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
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.

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

the buffer listener callbacks 'release', without calling previously

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

removed, since proxy object is deleted when wayland server sees the

We need to call roundtrip before destroying event_queue so that the
proxy object is removed. Otherwise, it would be mess up as receiving

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.
https://bugzilla.gnome.org/show_bug.cgi?id=771291
