This is a fix for a regression of previous commit, which updates the filters
only when the property is set, because it is also required to update the
filter when the color balance interface change its values.
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed
In addition, updating filter is performed during reconfiguration, if needed.

This patch is a fix for my bad review of commit 6d73ca8d. The element should

only should happen when there a VA display. If there's none, the element
should use the caps template.

gst_video_info_set_format() and gst_video_info_from_caps() call, internally,
gst_video_info_init(), hence it is not required to call it before them. This
patch removes these spurious calls.
Instead of the allowed_srcpad_caps variable, this patch uses the othercaps
from fixate_caps() vmethod to find the preferred caps feature and color
format.
https://bugzilla.gnome.org/show_bug.cgi?id=758548
When running transform_caps() vmethod, returning the srcpad caps, the caps are
early restricted to the element properties set: width, height, format and
force keep aspect.
A new file was added gstvaapipostprocutil.{c,h} where the utilities functions
are stored.
https://bugzilla.gnome.org/show_bug.cgi?id=758548
In bug 757598 was added the set_context() vmethod chain up in
GstVaapiPluginBase. But it is buggy, since the parent_class address is
assigned to the last element which called gst_vaapi_plugin_base_class_init().
No error has shown up since none of the element's base classes redefined
set_context() vmethod from GstElement, so always the correct function was
called. Still this code is wrong and this patch make it right.
Since set_context() is the same code, a macro is used to implement that code
in all the gst-vaapi elements.

Since commit 859a2b2, in vaapidecode, allocation query can be different from
the negotiated caps.
When connecting the vaapidecoder to the vaapipostprocessor, the last one will
resize the frame to the negotiated, if and only if, some other parameter is
activated to avoid the passthrough. If it is not, the surface won't be mapped
into a image. If not, the image won't be resized and the output buffer would be
mapped.
This patch will break the passthrough if the allocation query is different
from the negotiation caps, forcing the resizing.
https://bugzilla.gnome.org/show_bug.cgi?id=765095
Instead of using the srcpad template caps for filtering the peer caps, the
function gst_vaapi_find_preferred_caps_feature(), now receives a new parameter
for the element's allowed caps.
With this modification, the vaapipostproc element simplifies a bit its code.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
The native format parameter in gst_vaapi_find_preferred_caps_feature() can be
saved if the out format is used for both: in and out. Thus the code is more
readable.

When resolving bug 753914, a custom allocation query was added, overlapping

The plugins should not expose the feature meta:GstVideoGLTextureUploadMeta in

-- Maintaing decoded surface resoluton and actual display resoultion separately
-- Before pushing every frames downstream, check for the requirement of pool negoation and
output_state negotiation: This is needed to avoid multiple issuses with cropping,
multi-resoluton video handling, more complex multi resolution decode scenarios for vp9decode,
possible wrong behaviour from upstream element to report uncropped values etc. Due to these reasons,
We can't just reliably use the resolution change notification from libgstvaapi for pool renegotiation too.
This is slight overhead, but safe enough. Optimization could be possible though.

In order to reduce the noise, the query type log was downgrade from INFO to
DEBUG, and the shared display address log message is assigned to the object.
The problem with this is that creating the filter causes the display to
be selected, and the caps query happens while linking the element. So,
if the downstream or upstream element is using a specific display
object, it won't be propagated correctly to the postproc as it already
has a display at this point.

