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.
GstVaapiMiniObject and GstVaapiObject are deprecated.
This is the first step to remove them by porting GstVaapiCodedBuffer

The GstVaapiMiniObject is obsolete and we need to replace it.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.

`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.

`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.

If the FEI mode is not handled the created resources should be

The system resource will not be reclaimed and reused, reducing the

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.
Found by static analysis. encoder->mb_width * encoder->mb_height
is evaluated using 32-bit arithmetic before widen. Thus, cast
at least one of these to guint64 to avoid overflow.
The YUV formats have no ambiguity for drivers, so we can add them all.
Some old driver(i965) does not implement full get/put image functions
but can use derive image funtions for the YUV format. It does not
report that kind of formats correctly in image query, but will derive
that YUV format image from surface. The dynamic mapping of YUV format
will block that manner.
Adding more YUV format mapping has no side effect. So considering the
legacy driver conformance, we add all YUV formats mapping statically
and dynamic mapping RBG formats

Multiple different scenarios could break the display thread creation and
end up blocking waiting for thread o be created. Fix them all by
correctly waiting for a new boolean to become valid.
Some streams have error data introducing unknown NAL type. There are
also kinds of NAL types we do not want to handle. The old manner will
set a decoder error when encounter this, which cause a latent crash bug.
The decoder may successfully decode the picture and insert it into DPB.
But there are error NAL units after the AU which cause the post unit error
and make that frame dropped. The later output of the picture still want
to ref that frame and crash.
No need to set decoder error when can not recognize or handle the NAL
unit, just skip it and continue.
Fix: #191
This patch makes use of GST_PARAM_USER_SHIFT to define the internal
param in encoders to decide which parameters to expose. Thus
gstreamer-vaapi will not interfere with any change in GStreamer in the
future.
Also, the internal symbol was change to
GST_VAAPI_PARAM_ENCODER_EXPOSURE to keep the namespacing.
The command line:
gst-launch-1.0 filesrc location=some_name.mjpeg ! jpegparse !
vaapijpegdec ! videoconvert ! video/x-raw,format=I420 ! vaapisink
will crash on i965 driver because of no pointer check.
We now generate the video format map between GST format and VA format
dynamically based on the image format returned by vaQueryImageFormats.
i965 driver does to report image format of 444P and Y800 forcc, while
the jpeg decoder context VASurfaceAttribPixelFormat use them. We can
not recognize these format and pass a NULL pointer to
gst_vaapi_surface_new_from_formats.
We need to add a pointer check here and let the fallback logic handle
this case correctly.
Other drivers work well.
Improve the mapping between va format and gst format. The new map
will be generated dynamically, based on the query result of image
format in VA driver. Also consider the ambiguity of RGB color
format in LSB mode.
We no longer need this obsolete set_property function now after
switch to standard gobject's property manner.
Also delete the old encoder's property enum in the header file.
G_PARAM_CONSTRUCT make all properties init correctly, we do not
need to init the properties manually.
G_PARAM_FLAG_VAAPI_ENCODER_EXPOSURE is a vaapi encoder specific
flag, means need to expose the property to according encode class.

The context overlay was an optimization to apply a video composition
to all the surfaces bound to a context.
But since commit 18031dc6 this optimization was disabled, so it is
better just get rid of it.
In commit 18031dc6 surface's parent context is not assigned because of
circular references. Since then (2013), there's has no issue with
subpictures attached to a context, the current only users of this API.
This patch cleans up all of related code with the unused surface's
parent context.
This code doesn't define the profile used by the internal encoder, but
it used to "predict" which is going to be used and to get the caps
restrictions.
Before the profile was predicted by checking the donwstream caps, but
sometimes they are not defined, setting an unknown profile. In order
to enhances this situation, the encoder asks to internal encoder if it
has one. If so, it is used.
To ask the internal encoder's profile a new accessor function was
added: gst_vaapi_encoder_get_profile()
The return value of vaGetConfigAttributes() of VAConfigAttribRTFormat
is a bitwise flag with *all* the supported chroma types.
Previously it was assumed that the return value was a single value,
thus when returning the GST_VAAPI_CHROMA_TYPE_XXX the code was a
simple case. But it is wrong.
This patch changes the case block with a sequence of ifs testing the
bitwise. For now we assume a "priority" list in the testing sequence.
gst_vaapi_profile_get_name() returns a proper name for
GstCaps. Nonetheless, there are many profiles which don't have a name
representation for that realm.
gst_vaapi_profile_get_va_name() returns the name of the profile
according to its VAProfile name.
This new funtion is used in the encoder error message.
Now that vaapipostproc can possible handle video-direction, it
should also handle the image-orientation event from upstream if
video-direction property is set to auto.
If the video direction is unsupported by the driver, an element
warning is posted in the bus to notify the application.
gst_vaapi_enum_type_get_nick() was added in the library thus it can
be used elsewhere. It retrives the nick from an enum gtype.
This patch locks the display before querying the pipeline caps and
stores the mirror and rotation capabilities, thus they are not queried
every time the video direction is set.
Commit 0afc8131 introduced a regression and only NV12 format were
admitted, failing in any other valid color format.
This patch sets the profile to GST_VAAPI_PROFILE_VP9_0 by default.
When set multiple settings of color balance like hue, saturation,
brightness and contrast for vaapipostproc, they should be set as
parameters of color balance filter, at the same color balance
filter calling.
Otherwise, multiple color balance filter calling will cause
previous setting get reset by the last calling with default value.
Fixes#182.

gst_vaapi_video_pool_reserve_unlocked() hit an undocumented behavoir
because it locks twice the same mutex.
Also, n had different meanings in the current code: as an increase
value and as a new total of allocated surfaces.
This patche removes the undocumented behavoir (usually a deadlock) and
fixes the meaning of n as the new total of allocated surfaces.
