If the picture is IDR, also submit a SPS header.
This means when frame number reaches to keyframe-period or an force
key unit event arrives, we insert SPS/PPS again.

GST_VIDEO_CODEC_FRAME_IS_FORCE_KEYFRAME() is a flag usually used to manage
the `frame-lost` event in the case of streaming, such as RTP.
In case of this event, it is needed to start new GOP rather than just
produce an I-frame.

Insert an AUD as the first NAL of each encoded frame.
Some applications require Access Unit Delimiter for decoding the
stream.
The AU delimeter insertion is done only when the aud parameter is
TRUE (by default is disabled). The reason of this it is because this
header is only available from Intel Gen9 and the VA intel driver
should be 1.8 or superior. Otherwise, the output will be corrupted.

Currently when num_views is changed by multiview-mode on sink caps, it produces
wrong MVC encoded stream since the array view_ids is not set properly according
to changed num_views.
So this patch initializes all of the array sequentially to handle this case.
Side effect is not going to happen by this patch since this array is being
handled by num_views.

Until now, the encoder ignored the profile in src caps and chose one
according with the given parameters. But the encoder must honor the
profile specifed in src caps.
This patch do that, and if the encoder needs to choose the profile,
it will do it by following these rules:
1\ If given parameters are not compatible with given profile, the
encoder will bail out with an error.
2\ The encoder will choose the higher profile indicated in the
src caps.

Since commits in https://bugzilla.gnome.org/show_bug.cgi?id=781142 landed,
they introduced regression in seek.
Formerly, once seek is done, decoder drops P-frames until I-frame arrives.
But since the commits landed, it doesn't drop P-frame and does try to
decode it continuously because active_sps is still alive. See ensure_sps function.
But there are prev_frames and prev_ref_frames reset already, then it
causes assertion.
So it's necessary to reset active_sps/pps also in reset method.

Change the hard-coded range of quality-level from {1-8} to {1-7},
since it is the range Intel Open source driver supports.
Also perform the range clamping only if the user provided
quality-level is greater than the max-range suppored by the driver,
because there could be non-intel drivers giving lower value than
the hard-coded max value 7.

Instead of recalculating the miscellaneous buffer parameters for
every buffer, it is only done once, when the encoder is configured.
And for every buffer, the same structures are just copied.

This is patch pretends to decouple the assignation of the values
in the parameter structures and the VA buffer's parameters setting.
It may lead to some issues since HRD, framerate or controlrate may
not be handled by the specific encoder, but they are set in
the VA buffer's parameters.
I leave as it because this patch is just a transitional patch.

According to the VA documentation:
The framerate is specified as a number of frames per second,
as a fraction. The denominator of the fraction is given in
the top half (the high two bytes) of the framerate field, and
the numerator is given in the bottom half (the low two bytes).
For example, if framerate is set to (100 << 16 | 750), this is
750 / 100, hence 7.5fps.
If the denominator is zero (the high two bytes are both zero)
then it takes the value one instead, so the framerate is just
the integer in the low 2 bytes.
This patch fixes the the framerate calculation in vp8 encoder
according to this.

Instead of using a proxy to story the buffer quality level, the
encoder now uses the native VA structure, which is copied to the
dynamically allocated VAEncMiscParameterBuffer.
This approach is computationally less expensive.
Right now, H264 and HEVC can set as a property the number of slices to
process. But each driver can set a maximum number of slices, depending
on the supported profile & entry point.
This patch verifies the current num_slices to process against the maximum
permitted by the driver and the media size.

Since we started using VPP in VaapiWindowX11, we need to care about
the case that src rect and window's size are different.
So, once VPP has converted to other format, we should honor the
size of the VPP's surface as source rect. Otherwise, it is cropped
according the previous size of the source rect.

Queries if the driver supports "Region of Interest" (ROI) during the config
creation.
This attribute conveys whether the driver supports region-of-interest (ROI)
encoding, based on user provided ROI rectangles. The attribute value is
partitioned into fields as defined in the VAConfigAttribValEncROI union.
If ROI encoding is supported, the ROI information is passed to the driver
using VAEncMiscParameterTypeROI.

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.

Sometimes gst_vaapi_window_wayland_sync returns FALSE when poll returns EBUSY
during destruction.
In this case, if GstVaapiWindow is using vpp, leak of vpp surface happens.
This surface is not attached to anything at this moment, so we should release
it manually.

When the frame listener callbacks 'done', the number of pending
frames are decreased. Nonetheless, there might be occasions where
the buffer listener callbacks 'release', without calling previously
frame's 'done'. This leads to problem with
gst_vaapi_window_wayland_sync() operation.
This patch marks as done those frames which were callbacked, but if
the buffer callbacks 'release' and associated frame is not marked
as 'done' it is so, thus the number of pending frames keeps correct.

Don't call gst_vaapi_window_wayland_sync() when destroying the
wayland window instance, since it might lead to a lock at
gst_poll_wait() when more than one instances of vaapisink are
rendering in the same pipeline, this is because they share the
same window.
Since now all the frames are freed we don't need to freed the
private last_frame, since its address is invalid now.

Fix leakage of the last wl buffer.
VAAPI wayland sink needs to send a null buffer while destruction,
it assures that all the wl buffers are released. Otherwise, the last
buffer's callback might be not called, which leads to leak of
GstVaapiDisplay.
This was inspired by gstwaylandsink.

The proxy object of wl_buffer for the last frame remains in the
wl_map. Even though we call wl_buffer_destroy() in
frame_release_callback(), the proxy object remains without being
removed, since proxy object is deleted when wayland server sees the
delete request and sends 'delete_id' event.
We need to call roundtrip before destroying event_queue so that the
proxy object is removed. Otherwise, it would be mess up as receiving
'delete_id' event from previous play, when playing in the next
va/wayland window with the same wl_display connection.
