en,de}coder: Reset the codec after calling the stop() vfunc 
The stop() vfunc might mess with some of our fields we have just
reset, which could cause memory leaks or invalid state taken over
to later.

Also the stop() vfunc, or anything called until it from another thread,
might want to be able to use the fields that were just resetted and
become confused because of that.

In the decoder we already had a workaround for things like this happening,
this workaround is not needed anymore.

f24075887f videodecoder: implement caps query

7b428a8bcb videoencoder: Stop storing if we received EOS 
This was never reset when going from PAUSED->READY and resulted
in encoders being not reusable after EOS. They just rejected any
buffer because they received EOS in their previous life.

The flag wasn't used anywhere except for rejecting buffers after
EOS, and this is now handled by GstPad directly.

79ef75888c videodec/enc: clear reconfigure flag if negotiate succeeds 
So that it avoids to send an allocation query twice.
One from an early call to gst_video_encoder_negotiate from a
subclass, then one from gst_video_encoder_allocate_output_frame.
Which means that previously gst_video_encoder_negotiate was not
clearing the GST_PAD_FLAG_NEED_RECONFIGURE even on success.
