It returns a pointer inside the fifo's buffer, which cannot be safely
used without accessing AVFifoBuffer internals. It is easier and safer to
use av_fifo_generic_peek_at().

a428949775 avutils/hwcontext: When deriving a hwdevice, search for existing device in both directions
The test /libavutil/tests/hwdevice checks that when deriving a device
from a source device and then deriving back to the type of the source
device, the result is matching the original source device, i.e. the
derivation mechanism doesn't create a new device in this case.

Previously, this test was usually passed, but only due to two different
kind of flaws:

1. The test covers only a single level of derivation (and back)

It derives device Y from device X and then Y back to the type of X and
checks whether the result matches X.

What it doesn't check for, are longer chains of derivation like:

CUDA1 > OpenCL2 > CUDA3 and then back to OpenCL4

In that case, the second derivation returns the first device (CUDA3 ==
CUDA1), but when deriving OpenCL4, hwcontext.c was creating a new
OpenCL4 context instead of returning OpenCL2, because there was no link
from CUDA1 to OpenCL2 (only backwards from OpenCL2 to CUDA1)

If the test would check for two levels of derivation, it would have
failed.

This patch fixes those (yet untested) cases by introducing forward
references (derived_device) in addition to the existing back references
(source_device).

2. hwcontext_qsv didn't properly set the source_device

In case of QSV, hwcontext_qsv creates a source context internally
(vaapi, dxva2 or d3d11va) without calling av_hwdevice_ctx_create_derived
and without setting source_device.

This way, the hwcontext test ran successful, but what practically
happened, was that - for example - deriving vaapi from qsv didn't return
the original underlying vaapi device and a new one was created instead:
Exactly what the test is intended to detect and prevent. It just
couldn't do so, because the original device was hidden (= not set as the
source_device of the QSV device).

This patch properly makes these setting and fixes all derivation
scenarios.

(at a later stage, /libavutil/tests/hwdevice should be extended to check
longer derivation chains as well)

ed6c5c13b1 libavutil/hwcontext_qsv: clean padding when upload qsv frames
Fix #7830
When we upload a frame that is not padded as MSDK requires, we create a
new AVFrame to copy data. The frame's padding data is uninitialized so
it brings run to run problem. For example, If we run the following
command serveral times we will get different outputs.

ffmpeg -init_hw_device qsv=qsv:hw -qsv_device /dev/dri/renderD128 \
-filter_hw_device qsv -f rawvideo -s 192x200 -pix_fmt p010 \
-i 192x200_P010.yuv -vf "format=nv12,hwupload=extra_hw_frames=16" \
-c:v hevc_qsv output.265

According to https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/mediasdk-man.md#encoding-procedures
"Note: It is the application's responsibility to fill pixels outside
of crop window when it is smaller than frame to be encoded. Especially
in cases when crops are not aligned to minimum coding block size (16
for AVC, 8 for HEVC and VP9)"

I add a function to fill padding area with border pixel to fix this
run2run problem, and also move the new AVFrame to global structure
to reduce redundant allocation operation to increase preformance.

e050959103 hwcontext_vaapi: Use PRIME_2 memory type for modifiers.
This way we can pass explicit modifiers in. Sometimes the
modifier matters for the number of memory planes that
libva accepts, in particular when dealing with
driver-compressed textures. Furthermore the driver might
not actually be able to determine the implicit modifier
if all the buffer-passing has used explicit modifier.
All these issues should be resolved by passing in the
modifier, and for that we switch to using the PRIME_2
memory type.

Tested with experimental radeonsi patches for modifiers
and kmsgrab. Also tested with radeonsi without the
patches to double-check it works without PRIME_2 support.

v2:
  Cache PRIME_2 support to avoid doing two calls every time on
  libva drivers that do not support it.

v3:
  Remove prime2_vas usage.

6c57e0b4a8 avutil/frame: Treat frame as uninitialized in get_frame_defaults()
Currently, it also tests whether extended_data points to something
different than the AVFrame's data array and frees extended_data
if it is different. Yet this is only necessary for one of its three
callers, namely av_frame_unref(); meanwhile the other two callers
took measures to avoid this (or rather, to make it to an av_free(NULL)).

