c5581298fb display: don't use GstCaps for decode or encode profiles list.
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().

61f6cbffc6 plugins: fix GLTextureUploadMeta to work with different texture ids.
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.

6fe54964bb h264: improve robustness when packets are missing.
Improve robustness when some expected packets where not received yet
or that were not correctly decoded. For example, don't try to decode

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.

009e4522bf decoder: h264: add support for constrained baseline profile.
Recognize streams marked as conforming to the "Constrained Baseline

bd5ae1b220 decoder: h264: fix decoding of scaling lists.
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.

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.

26726b18fc encoder: avoid extra allocations of GstVaapiEncoderSyncPic objects.
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.

0fb7c60508 encoder: rework GstVaapiCodedBuffer and related proxy.
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.
