Víctor Manuel Jáquez Leal 4be3413fec vapostproc: Process HDR caps
This patch adds a new parameter: hdr-tone-mapping (same as
vaapipostproc), if the HDR capabilites are availabe in driver, and
it's disabled by default.

If hdr-tone-mapping is enabled then HDR fields in sink caps are
processed in frames from HDR to SDR, removing those hdr fields in
source pad caps too.

hdr-tone-mapping is not enabled if a color conversion is also
requested, since it fails to process in the iHD driver, so far.

Víctor Manuel Jáquez Leal 5e4c152de4 va: Remove libgudev crumbs in library.
In commit e699aaeb we moved linking of libgudev to the plugin rather
the library, because it's only used in the plugin. But the dependency
check is still done in library.

This patch removes the dependency check in library, and updates the
dependency check in plugin.

Seungha Yang 6434d69f8c codecs: Stop claiming constness for refcounted object
It's almost pointless and makes little sense as subclass might
want to modify refcount of the object or so. And all subclasses
are already casting them to non-const version as well.
In a general sense, we need to avoid passing refcounted object
with const qualifier.

Víctor Manuel Jáquez Leal d86288904f vapostproc: Make cb max values symmetrical to their min values.
Intel drivers expose some colorbalance's maximum values much more
bigger than their minimum values, given their middle values (default
value). This means, in practice, that the real middle point between
the maximum and minimum values implies a major change in the color
balance, which is not expected by the GStreamer color balance logic.

This patch makes the given maximum value symmetrical to the minimum
value, given the middle one (default value).

Víctor Manuel Jáquez Leal c7e52e869d va: filter & postproc: Match color with caps features.
When fixating color, there might be "other caps" with color spaces not
supported by the caps features exposed in the vapostproc's source pad
caps template (perhaps it's a bug somewhere else in GStreamer).

This solution checks if the proposed format exists in the filter
within the caps feature associated with the proposed format.

The check is done with the new filter's function
gst_va_filter_has_video_format().

The current code does not set the copied memory correctly when it is popped
from the surface cache pool.
1. We forget to ref the allocator, which causes the allocator to be freed
   unexpected, and we get a crash later because of the memory violation.
2. We forget to add ref_mems_count, which causes the surface leak because
   the surface can not be pushed back to the cache pool again.

Víctor Manuel Jáquez Leal 4a4823b972 va: Delay decoders downstream negotiation.
Delay decoders downstream negotiation just before an output frame
needs to be allocated.

This is required, are least for H.264 and H.265 decoders, since
codec_data might trigger a new sequence before finishing upstream
negotiation, and sink pad caps need to set before setting source pad
caps, particularly to forward HDR fields. The other decoders are
changed too in order to keep the same structure among them.

Using GstBaseDec hack to access the parent_object of each element in
the element itself is a bit fragile. It would be better to keep its
own parent object as the usual global variable. It would make it
resistant to code changes.

The GstBaseDec macro to access the parent object now it's internal to

Víctor Manuel Jáquez Leal cf3d271cde vapostproc: Color fixation will choose othercaps' structure.
gst_va_fixate_format() will iterate all othercaps' structures to find
the one with less information lost at color conversion. If a structure
with same color format is found, the iteration stops. It's like a
smart truncation. Then, this function also will choose the caps
feature.

Later this structure is used fixate its size and no further truncation
is needed.

Don't intersect at fixate, since it kills possible resizing.

Mengkejiergeli Ba 164244a2eb va: allocator: Fix possible memory leaks
At gst_va_dmabuf_allocator_setup_buffer_full, static code analysis tool
does not know number of objects in descriptor is always larger than 0 if
export_surface_to_dmabuf succeeds. Thus, the tool will assume buf is
allocated with mem but not released when desc.num_objects equals to 0
and raise a mem leak issue.

For gst_va_dambuf_memories_setup, we should also inform the tool that
n_planes will be larger than 0 by checking the value at very beginning.
Then, the defect similar to above will not be raised during static analysis.

So, instead of two nested loops, now the function is a single loop,
traversing @caps to find if each structure already contains the requested
@features_name.

It's important to add missing caps features with @caps, in order to
not lost information.

Víctor Manuel Jáquez Leal e699aaeb16 va: meson: Move back libgudev dependency to plugin.
When move the libgstva, libgudev dependency was moved as part of the
library, though it's not use by the library but the plugin. This patch
moves back libgudev dependency to the plugin.

Also HAVE_LIBDRM is move to the library which is the one who use it.

Víctor Manuel Jáquez Leal 5e08ede8f6 va: meson: Update and enhance meson syntax usage.
This patch contains two updates:

1. Instead of checking for dependency already checked just to verify a
   version, we use the dependency version API.
2. Update the deprecated function get_pkgconfig_variable.
