Similarly to previous patch, we have no error concealment. As a side
effect, it's better to skip slices with missing references then passing

Usually in case of MVC decoding, dpb size is increasedi if subset sps.

Otherwise, it leads to assert.

If the unit could not be parsed, just skip this nal and keep parsing
what is left in the adapter. We need to flush the broken unit in the
decoder specific parser because the generic code does not know about
units boundary. This increases error resilliance.
Before this, the broken unit would stay in the adapter and EOS would be
returned. Which stopped the streaming. Just removing the EOS would have
lead to the adapter size growing indefinitely.

2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.
Also this patch includes:
- Set num_negative_pics and num_positive_pics according to the number of

first for the ENC only and the second for PAK only.
Each mode associated with separate context ,but same pool of surfaces are
shared between the modes.
This is more useful once we have custom BRC algorithms.

So treating them as a part of CodedBufferProxy too.

There are 6 new va buffer types, each defined as a specific codec object.
Borrowed the code from gstvaapicodecobject , but made a clear separation
to avoid any possible mess-up. Because unlike the other gstvaaicodecobjects,
feicodecobjects can be shared between elements and also can be accessed
from different thread.
Unlike the other fei codecs object, VAEncMiscParameterTypeFEIFrameControl
object is not shared between elements.So we utilize the already
existing gst_vaapi_enc_misc_param_new(), but still keeping the code
in gstvaapfei_objects_priv.h in order to have a better
code readability.
Fixme:
-- Probably we need _locked_map() and _unlocked_map()
-- Context can be associated with PreEnc(not just Enoder)
once we have the proper support inplace, but for now we don't have
PreEnc support, so should be safe enough to use GstVaapiEncoder.

Drops non-base NALs when the base-only property is set to TRUE.
This modifies the behavior for MVC streams with base-only too: All the
non-base units are dropped before they are decoded instead of dropping
the non-base frames.
The relevant part from the H264 spec is:
> Decoders that conform to one or more of the profiles specified in
Annex A rather than the profiles specified in Annexes G or H shall
ignore (remove from the bitstream and discard) the contents of all NAL
units with nal_unit_type equal to 14, 15, or 20.
To eliminate side effects from the offending units:
- PPS's with a broken seq_parameter_set_id (referring to dropped subset
SPS's) are ignored.
- The NAL parsing is skipped and their flags are set to
GST_VAAPI_DECODER_UNIT_FLAG_SKIP.
- Prefix units are not stored in prev_pi. Otherwise, parse_slice() would
use them even if they are flagged to be skipped. Subset SPS's and slice
extension units are not stored there either.

Using num_ref_frames provided and the result of the Query
VAConfigAttribEncMaxRefFrames, it determines the size of reference list
and perform encoding with multi reference frames as the following:
1\ The num_ref_frames is being considered as the number of
reference picture list0
2\ Encoder adds 1 reference frame more to the reference picture list1
internally if b-frame encoding.
3\ If num_ref_frames is bigger than the number of refrence frames
supported in the driver, it will be lowered.
https://bugzilla.gnome.org/show_bug.cgi?id=783803
Users can provide the number of reference frame by this property.
The value of the property will be considered as the number of
reference picture list0 and will add 1 reference frame more to the
reference picture list1 internally if b-frame encoding.
If the value provided is bigger than the number of refrence frames
supported in the driver, it will be lowered.
https://bugzilla.gnome.org/show_bug.cgi?id=783803
This function will query VAConfigAttribEncMaxRefFrames to get the
maximum number of reference frames supported in the driver.
This will be used for h264/h265 encoding.

Added a new property "compliance-mode", which default is the normal
strict compliant mode.
The second mode, "restrict-buf-alloc", is to limit the coded buffer

encodings). Under this new mode, we use the MinCR field in A.3.1 for
pre-calculating the coded-buffer size.

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

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.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=783449
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.
https://bugzilla.gnome.org/show_bug.cgi?id=783449
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

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

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.

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.

When the function gst_vaapi_encoder_get_surface_formats() was added
it was under the assumption that any VA profile of the specific codec
supported the same format colors. But it is not, for example the
profiles that support 10bit formats.
In other words, different VA profiles of a same codec may support
different color formats in their upload surfaces.
In order to expose all the possible color formats, if no profile is
specified via source caps, or if the encoder doesn't have yet a
context, all the possible VA profiles for the specific codec are
iterated and their color formats are merged.
