Initial checkin of OCIO filter.

Initial checkin of OCIO filter.

Signed-off-by: Sam.Richards@taurich.org <Sam.Richards@taurich.org>

Change for the right C++ library, should work on linux too.

Adding inverse when using display/view.

Removed comments.

Removed code that was setting the CICP values. Hopefully this can be done through OCIO at some point.

Config cleanup - need a modified require_cpp to handle namespacing.

Switch to using require_cpp so that namespace can be used.

Adding documentation.

Sadly a bit of linting went in here, but more importantly added a threads option to split the image into horizontal tiles, since OCIO was running rather slow.

451ff239e6 avfilter: d3d12 motion estimation filter support 
This commit introduces a video filter `mestimate_d3d12` that provides hardware-accelerated motion estimation using DirectX 12 Video Encoding APIs. The filter leverages GPU hardware motion estimation capabilities to achieve significant performance improvements over the existing software-based mestimate filter.

Sample Command Line:

1. Basic mestimate_d3d12 functionality
```
	ffmpeg_g.exe -hwaccel d3d12va -i test.mp4 -vf mestimate_d3d12=mb_size=16 -f null -
```
2. Motion vector visualization
```
	ffmpeg -hwaccel d3d12va -i input.mp4 -vf "mestimate_d3d12,hwdownload,format=nv12,codecview=mv=pf" -c:v libx264 output.mp4
```

6972b127de avfilter: Add vsrc_amf - AMF based screen capture 
This patch adds screen capture support via AMF vsrc_amf:
ffmpeg -y \
    -filter_complex "vsrc_amf=framerate=120:capture_mode=keep_framerate" \
    -c:v hevc_amf \
    -frames:v 300 \
    output_grab.mp4

If the HW frames pool is insufficient,
increase extra_hw_frames in filter_complex.

    ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 \
           -i input.mp4 -vf scale_d3d12=1920:1280 \

75b8567591 avfilter/scale_cuda: Add support for 4:2:2 chroma subsampling 
The supported YUV pixel formats were separated between planar
and semiplanar. This approach reduces the number of CUDA kernels
for all pixel formats.

This patch:
1. Adds support for YUV 4:2:2 planar and semi-planar formats:
        yuv422p, yuv422p10, nv16, p210, p216
2. Implements new conversion structures and kernel definitions
        for planar and semi-planar formats

016d767c8e lavfi: add drawvg video filter. 
The drawvg filter can draw vector graphics on top of a video, using libcairo. It
is enabled if FFmpeg is configured with `--enable-cairo`.

The language for drawvg scripts is documented in `doc/drawvg-reference.texi`.

There are two new tests:

- `fate-filter-drawvg-interpreter` launch a script with most commands, and
  verify which libcairo functions are executed.
- `fate-filter-drawvg-video` render a very simple image, just to verify that
  libcairo is working as expected.

96821211c2 avfilter: add scale_d3d11 filter 
This commit introduces a new hardware-accelerated video filter, scale_d3d11,
which performs scaling and format conversion using Direct3D 11. The filter enables
efficient GPU-based scaling and pixel format conversion (p010 to nv12), reducing
CPU overhead and latency in video pipelines.

545f721b44 avfilter/vf_colordetect: add new color range detection filter 
This filter can detect various properties about the image, including
whether or not there are out-of-range values, or whether the input appears
to use straight or premultiplied alpha.

Of course, these can only be heuristics, with "undetermined" as the base
case. While we can definitely prove the existence of full range or
straight alpha colors, we can never infer the opposite.

The filter shares the same options as the software pad filter.

vpp_amf supports simple scaling algorithms & color conversion.
sr_amf supports advanced scaling algorithms such as FSR & can
be used for upscaling only.
