99947d0592 libs: add generic bitstream writer.
GstBitWriter provides a bit writer that can write any number of bits
to a pre-allocated memory buffer. Helper functions are also provided
to write any number of bits from 8, 16, 32 and 64 bit variables.

Extend GstVaapiContextInfo structure to hold the desired rate control
mode for encoding purposes. For decoding purposes, this field is not
used and it is initialized to GST_VAAPI_RATECONTROL_NONE.

Fix build when Wayland headers don't live in plain system include dirs

7a464ba015 vaapipostproc: fix and optimize advanced deinterlacing mode.
Fix advanced deinterlacing modes with VPP to track only up to 2 past
reference buffers. This used to be 3 past reference buffers but this
doesn't fit with the existing decode pipeline that only has 4 extra
scratch surfaces.

Also optimize references tracking to be only enabled when needed, i.e.
when advanced deinterlacing mode is used. This means that we don't
need to track past references for basic bob or weave deinterlacing.

1d1f18bcbe vaapipostproc: fix "mixed" mode deinterlacing.
In "mixed" interlaced streams, the buffer contains additional flags that
specify whether the frame contained herein is interlaced or not. This means
that we can alternatively get progressive or interlaced frames. Make sure
to disable deinterlacing at the VPP level when the source buffer is no longer
interlaced.

this happens when the correct set of expected caps are being exposed.
This means that, currently, the proposed caps are not fully accurate.

a3af786c78 vaapipostproc: fix transform caps.
Fix GstBaseTransform::transform_caps() implementation to always return
the complete set of allowed sink pad caps (unfixated) even if the src
pad caps we are getting are fixated. Rationale: there are just so many
possible combinations, and it was wrong to provide a unique set anyway.

As a side effect, this greatly simplifies the ability to derive src pad
caps from fixated sink pad caps.

06c7fde8e0 filter: fix semantics of deinterlacing flags.
Fix deinterlacing flags to make more sense. The TFF (top-field-first)
flag is meant to specify the organization of reference frames used in
advanced deinterlacing modes. Introduce the more explicit flag TOPFIELD
to specify that the top-field of the supplied input surface is to be
used for deinterlacing. Conversely, if not set, this means that the
bottom field of the supplied input surface will be used instead.

a6436f27d5 vaapidecode: fix decoder flush.
There are situations where gst_video_decoder_flush() is called, and
this subsequently produces a gst_video_decoder_reset() that kills the
currently active GstVideoCodecFrame. This means that it no longer
exists by the time we reach GstVideoDecoder::finish() callback, thus
possibly resulting in a crash if we assumed spare data was still
available for decode (current_frame_size > 0).

Try to honour GstVideoDecoder::reset() behaviour from GStreamer 1.0
that means a flush, thus performing the actual operations there like
calling gst_video_decoder_have_frame() if pending data is available.

367944ba32 vaapidecode: drop decode timeout, always wait for a free surface.
vaapidecode used to wait up to one second past the expected time of
presentation for the last decoded frame. This is not realistic in
practice when it comes to video pause/resume. Changed behaviour to
unconditionnally wait for a free VA surface prior to continuing the
decoding. The decode task will continue pushing the output frames to
the downstream element while also reporting errors at the same time
to the main thread.

7e8470e1ec vaapidecode: fix srcpad caps for GStreamer 1.2.
The srcpad caps exposed for GStreamer 1.2 were missing any useful info
like framerate, pixel-aspect-ratio, interlace-mode et al. Not to mention
that it relied on possibly un-initialized data. Fix srcpad caps to be
initialized from a sanitized copy of GstVideoDecoder output state caps.

Note: the correct way to expose the srcpad caps triggers an additional
issue in core GStreamer auto-plugging capabilities as the correct caps
to be exposed should be format=ENCODED with memory:VASurface caps feature
at the minimum. In some situations, we could determine the underlying
VA surface format, but this is not always possible. e.g. cases where it
is not allowed to expose the underlying VA surface data, or when the
VA driver implementation cannot actually provide such information.

d556c0a37a plugins: streamline VA formats exposed in caps to a realistic set.
Currently, the decoder only supports YUV 4:2:0 output. So, expose the
output formats for GStreamer 1.2 in caps to a realistic subset. This
means NV12, I420 or YV12 but also ENCODED if we cannot determine the
underlying VA surface format, or if it is actually not allowed to get
access to the surface contents.

b62bd57bda vaapipostproc: fix support for raw YUV data upload on GStreamer 1.0.
Fix raw YUV data uploaded as in the following pipeline:
$ gst-launch-1.0 filesrc video.yuv ! videoparse ! vaapipostproc ! vaapisink

The main reason why it failed was that the videoparse element simply
allocates GstBuffer with raw data chunk'ed off the sink pad without
any prior knowledge of the actual frame info. i.e. it basically just
calls gst_adapter_take_buffer().

We could avoid the extra copy performed in vaapipostproc if the videoparse
element was aware of the downstream pool and bothers copying line by
line, for each plane. This means that, for a single frame per buffer,
the optimizatin will be to allocate the video buffer downstream, map
it, and copy each line that is coming through until we need to fills
in the successive planes.

Still, optimized raw YUV uploads already worked with the following:
$ gst-launch-1.0 videotestsrc ! vaapipostproc ! vaapisink
