Don't reset the can_dmabuf field. This restores the
close/reset logic that existed prior to commit
ca2942176b in regards to
dmabuf support.
Plugins only call gst_vaapi_plugin_base_set_srcpad_can_dmabuf
once during startup, but may need to reset the other private
fields multiple times during negotiation. Thus, can_dmabuf
should be exempt from the resets.

The old way make the one config for each profile/entrypoint pair,
which is not very convenient for description the relationship
between them. One profile may contain more than one entrypoints
to within it, so a set like data structure should be more suitable.
GstVaapiMiniObject and GstVaapiObject are deprecated.

There are several internal functions with 'create' name, but they
don't create any new structure, but rather it initializes that
structure. Renaming those function to reflect better their purpose.

The GstVaapiMiniObject is obsolete and we need to replace it. This
patch turns GstVaapiContext into a plain C structure with its own
reference counting mechanism.
Also this patch removes unused overlays attributes.

Issue detected by Coverity
`info_to_pack.h264_slice_header` is always allocated by
gst_vaapi_feipak_h264_encode(), thus checking it to free it afterwards
in doesn't make much sense. But it requires to be free on the error
path.
There may be a null pointer dereference, or else the comparison
against null is unnecessary.
In gst_vaapi_encoder_h264_fei_encode: All paths that lead to this null
pointer comparison already dereference the pointer earlier

An unsigned value can never be negative, so this test will always
evaluate the same way.

Issue detected by Coverity
`info_to_pak` variable in gst_vaapi_encoder_h264_fei_encode() is
declared in the stack, but it is free in
gst_vaapi_feienc_h264_encode() as if declared on the heap.
This patch initializes the structure and removes the free.
A non-heap pointer is placed on the free list, likely causing a crash
later.

expression, which can never be heap allocated.

If the FEI mode is not handled the created resources should be
released and return and error code.
The system resource will not be reclaimed and reused, reducing the
future availability of the resource.

The base plugin public API function implementations determine
which pad should be passed to the internal helper functions.
Currently, only the base plugin static sinkpad and static
srcpad are supported/used. However, this change enables future
API functions to be added that can accept a pad (i.e. request pad)
from an element subclass (e.g. a GstVideoAggregator subclass).
Define a struct (GstVaapiPadPrivate) to encapsulate the
pad-specific data (i.e. buffer pool, allocator, info,
caps, etc.).
Add an interface to retrieve the data struct for a given
pad.
Finally, update the base plugin to use the data struct
throughout the implementation.
This will enable us to easily extend the base plugin in the
future to allow for N-to-1 pad subclasses (e.g. overlay/
composite).
We do not need to maintain a standalone list of decoder's output
template for raw formats and that is easy to make mistake(for
example, the AYVU is wrong in that list, should be VUYA).
Just use GST_VAAPI_FORMATS_ALL to replace the raw formats list for
src template.
We need to provide more precise template caps for postproc's src
and sink pads. The GST_VIDEO_FORMATS_ALL make all video formats
available which are really superfluous.
Don't try to decode until the first I-frame is received within the
currently active sequence. i965 H265 decoder don't show any artifact
but it crashes.
Fixes: #98
GST_VAAPI_FORMATS_ALL collects all declared formats in video-format
as a caps template string, and make them available in caps with
memory:VASurface feature.
Fixes: #199
When translating navigation x,y coordinates for
video-direction, it is necessary to subtract 1
when using the video dimensions to compute the
new x,y coordinates. That is, a 100x200 image
should map coordinates in x=[0-99],y=[0-199].
This issue was found with unit tests provided
in !182.
We should halt meson configuration if there is no render API
installed (either DRM, Wayland or X11).
That behavior was already in autotools but missed in meson. This patch
brings it back.
Fixes: #196
The code is essentially the same for getting all op default
values. Thus, use a macro to help minimize code duplication
and [hopefully] encourage using the same mechanism for all
default getters.
Currently the parameter of skin-tone-enhancement filter is forced
to zero. In fact it could be set different value by the user.
So create a new property named as "skin-tone-enhancement-level"
for accepting the used defined parameter value.
At the same time, skin-tone-enhancement is marked as deprecated.
When skin-tone-enhancement-level is set, skin-tone-enhancement
will be ignored.
g_return_val_fail() documentations says:
If expr evaluates to FALSE, the current function should be
considered to have undefined behaviour (a programmer error).
The only correct solution to such an error is to change the
module that is calling the current function, so that it avoids
this incorrect call.
So it was missused in a couple parts of the H264 and H265 internal
decoders. This patch changes that to plain conditionals.
Also, it was included a couple code-style fixes.
The expression "len >= 0" is always true since "len"
is an unsigned type. And it is clear that the writers
intention was not to write "len > 0" since we handle
len == 0 in the ensuing "if (len < 3)" conditional
block.