Some frameworks (EFL) expect BGRA textures for storage. However,
adding support for that broadly into GStreamer framework implies
two kinds of hacks: (i) libgstgl helpers currently do not support
BGRA textures correctly, (ii) we need to better parse downstream
suggested caps and intersect them with what the VA plugin elements
can offer to them for GL texturing.
Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.
This is an API/ABI change, and SONAME version needs to be bumped.
Otherwise restarting may fail because the state of vaapipluginbase and
vaapipostproc don't match. e.g. gst_vaapipostproc_set_caps() will skip
initailization and not call gst_vaapi_plugin_base_set_caps()
If the best downstream capsfeature turns out to be GLMemory, then make
sure to propagate RGBA video format in caps to that element. This fixes
the following pipeline: ... ! vaapipostproc ! glimagesink.
When an explicit output video format is selected, from an src pad
capsfilter, make sure that the downstream element actually supports
that format. In particular, fix crash with the following pipelines:
... ! vaapipostproc ! video/x-raw,format=XXX ! xvimagesink ; where
XXX is a format not supported by xvimagesink.
While doing so, also reduce the set of src pad filter caps to the
actual set of allowed src pad caps.
In the current implementation, gst_video_info_set_format() would reset
the whole GstVideoInfo structure first, prior to setting video format
and size. So, coleteral information like framerate or pixel-aspect-
ratio are lost.
Provide and use a unique gst_video_info_change_format() for overcome
this issue, i.e. only have it change the format and video size, and
copy over the rest of the fields.

This is a workaround until auto-plugging is fixed when
format=ENCODED + memory:VASurface caps feature are provided.
Use the downstream negotiated video format as the output video format
if the user didn't ask for the colorspace conversion explicitly.
Usecase: This will help to connect elements like videoscale, videorate etc
to vaapipostproc.

If no explicit output surface format is supplied try to keep the one
supplied through the sink pad caps. This avoids a useless copy, even
if things are kept in GPU memory.
This is a performance regression from git commit dfa70b9.
If only advanced deinterlacing is requested, i.e. deinterlacing is
the only active algorithm to apply with source and output surface
formats being the same, then make sure to enable VPP processing.
Otherwise, allow fallback to bob-deinterlacing with simple rendering
flags alteration.
Default to I420 format for output surfaces so that to match the usual
GStreamer pipelines. Though, internally, we could still opt for NV12
surface formats, i.e. default format=ENCODED is a hint for that, thus
delegating the decision to the VA driver.
Use the new gst_caps_has_vaapi_surface() helper function to detect
whether the sink pad caps contain native VA surfaces, or not, i.e.
no raw video caps.
Also rename is_raw_yuv to get_va_surfaces to make the variable more
explicit as we just want a way to differentiate raw video caps from
VA surfaces actually.
The "discontinuity" tracking code, whereby lost frames are tentatively
detected, is inoperant if the sink pad buffer timestamps are not right
to begin with.
This is a temporary workaround until the following bug is fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=734386
In order to make the discontinuity detection code useful, we need to
detect the lost frames in the history as early as the previous frame.
This is because some VA implementations only support one reference
frame for advanced deinterlacing.
In practice, turn the condition for detecting new frame that is beyond
the previous frame from field_duration*2 to field_duration*3, i.e.
nothing received for the past frame and a half because of possible
rounding errors when calculating the field-duration either in this
element (vaapipostproc), or from the upstream element (parser element).
This is a regression introduced with commit faefd62.

Move common VA display creation code to GstVaapiPluginBase, with the

All plug-ins are updated to cope with the new internal APIs.

doesn't fit with the existing decode pipeline that only has 4 extra
scratch surfaces.
Also optimize references tracking to be only enabled when needed, i.e.
when advanced deinterlacing mode is used. This means that we don't
need to track past references for basic bob or weave deinterlacing.
In "mixed" interlaced streams, the buffer contains additional flags that
specify whether the frame contained herein is interlaced or not. This means
that we can alternatively get progressive or interlaced frames. Make sure
to disable deinterlacing at the VPP level when the source buffer is no longer
interlaced.
Fix memory leaks with advanced deinterlacing, i.e. when we keep track
of past buffers. Completely reset the deinterlace state, thus destroying
any buffer currently held, on _start(), _stop() and _destroy().
Port vaapipostproc element to GStreamer 1.2. Support is quite minimal
right now so that to cope with auto-plugging issues/regressions. e.g.
this happens when the correct set of expected caps are being exposed.
