The VP9 spec defines the MAX_TILE_WIDTH_B64(64), which is the maximum
width of a tile in units of superblocks. So the max width of one tile
should not be larger than 64x64=4096. When the width exceeds 4k, we
need to split it into multiple tiles in columns. The current vp9 encoder
does not handle this correctly.
The command such as:
gst-launch-1.0 videotestsrc ! video/x-raw,width=7680,height=4320 ! \
vaapivp9enc ! fakesink
will crash.

We need the allowed_profiles to store the allowed profiles in down
stream's caps.
Command line like:
vaapivp9enc ! capsfilter caps=video/x-vp9,profile="{ (string)1, \
(string)3 }"
We need to store GST_VAAPI_PROFILE_VP9_1 and GST_VAAPI_PROFILE_VP9_3
in this list.

Some profile, such as H265_MAIN_444 on new Intel platform, may only
support ENTRYPOINT_SLICE_ENCODE_LP entrypoint. This leads two
problems:
1. We need to specify the tune mode like `vaapih265enc tune=low-power`
every time when we need to use this kind of profile. Or we can not
create the encoder context successfully.
2. More seriously, we set the entrypoint to a fixed value in
init_context_info() and so the create_test_context_config() can not
create the test context for these profile and can not get the
supported video formats, either.
We now change the entrypoint setting based on the tune option of the
encoder. If no tune property provided, we just choose the first
available entrypoint.
Instead of init_context_info() setting the passed profile, it is
assumed that it has to be set by each encoder.

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

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.
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 vp9 encoder 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.
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.
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 input frame's formate changes, vp{8,9} encoders don't reset their frame
counter, hence the newly created frame could become a P-frame, leading to some
major troubles (sigabrt in libdrm in case of vp9). This patch adds some frame
prediction-related reset logic to the `flush' methods of GstVaapiEncoderVP8 and
GstVaapiEncoderVP9 implementations.
This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:
The encoding quality could be set through this structure, if the
implementation supports multiple quality levels. The quality level set
through this structure is persistent over the entire coded sequence, or
until a new structure is being sent. The quality level range can be queried
through the VAConfigAttribEncQualityRange attribute. A lower value means
higher quality, and a value of 1 represents the highest quality. The quality
level setting is used as a trade-off between quality and speed/power
consumption, with higher quality corresponds to lower speed and higher power
consumption.
The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.
Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".
All the available codecs now process this parameter if it is available.

While doing the mode-1 referece picture selection,
the circular buffer logic was not correctly setting the
refresh frame flags as per VP9 spec.
Make sure refresh_flag[0] get updated correclty after
each cycle of GST_VP9_REF_FRAMES.
https://bugzilla.gnome.org/show_bug.cgi?id=771507
Added two modes(as properties) for reference picture selection:
ref-mode-0: AltRef and GoldRef pointing to the recent keyframe
and LastRef is pointing to the previous frame.
ref-mode-1: Previous frame (n) as LastRef , n-1 th frame as GoldRef
and n-2 th frame as AltRef
