Due to making the decode frames context use the coded size, the
filter started to display those artifacts as it reused the input frame's size.
Change it to instead output the real image size for images, not the input.
The code above this does a whitelist on desc->flags, which now includes
the (disallowed) AV_PIX_FMT_FLAG_XYZ for XYZ formats. So there is no
more need for a separate check, here.
These are not supported by the drawing functions at all, and were
incorrectly advertised as supported in the past.
Note: This check is added only to separate the logic change from the API
change in the following commit, and will be removed again after it
becomes redundant.
The vidstab library added support in Nov 2020 for writing/reading
the transforms data in binary in addition to ASCII. The library default
was changed to binary format but no changes were made to the AVfilters
resulting in data file for writing or reading being always opened as text.
This effectively broke the filters.
Option added to vidstabdetect to specify file format and open files in
both filters with the correct attributes.
This logic only covers the case of yuv420p. Extend this logic to cover
*all* vertically subsampled YUV formats, which require the same
interlaced scaling logic.
Fortunately, we can get away with re-using the same code for both JPEG
and MPEG range YUV, because the only difference here is the horizontal
alignment. (Which I omit touching for now, to avoid introducing possibly
unintended changes in default behavior)
Fixes multiplane support on Nvidia.
Also, remove the ENCODE usage, even if the driver signals it as supported.
Currently, it's not used, and when it is used, it'll be gated behind
two extension checks.
Instead, use forward declarations; and in order not to affect
any user include these headers for them, but not internally.
This has the advantage of removing implicit inclusions of these
headers from almost all files providing codecs.

In this logical branch, fq->queued and fq->allocated must be equal.
Deleting this code will make it easier to understand the logic
(copy the data before tail to the newly requested space)

This function is used by the AARCH64 code to filter a few
remaining lines in case the dimensions are not suitably
aligned; it is furthermore also used by checkasm to actually
test the AARCH64 code against. But it is normally not used
and this patch therefore moves it in bwdifdsp.h as a static
inline function so that it can be avoided if possible
or inlined where necessary.

Otherwise checkasm/vf_bwdif.c pulls in vf_bwdif.c and
then all of libavfilter. Besides being bad size-wise
this also has the downside that it pulls in
avpriv_(cga|vga16)_font from libavutil which are marked
as being imported from another library when building
libavfilter as a DLL and this breaks checkasm because
it links both lavfi and lavu statically.

This already avoids unnecessary indirectly included headers
in the arch-specific vf_bwdif_init.c files; it is also in
preparation for splitting the actual functions out of vf_bwdif.c.

Dnn models has different data preprocess requirements. Scale and mean
parameters are added to preprocess input data.
Signed-off-by: Wenbin Chen <wenbin.chen@intel.com>
Dnn models have different input layout (NCHW or NHWC), so a
"layout" option is added
Use openvino's API to do layout conversion for input data. Use swscale
to do layout conversion for output data as openvino doesn't have
similiar C API for output.

The PSNR filter uses the pixel values without considering
the color ranges. This is incorrect. Patch adds a warning
so at least the user knows it.
Let's see an example:
(1) Let's get a simple black pixel/white pixel image.
```
$ echo -n -e "\x00\x00\x00\xff\xff\xff" > /tmp/foo.rgb24
```
(2) From this image, let's distill full and limited range y4m
copies.
```
$ ffmpeg -y -f rawvideo -video_size 2x1 -pix_fmt rgb24 -i /tmp/foo.rgb24 -vf scale="out_range=full" -pix_fmt yuv420p /tmp/foo.full.y4m
$ xxd /tmp/foo.full.y4m

```
and
```
$ ffmpeg -y -f rawvideo -video_size 2x1 -pix_fmt rgb24 -i /tmp/foo.rgb24 -vf scale="out_range=limited" -pix_fmt yuv420p /tmp/foo.limited.y4m
$ xxd /tmp/foo.limited.y4m
00000000: 5955 5634 4d50 4547 3220 5732 2048 3120 YUV4MPEG2 W2 H1

00000050: 10eb 8080 ....
```
Note that the 2x images are the same (both have 1x pixel at the
darkest black, and one at the brightest white). Only difference
is the range.
(3) Let's calculate the PSNR score:
```
$ ./ffmpeg -filter_threads 1 -filter_complex_threads 1 -i /tmp/foo.full.y4m -i /tmp/foo.limited.y4m -lavfi "psnr" -f null -
...
[Parsed_psnr_0 @ 0x2f5dac0] PSNR y:22.972065 u:inf v:inf average:25.982365 min:25.982365 max:25.982365
```
As we are comparing an image with itself, we expect "y:inf" as the
luma PSNR. Issue here is that the PSNR filter just uses the pixel
values, ignoring the color ranges.
A possible solution would be to have the filter do the conversion.
Proposed solution is to add a warning.
```
$ ./ffmpeg -filter_threads 1 -filter_complex_threads 1 -i /tmp/foo.full.y4m -i /tmp/foo.limited.y4m -lavfi "psnr" -f null -
...
[Parsed_psnr_0 @ 0x2f5dac0] master and reference frames use different color ranges (pc != tv)
...
[Parsed_psnr_0 @ 0x2f5dac0] PSNR y:22.972065 u:inf v:inf average:25.982365 min:25.982365 max:25.982365
```
Tested:
Ran fate.
```
$ make fate -j
...
TEST seek-lavf-ppmpipe
TEST seek-lavf-pgmpipe
TEST seek-lavf-mxf_opatom
```
When ov_model_const_input_by_name/ov_model_const_output_by_name
failed, input_port/output_port can be wild pointer.
