Since 580e168a94, av_size_mult() is no
longer inlined; on systems where interposing is a thing, this also
inhibits the compiler from inlining said function into the internal
callers of said function, although inlining such a small function is
typically beneficial: With GCC 10.3 on Ubuntu x64 and -O3 this decreases
the size of av_realloc_array from 91B to 23B, from 129B to 81B for
av_realloc_f and from 77B to 23B for each of av_malloc_array,
av_mallocz_array and av_calloc.

This allows user set hw_device_ctx instead of hw_frames_ctx for QSV
decoders, hence we may remove the ad-hoc libmfx setup code from FFmpeg.
"-hwaccel_output_format format" is applied to QSV decoders after
removing the ad-hoc libmfx code. In order to keep compatibility with old
commandlines, the default format is set to AV_PIX_FMT_QSV, but this
behavior will be removed in the future. Please set "-hwaccel_output_format qsv"
explicitly if AV_PIX_FMT_QSV is expected.
The normal device stuff works for QSV decoders now, user may use
"-init_hw_device args" to initialise device and "-hwaccel_device
devicename" to select a device for QSV decoders.
"-qsv_device device" which was added for workarounding device selection
in the ad-hoc libmfx code still works
For example:
$> ffmpeg -init_hw_device qsv=qsv:hw_any,child_device=/dev/dri/card0
-hwaccel qsv -c:v h264_qsv -i input.h264 -f null -
/dev/dri/renderD128 is actually open for h264_qsv decoder in the above
command without this patch. After applying this patch, /dev/dri/card0
is used.
$> ffmpeg -init_hw_device vaapi=va:/dev/dri/card0 -init_hw_device
qsv=hw@va -hwaccel_device hw -hwaccel qsv -c:v h264_qsv -i input.h264
-f null -
device hw of type qsv is not usable in the above command without this
patch. After applying this patch, this command works as expected.

If a slice header fails to parse, and the next one uses different Sequence and
Picture parameter sets, certain values may not be read if they are not coded,

The existing error concealment makes no sense for the image formats, they
use transformed source images which is different from keyframe + MC+difference
for which the error concealment is designed.
Of course feel free to re-enable this if you have a case where it works and
improves vissual results

This commit adds the case handling if the asynchronous execution
of a request fails by checking the exit status of the thread when
joining before starting another execution. On failure, it does the
cleanup as well.

Since requests are running in parallel, there is inconsistency in
the status of the execution. To resolve it, we avoid using mutex
as it would result in single TF_Session running at a time. So add
TF_Status to the TFRequestItem

This commit enables async execution in the TensorFlow backend
and adds function to flush extra frames.
The async execution mechanism executes the TFInferRequests on
a separate thread which is joined before the next execution of
same TFRequestItem/while freeing the model.
The following is the comparison of this mechanism with the existing
sync mechanism on TensorFlow C API 2.5 CPU variant.
Async Mode: 4m32.846s
Sync Mode: 5m17.582s
The above was performed on super resolution filter using SRCNN model.

After standardizing the use of 'pxor' in commit 'ebedd26', FFmpeg
build failed with upstream compiler, for 'pxor' is not supported
in time. This patch helps to workaround the build failure by
checking whether 'pxor' is supported during configuration, if not,
MMI will be disabled.

If autoflushing on a new packet (e.g. due to the frag_every_frame
flag being set), there's no samples to be written in the new fragment,
so we can't overwrite the track duration in order to make it line
up with the next packet to be written.

hybrid2_re() has a parameter declared as "const INTFLOAT filter[8]",

the code itself only uses seven elements, so change the parameter.

The function definition used float *data_buf[14], although there are
only 13 elements (and only 13 are used); the declaration used 13.
Given that the type will be converted to float **data_buf anyway,
this is not in violation of the C specs, but nevertheless a bug.
GCC 11 has a new warning for this -Warray-parameter.
