c03682ecc1 encoder: re-order submission of VA objects.
Change the submission order of VA objects so that to make that process
more logical. i.e. submit sequence parameter first, if any; next the
packed headers associated to sequece, picture or slices; and finally
the actual picture and associated slices.

d45c6a486f encoder: clean-up objects.
Various clean-ups to improve consistency and readability: rename some
variables, drop unused macro definitions, drop initialization of vars
that are zero-initialized from the base class, drop un-necessary casts,
allocate GPtrArrays with a destroy function.

78bf2c01cc encoder: h264: fix frame cropping rectangle calculation.
Fix frame cropping rectangle calculation to handle horizontal resolutions
that don't match a multiple of 16 pixels, but also the vertical resolution
that was incorrectly computed for progressive sequences too.

c7a2095b78 encoder: h264: improve automatic bitrate calculation.
For non "Constant-QP" modes, we could provide more reasonable heuristics
for the target bitrate. In general, 48 bits per macroblock with all the
useful coding tools enable looks safe enough. Then, this rate is raised
by +10% to +15% for each coding tool that is disabled.

7b1233faa8 encoder: h264: support "high-compression" tuning option.
Add support for "high-compression" tuning option. First, determine the
largest supported profile by the hardware. Next, check any target limit
set by the user. Then, enable each individual coding tool based on the
resulting profile_idc value to use.

bdf91aa765 encoder: h264: allow target decoder constraints.
Allow user to precise the largest profile to use for encoding due
to target decoder constraints. For instance, if CABAC entropy coding
mode is requested by "constrained-baseline" profile only is desired,
then an error is returned during codec configuration.

Also make sure that the suitable profile we derived actually matches
what the HW can cope with.

00e0af9a7c encoder: h264: refine size of coded buffer.
Refine the heuristic to determine the maximum size of a coded buffer
to account for the exact number of slices. set_context_info() is the
last step during codec reconfiguration, no additional change is done
afterwards, so re-using the num_slices field here is fine.

- "dct8x8": enable spatial transform 8x8 (default: FALSE).

b59a5572af encoder: h264: derive profile and level from active coding tools.
Automatically derive the minimum profile and level to be used for
encoding, based on the activated coding tools. The encoder will
be trying to generate a bitstream that has the best chances to be
decoded on most platforms by default.

Also change the default profile to "constrained-baseline" so that
to ensure maximum compatibility when the stream is decoded.

2b482e8e4b encoder: h264: fix hardware profile lookup.
Fix lookup for a suitable HW profile, as to be used by the underlying
hardware, based on heuristics that lead to characterize the SW profile,
i.e. the one used by the SW level encoding logic.

Also fix constraint_set0_flag (A.2.1) and constraint_set1_flag (A.2.2)
as they should respectively match the baseline and main profile.

e2f8c059a5 encoder: h264: support only the byte-stream format.
The libgstvaapi core encoders are meant to support raw bitstreams only.
Henceforth, we are always producing a stream in "byte-stream" format.

However, the "codec-data" buffer which holds SPS and PPS headers is
always available. The "lengthSizeMinusOne" field is always set to 3
so that in-place "byte-stream" format to "avc" format conversion could
be performed.

21c95dbc42 encoder: add tuning options API.
Add encoder "tune" option to override the default behaviour that is to
favor maximum decoder compatibility at the expense of lower compression
ratios.

Expected tuning options to be developed are:
- "high-compression": improve compression, target best-in-class decoders;
- "low-latency": tune for low-latency decoding;
- "low-power": tune for encoding in low power / resources conditions.

user control the maximum distance between two keyframes. This new
property can only be set prior to gst_vaapi_encoder_set_codec_state().

actual framerate during encoder reconfiguration.

VA context is constructed only at the final stages of reconfigure().

5394c75461 encoder: add video codec-state API.
Add interface to communicate the encoder resolution and related info
like framerate, interlaced vs. progressive, etc. This new interface
supersedes gst_vaapi_encoder_set_format() and doesn't use any GstCaps
but rather use GstVideoCodecState.

Note that gst_vaapi_encoder_set_codec_state() is also a synchronization
point for codec config. This means that the encoder is reconfigured
there to match the latest properties.

2c4fde0eae vaapiencode: don't crash on NULL encoder on _finish().
Don't try to destroy an encoder, in GstVideoEncoder::finish() handler,
if it was not created in the first place. Return "not-negotiated" error
since this means we did not even reach GstVideoEncoder::set_format(),
where the encoder could have been created.

This fixes a crash when the vaapiencode_* plug-in elements get deallocated
and that we failed to negotiate either pad.

449ac54348 vaapiencode: fix negotiation process of output caps.
The specified caps in gst_video_encoder_set_output_state() function
arguments should not contain any resolution, pixel-aspect-ratio,
framerate, codec-data et al. Those rather should be set through the
returned GstVideoCodecState. This means that output caps creation
could be delayed until before gst_video_encoder_finish_frame() is
called.

This greatly simplifies the GstVideoEncoder::set_format() callback
by the way.

Besides, this also makes sure to not use or modify the GstVaapiEncoder
private definitions directly. Private data need to remain private.
