The encoder is a true gstobject now and all the properties are using
gobject's properties mechanism. Add help functions to handle the properties
between encode and encoder class.
The basic idea is mapping the same property between encoder and encode. All
the encoder's properties will have the same name, the same type in encode.
The set/get property function just forward the property setting/getting to
the encoder using the same property name and value. Because the encoder is
created on needed, we need to cache the property setting in encode.
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.
Install properties for h264 encoder fei class. Also set the new get/set
property functions for gobject class. Still use the old properties
way now and this new feature will be enabled later.

Replace all gstvaapiobject in vaapi encoders with standard gstobject.
Let the gstobject common logic to handle all the init and finalize
works. But the property install/set/get still use the old way, need
to be improved later.
While ensuring the allowed sink pad caps, the filter attributes set
the frame size restriction, but it is not ensured, at that moment,
that the filter is already instantiaded.
In order to silence the glib logs, this patch add only calls
gst_vaapi_filter_append_caps() if the filter is instantiated.
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.
It is requiered to know if postproc is capable to change the video
direction before fixating the source caps.
In order to do it, it'ss required to know if there's a functional VPP,
but that's checked at create() vmethod, which occurs after caps
fixating.
This patch checks for a functional VPP at fixate caps and, if so,
checks for the enabled filtes and later do the caps fixations.
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.