This commit moves this chunk to av_frame_unref() (so that
get_frame_defaults() now treats its input as uninitialized)
and removes the now superfluous code in the other two callers.

lavfi/vulkan: split off lavfi-specific code into vulkan_filter.c
The issue is that libavfilter depends on libavcodec, and when doing a
static build, if libavcodec also includes "libavfilter/vulkan.c", then
during link-time, compiling programs will fail as there would be multiple
definitions of the same symbols in both libavfilter and libavcodec's
object files.
Linkers are, however, more permitting if both files that include
a common file that's used as a template are one-to-one identical.
Hence, to make both files the same in the future, export all avfilter
specific functions to a separate file.
There is some work in progress to make templated files like this be
compiled only once, so this is not a long-term solution.

This also removes a macro that could be used to toggle SPIRV compilation
capability on #include-time, as this could cause the files to be different.

of the __ARM_FEATURE_BTI_DEFAULT feature macro.

A binary compiled with BTI support can be executed on an Armv8-A
processor without BTI support because the instructions are defined in
NOP space.

c3502f4f75 libavutil/common: clip nan value to amin
Changes av_clipf to return amin if a is nan.
Before if a is nan av_clipf_c returned nan and
av_clipf_sse would return amax. Now the both
should behave the same.

This works because nan > amin is false.
The max(nan, amin) will be amin.

ff80090374 avutil/utils: Remove racy check from avutil_version()
avutil_version() currently performs several checks before
just returning the version. There is a static int that aims
to ensure that these tests are run only once. The reason is that
there used to be a slightly expensive check, but it has been removed
in 92e3a6fdac. Today running only
once is unnecessary and can be counterproductive: GCC 10 optimizes
all the actual checks away, but the checks_done variable and the code
setting it has been kept. Given that this check is inherently racy
(it uses non-atomic variables), it is best to just remove it.

Makes selection of dxva2/DX9 device type by default as before with explicit d3d11va/DX11 usage to cover more HW configurations.
Added warning message to expect changing default device type in the future.

Fixes TGL / AV1 decode as requires DX11 with explicit DX11 type
selection.

Any other fixes are welcome including OpenCL interop patch since I don't have proper setup to validate this use case

Decoding, encoding, transcoding have been validated.

child_device_type option is responsible for d3d11va/dxva2 device selection

Usage examples:

DirectX 11:
    -init_hw_device qsv:hw,child_device_type=d3d11va
    -init_hw_device qsv:hw,child_device_type=d3d11va,child_device=0
OR
    -init_hw_device d3d11va=dx -init_hw_device qsv@dx

DirectX 9 is still supported but requires explicit selection:

imgutils: expose av_image_copy_plane_uc_from()
The reason why the generic av_image_copy_uc_from() doesn't really
fit in the case for Vulkan is because some planes may be copied via
other methods (such as mapping GPU memory), and if they don't satisfy
the strict alignment requirements, a gpu image->gpu buffer->cpu ram
copy is performed.

We need this for hwcontext_vulkan, and I think this will also be
useful to API users like libplacebo who would rather not write
a custom SIMD memcpy.

math functions and it (directly and indirectly) includes lots of other
headers.

This commit moves the "other fundamental macros" to macros.h which is
a more fitting place.

a1cd62883f avutil/mips: Use $at as MMI macro temporary register
Some function had exceed 30 inline assembly register oprands limiation
when using LOONGSON2 version of MMI macros. We can avoid that by take
$at, which is register reserved for assembler, as temporary register.

As none of instructions used in these macros is pseudo, it is safe to
utilize $at here.

These have mostly been added because of FF_API_*; yet when these were

2c05ee092b avutil/internal, swresample/audioconvert: Remove cpu.h inclusions
These inclusions are not necessary, as cpu.h is already included
wherever it is needed (via direct inclusion or via the arch-specific
headers).
Also remove other unnecessary cpu.h inclusions from ordinary
non-headers.

x86/tx_float: correctly load the transform length
The field is a standard field, yet we were loading it as if it was
a quadword. This worked for forward transforms by chance, but broke
when the transform was inverse.
checkasm couldn't catch that because we only test forward transforms,
which are identical to inverse transforms but with a different revtab.
