45732dcc83 encoder: h264: clean-ups.
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.

0c5f69e0d9 encoder: mpeg2: 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.

e311d53c8a encoder: mpeg2: 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. Improve lookup for
the best suitable level with the new MPEG-2 helper functions.

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

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.

368caf22da encoder: fix bitrate units to match kbps.
Bitrate is expressed in kilobits per second (kbps). So, this exactly
means in multiple of 1000 bits, not 1024 bits.

850a637d0f encoder: filter out the supported set of rate-control properties.
Only expose the exact static set of supported rate-control properties
to the upper layer. For instance, if the GstVaapiEncoderXXX class does
only support CQP rate control, then only add it the the exposed enum
type.

Add helper macros and functions to build a GType for an enum subset.

59229b20a5 encoder: add keyframe period API.
Add gst_vaapi_encoder_set_keyframe_period() interface to allow the
user control the maximum distance between two keyframes. This new
property can only be set prior to gst_vaapi_encoder_set_codec_state().

A value of zero for "keyframe-period" gets it re-evaluated to the
actual framerate during encoder reconfiguration.

8788ea99a8 encoder: improve codec reconfiguration.
Improve codec reconfiguration to be performed only through a single
function. That is, remove the _set_context_info() hook as subclass
should not alter the parent GstVaapiContextInfo itself. Besides, the
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.

70b3600f11 encoder: add bitrate API.
Add gst_vaapi_encoder_set_bitrate() interface to allow the user control
the bitrate for encoding. Currently, changing this parameter is only
valid before the first frame is encoded. Should the value be modified
afterwards, then GST_VAAPI_ENCODER_STATUS_ERROR_OPERATION_FAILED is
returned.

error ("operation-failed") is issued.

1dd89800b0 decoder: h264: fix decoding of BA3_SVA_C.264.
Conformance test Base_Ext_Main_profiles/BA3_SVA_C.264 complys with
extended profile specifications. However, the SPS header has the
constraint_set1_flag syntax element set to 1. This means that, if
a Main profile compliant decoder is available, then it should be
able to decode this stream.

This changes makes it possible to fall-back from Extended profile
to Main profile if constraint_set1_flag is set to 1.

2940a74ea4 encoder: fix computation of max coded buffer size (again).
The previous fix was only valid to express the maximum size of the
macroblock layer, i.e. without any headers. Now, also account for
the slice headers and top picture header, but also any other header
we might stuff into the VA coded buffer, e.g. sequence headers.

b864d1f71a encoder: fix computation of max coded buffer size.
Fix coded buffer size for each codec. A generic issue was that the
number of macroblocks was incorrectly computed. The second issue was
specific to MPEG-2 were the max number of bits per macroblock, and
as defined by the standard, was incorrectly mapped to the (lower)
H.264 requirement. i.e. 4608 bits vs. 3200 bits limit.

fd9c855f14 encoder: simplify VA context initialization process.
Change get_context_info() into a set_context_info() function that
initializes common defaults into the base class, thus allowing the
subclasses to specialize the context info further on.

The set_context_info() hook is also the location where additional
context specific data could be initialized. At this point, we are
guaranteed to have valid video resolution size and framerate. i.e.
gst_vaapi_encoder_set_format() was called beforehand.
