When baseline-as-constrained is set, the decoder will expose support
for baseline decoding and assume that the baseline content is
constrained-baseline. This can be handy to decode streams in hardware
that would otherwise not be possible to decode. A lot of baseline
content is in fact constrained.
We do not need to maintain a standalone list of decoder's output
template for raw formats and that is easy to make mistake(for
example, the AYVU is wrong in that list, should be VUYA).
Just use GST_VAAPI_FORMATS_ALL to replace the raw formats list for
src template.
When the code path goes to push buffers downstream when no surface
available in decoder context, and it fails the code bails out with a
fatal error.
That behavior is wrong, since it shouldn't be fatal. The use case is
when the video stream is disabled.
This patch just ignores the errors in this situation and demotes the
level of a log message.
For surfaces with different chroma type, it is prefer to initialize
a format which chroma type should be same with surface chroma type
instead of using fixed NV12.
When create vaapi surface, it is better to use the chroma type get
from jpeg file instead of using fixed 420 format. And the correct
chroma type can be determined by horizontal_factor/vertical_factor
flags that get from jpegparse.
The gst_vaapi_plugin_base_get_allowed_raw_caps is used for both sink
pad and src pad, which cause some bugs. For sink pad, we need to verify
vaPutImage() while for the src pad we need to verify vaGetImage().
For vaapidecoderXXX kind of plugins, the case is more complex. We need
to verify whether the decoded result(in some surface, NV12 format most
of the time) can be vaGetImage to some raw image format. Add more check
to fix all these problems.

Add 444 10bit yuv format Y410, which can be used to decode
main-444 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.
Add 422 10bit yuv format Y210, which can be used to decode
main-10-422 10bit streams. Currently, this feature is only
supported by media-driver in Icelake.

If the unit could not be parsed, just skip this nal and keep parsing
what is left in the adapter. We need to flush the broken unit in the
decoder specific parser because the generic code does not know about
units boundary. This increases error resilliance.
Before this, the broken unit would stay in the adapter and EOS would be
returned. Which stopped the streaming. Just removing the EOS would have
lead to the adapter size growing indefinitely.

Generate system allocated output buffers when downstream doesn't
support GstVideoMeta.
The VA buffer content is copied to the new output buffer, and it
replaces the VA buffer.

Coverity scan bug:
The variable will contain an arbitrary value left from earlier
computations.
Variable base_only is fetched from base-only property, and it may be
not assigned. It needs to be initialized.
Clear decoders out on a flush but keep the same instance,
rather than completely recreating them. That avoids
unecessarily freeing and recreating surface pools
and contexts, which can be quite expensive

As in gstreamer-vaapi a common base class is used, the specific
default category is passed to the base-plugin initializator, thus
the log messages are categorized with the used plugin.
Nonetheless, when the gst-debug is disabled in compilation time,
it is needed to pass NULL to the base-plugin initializator. This
patch does that.

Rename to be consistent with H.264 and also H.265 encoder. The
meson build assumed this was already consistently named, and so
previously was not able to actually build the H.265 decoder.

Use new -base API gst_video_decoder_allocate_output_frame_full() to
pass the current proxy/surface to the pool.
The pool will will export thins given surface instead of exporting a
brand new surface that will never be filled in with meaningfull data.

When a new sink caps arrive the internal decoder state is updated
and, if it is, request a downstream renegotiation.
Previously, when new caps arrived the whole decoder where destroyed
and recreated. Now, if the caps are compatible or has the same codec,
the internal decoder is kept, but a downstream renegotiation is
requested.

This reverts commit 3285121181.
videodecode's negotiate() vmethod is also called when events arrive,
but this would mean that the proper configuration of sink pad might
not be complete, thus we should not update the src pad.
Let's keep the old non-vmethod negotitate().
Since the differentiation of negotiation caps and allocation caps,
there is no need to add a video crop meta with the negotiation caps.
Hence, removing it.

This is related with bug 758907 when no vaapipostproc is used (no
vaapidecodebin). In order to negotiate downstream we need to destroy
the source pad allocator, otherwise the same allocated buffers are
used, failing the mapping.
The variable member allowed_sinkpad_caps is constructed querying the
current VA display. Bearing that in mind, the variable shall be freed
when the VA display changes or is removed.
This patch moves the freeing of allowed_sinkpad_caps to close(), when
the VA display is freed.
