If the decoder has crop_top/left value > 0(e.g. the conformance
window in the H265). Which means that the real output picture
locates in the middle of the decoded buffer. If the downstream can
support VideoCropMeta, a VideoCropMeta is added to notify the
real picture's coordinate and size. But if not, we need to copy
it manually and the other_pool is needed. We always assume that
decoded picture starts from top-left corner, and so there is no
need to do this if crop_bottom/right value > 0.

The base va decoder's video_align is just used for calculation the
real decoded buffer's width and height. It does not have meaning
for the VideoMeta, because it does not align to the real picture
in the output buffer. We will use VideoCropMeta to replace it later.

The base va decoder's video_align is just used for calculation the
real decoded buffer's width and height. While the gst_video_info_align
just calculate the offset and stride based on the video_align. But
all the offsets and strides are overwritten in gst_va_dmabuf_allocator_try
or gst_va_allocator_try, which make that calculation useless.

We add 12 bits entries into this default mapping. And the old mapping
is not precise. For example, the NV12 should not be used as the default
mapping for VA_RT_FORMAT_YUV422 and VA_RT_FORMAT_YUV444, it is even not
a 422 or 444 format.

We already declare the support of HEVC screen content extension profiles
in the profile mapping list, but we fail to generate the correct VA picture
parameters buffers. This may cause the GPU hang.
We need to fill the buffer of VAPictureParameterBufferHEVCExtension correctly.

The function of gst_h265_get_profile_from_sps() is better than the
function gst_h265_profile_tier_level_get_profile() when we recognize
the profile of the stream, becaue it considers the compatibility.
It is also used by h265parse to recognize the profile. So it is
better to keep the same behaviour with the parse and other decoders.

VA-API HEVC decoding needs to known which is the last slice of a
picture, but slices are processed sequencially, so we know the
last slice until all the slices are already pushed into the
VABuffer array.
In order to mark the last slice, they are pushed into the
VABuffer array with a delay of one slice: the first slice is
hold, and when the second slice come, the first one is pushed
while holding the second, and so on. Finally, at end_picture(),
the last slice is marked and pushed into the array.

The VA acceleration now has more usages in linux-like platforms,
such as the MSDK. The different plugins based on the VA acceleration
need to share some common logic and types. We now move the display
related functions and types into a common va lib.

We have only one copy of gst_va_base_dec_parent_class inside the
vabasedec, so it can not handle the case when there are multi va
decoders inside one pipeline. The pipeline:
gst-launch-1.0 filesrc location=xxx.h264 ! h264parse \
! vah264dec ! msdkh265enc ! vah265dec ! fakesink
generates a assertion of
"invalid cast from 'GstVaH264Dec' to 'GstH265Decoder"
and gets a crash.
We should keep the parent_class for each decoder type.

VADecPictureParameterBufferAV1.mode_control_fields.bits were filled
twice, overwriting to zeros the first assignation. This patch unifies
both assignations.
Also it makes explicit an enum casting between libva and gstreamer; it
removes the assignation to zero a deprecated parameter; and use an
appropriate assertion.

The problem is for uploading YUV frames using derived images, is that
derived images imply tiling, so frames are wrongly uploaded.
Though derived for reading might work we cannot know the Intel graphics
generation to validate the caching. Overall, it's safer to disable derived
images for i965.

iHD driver sets a tiled DRM modifier if surface's usage hint is set to
VPP_WRITE. This result in a garbled rendering when using glimagesink.
This patch changes the usage hint to generic if the caps feature is
DMABuf. Either way only iHD driver, so far, uses the usage hint flag.

Implementation of mem_copy() virtual method for GstVaAllocator.
It's a deep copy where a new VA memory is popped out from the pool or,
if pool is empty, a new memory is allocated. The original memory is
mapped to read, and if its VAImage is not derived and size to copy is
the whole surface, the mapped VAImage of the original memory is put in
the new memory. Otherwise a slow memcpy is done between both memories.

Different VA drives might have different definitions for RGB32 color
formats because different bit interpretation. Sadly the specification
doesn't clarify these interpretations. So VA users have to figure out
what's the correct mapping with it's rendering color format
definition.
This patch aims to fix the static map structure after the
VAImageFormats are queried. There is another static map with the
different interpretations of the RGB32 formats, and compare them with
the given VAImageFormat, then with the GStreamer color format, update
the mapping table.
Finally, some RGB32 color formats were added.

vapostproc tries to be in passthrough mode as much as possible. But
they might be situations where the user might force to process the
frames. For example, when upstream sets the crop meta and the user
wants VA do that cropping, rather than downstream.
For those situations this property will disable the passthrough mode,
if it's enabled.

If incoming buffers have crop meta it's done by vapostproc, iif
vapostproc is not in passthrough mode and downstream doesn't handle
it.
This patch announces the crop meta API in proposed bufferpool, while
it stops filtering meta APIs, since it was only filter crop api.
Also if downstream supports crop and video metas, vapostporoc
announces both meta APIs in upstream bufferpool.
Finally, the meta is removed from the buffer if the crop is enabled.

This new struct describes the input and output GstBuffers to
post-process, including VA flags. It also contains the VASurfaceID and
VARectangle, but those are private, completed inside GstVaFilter.
It is used for pass arguments to gst_va_filter_convert_surface() function.

When an input buffer needs to be copied into a VA memory, it's
required to create a buffer pool. This patch uses the
propose_allocation() caps to instantiate the allocator and pool,
instead of the negotiated caps, which rather represents the resolution
to display.

Derived images are direct maps to surfaces bits, but in Intel Gen7 to
Gen9, that memory is not cachable, thus reading can be very slow (it
might produce timeout is tests such as fluster).
This patch tries first to define if derived images are possible, and
later use them only if mapping is not for reading.

This plugin, for decoders more concretely, assumes that a VA config
can do certain color conversions when mapping frames onto CPU's
memory.
This assumption was valid for i965 and Gallium drivers which generates
valid outputs in bitstreams testers (v.gr. fluster). Nonetheless, iHD,
even when it generates acceptable rendered frames, output's MD5 of
tests weren't valid.
This patch append the image formats, for color conversion when mapping
to memory, for non-iHD drivers.

After the VA filter creation, when changing the element's state from NULL
to READY, immediatly checks for any filter operation requested by the user.
If any, the passthrough mode is disabled early, so there's no need for a
future renegotiation.

When we transform the caps from the sink to src, or vice versa, the
"caps" passed to us may only contain parts of the features. Which
makes our vpp lose some feature in caps and get a negotiation error.
The correct way should be:
Cleaning the format and resolution of that caps, but adding all VA,
DMA features to it, making it a full feature caps. Then, clipping it
with the pad template.
fixes: #1551
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2081>
Added helper function _update_passthrough() which will define and set
the pass-through mode of the filter, and it'll either reconfigure both
pads or it will just mark the src pad for renegotiation or nothing at
all.
There are cases where both pads have to be reconfigured (direction
changed, for example), other when just src pad has to (filters
updated) or none (changing to ready state).
The requirement of renegotiation depends on the need to enable/disable
its VA buffer pools.
This patch sets pass-through mode by default, so the buffer pools
aren't allocated if no filtering/direction operations are defined,
which is the correct behavior.
