Add interface to communicate configurable properties to the encoder.
This covers both the common ones (rate-control, bitrate), and the
codec specific properties.
https://bugzilla.gnome.org/show_bug.cgi?id=719529
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.
https://bugzilla.gnome.org/show_bug.cgi?id=719529
Add gst_vaapi_encoder_set_rate_control() interface to request a new
rate control mode for encoding. Changing the rate control mode is
only valid prior to encoding the very first frame. Afterwards, an
error ("operation-failed") is issued.

Instal <gst/vaapi/gstvaapiutils_h264.h> header but only expose the
H.264 levels in there. The additional helper functions are meant
to be private for now.
Fix formts for various GST_DEBUG et al. invocations. More precisely,
make size_t arguments use the %zu format specifier accordingly; force
XID formats to be a 32-bit unsigned integer; and fix the format used
for gst_vaapi_create_surface_with_format() error cases since we have
been using strings nowadays.
The following helper functions are no longer used, thus are removed:
- gst_vaapi_video_format_from_structure()
- gst_vaapi_video_format_from_caps()
- gst_vaapi_video_format_to_caps()
Replace gst_vaapi_display_get_{decode,encode}_caps() APIs with more
more convenient APIs that return an array of GstVaapiProfile instead
of GstCaps: gst_vaapi_display_get_{decode,encode}_profiles().
Replace gst_vaapi_display_get_{image,subpicture}_caps() APIs, that
returned GstCaps, with more convenient APIs that return an array of
GstVideoFormat: gst_vaapi_display_get_{image,subpicture}_formats().
Fix display creation code to check that any display obtained from a
neighbour actually has the type we expect. Note: if display type is
set to "any", we can then accept any VA display type.
The GLTextureUploadMeta implementation assumed that for each upload()
sequence, the supplied texture id is always the same as the one that
was previously cached into the underlying GstVaapiTexture. Cope with
any texture id change the expense to recreate the underlying VA/GLX
resources.

Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode
a picture if there was no valid frame headers parsed so far.
https://bugs.freedesktop.org/show_bug.cgi?id=57902
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.
https://bugzilla.gnome.org/show_bug.cgi?id=720190
Recognize streams marked as conforming to the "Constrained Baseline
Profile". If VA driver supports that as is, fine. Otherwise, fallback
to baseline, main or high profile.
Constrained Baseline Profile conveys coding tools that are common
to baseline profile and main profile.

[Added fallbacks to main and high profiles]

The GStreamer codecparser layer now parses the scaling lists in zigzag
scan order, as expected, so that to match the original bitstream layout
and specification. However, further convert the scaling lists into
raster scan order to fit the existing practice in most VA drivers.

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.
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.
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.
Clean public APIs up so that to better align with the decoder APIs.
Most importantly, gst_vaapi_encoder_get_buffer() is changed to only
return the VA coded buffer proxy. Also provide useful documentation
for the public APIs.
Kill GstVaapiEncoderSyncPic objects that are internally and temporarily
allocated. Rather, associate a GstVaapiEncPicture to a coded buffer
through GstVaapiCodedBufferProxy user-data facility.
Besides, use a GAsyncQueue to maintain a thread-safe queue object of
coded buffers.
Partial fix for the following report:
https://bugzilla.gnome.org/show_bug.cgi?id=719530
Fix the GstVaapiEncoderClass parent class type. Make sure to validate
subclass hooks as early as possible, i.e. in gst_vaapi_encoder_init(),
thus avoiding useless run-time checks. Also simplify the subclass
initialization process to be less error prone.
Refactor the GstVaapiCodedBuffer APIs so that to more clearly separate
public and private interfaces. Besides, the map/unmap APIs should not
be exposed as is but appropriate accessors should be provided instead.
* GstVaapiCodedBuffer: VA coded buffer abstraction
- gst_vaapi_coded_buffer_get_size(): get coded buffer size.
- gst_vaapi_coded_buffer_copy_into(): copy coded buffer into GstBuffer
* GstVaapiCodedBufferPool: pool of VA coded buffer objects
- gst_vaapi_coded_buffer_pool_new(): create a pool of coded buffers of
the specified max size, and bound to the supplied encoder
* GstVaapiCodedBufferProxy: pool-allocated VA coded buffer object proxy
- gst_vaapi_coded_buffer_proxy_new_from_pool(): create coded buf from pool
- gst_vaapi_coded_buffer_proxy_get_buffer(): get underlying coded buffer
- gst_vaapi_coded_buffer_proxy_get_buffer_size(): get coded buffer size
Rationale: more optimized transfer functions might be provided in the
future, thus rendering the map/unmap mechanism obsolete or sub-optimal.
https://bugzilla.gnome.org/show_bug.cgi?id=719775
Add gst_vaapi_surface_proxy_copy() function that creates a new surface
proxy with the same information from the parent proxy, except that the
user-defined destroy notify function is not copied over.
The underlying VA surface is pushed back to the video pool only when
the last reference to the parent surface proxy is released.
Optimize gst_vaapiencode_handle_frame() to avoid extra memory allocation,
and in particular the GstVaapiEncObjUserData object. i.e. directly use
the VA surface proxy from the source buffer. This also makes the user
data attached to the GstVideoCodecFrame more consistent between both
the decoder and encoder plug-in elements.
Add gst_buffer_new_allocate() and gst_buffer_fill() implementations.
Fix gst_buffer_new_wrapped_full() implementation to handle the destroy
notify function.
Add initial API for video encoding: only basic interfaces and small
encoder objects are implemented so far.
