Andreas Rheinhardt 3e669b24e2 avutil/hwcontext: Allocate AVHWFramesCtx jointly with its internals
This is possible because the lifetime of these structures coincide.
It has the advantage of allowing to remove AVHWFramesInternal
from the public header; given that AVHWFramesInternal.priv is no more,
most accesses to AVHWFramesInternal are no more; indeed, the only
field accessed of it outside of hwcontext.c is the internal frame pool,
making this commit very simple.

Haihao Xiang 3e61b7dd7f qsv: remove mfx/ prefix from mfx headers
The following Cflags has been added to libmfx.pc, so mfx/ prefix is no
longer needed when including mfx headers in FFmpeg.
   Cflags: -I${includedir} -I${includedir}/mfx

Some old versions of libmfx have the following Cflags in libmfx.pc
   Cflags: -I${includedir}

We may add -I${includedir}/mfx to CFLAGS when running 'configure
--enable-libmfx' for old versions of libmfx, if so, mfx headers without
mfx/ prefix can be included too.

If libmfx comes without pkg-config support, we may do a small change to
the settings of the environment(e.g. set -I/opt/intel/mediasdk/include/mfx
instead of -I/opt/intel/mediasdk/include to CFLAGS), then the build can
find the mfx headers without mfx/ prefix

After applying this change, we won't need to change #include for mfx
headers when mfx headers are installed under a new directory.

This is in preparation for oneVPL support (mfx headers in oneVPL are
installed under vpl directory)

Soft Works 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)

Wenbin Chen 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.

hwcontext: add av_hwdevice_ctx_create_derived_opts
This allows for users who derive devices to set options for the
new device context they derive.
The main use case of this is to allow users to enable extensions
(such as surface drawing extensions) in Vulkan while deriving from
the device their frames are on. That way, users don't need to write
any initialization code themselves, since the Vulkan spec invalidates
mixing instances, physical devices and active devices.
Apart from Vulkan, other hwcontexts ignore the opts argument since they
don't support options at all (or in VAAPI and OpenCL's case, options are
currently only used for device selection, which device_derive overrides).

Mark Thompson 468f003843 hwcontext_qsv: Try to select a matching VAAPI device by default
Tries to find a device backed by the i915 kernel driver and loads the iHD
VAAPI driver to use with it.  This reduces confusion on machines with
multiple DRM devices and removes the surprising requirement to set the
LIBVA_DRIVER_NAME environment variable to use libmfx at all.
