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.

This commit adds a structure to contain parsed EXIF metadata, as well
as code to read and write that struct from/to binary EXIF buffers. Some
internal functions have been moved to exif_internal.h. Code to read
from this new struct and write to an AVDictionary **dict has been added
as well in order to preserve interoperability with existing callers.
The only codec changes so far as of this commit are to call these
interop functions, but in future commits there will be codec changes to
use the new parsing routines instead.

Commit f256487cd8 bumped requirement to
1.1.0 for OPENSSL_init_ssl.
Bump this again to 1.1.1, because it was an LTS version. Although it has
no mainline support anymore, it still has paid/premium support. 1.1.0 has
no support at all.
Motivated for use of BIO_read_ex() for next commits.

opt_codec() is mostly copied over from ffplay.c.
This is useful when different decoders have different capabilities,
or to test a specific decoder.

This changes configure to stop disabling -ftree-vectorize on
GCC versions 13 and newer, on major architectures.
Background:
- Original `-fno-tree-vectorize` was added in 2009 in commit
973859f523 to avoid compiler errors.
- Re-enabled in 2016 in commit cb8646af24 but caused failures due
to inline CABAC assembly issues and was disabled again in
fd6dbc5385.
- Commit 182663a58a in 2023 fixed the inline CABAC assembly issues.
- Recent versions of GCC, in particular 13 and newer, seem to
generally work reliably with respect to vectorization, although bugs
have been observed on Loongarch.
Cautiously allow the GCC default of having vectorization enabled,
on major architectures where we expect to see enough testing. If
further issues are observed, they should be reported and noted here in
configure, so the workarounds can be scoped and version limited.
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.
- Changes in mov_write_video_tag function to handle APV elementary stream
- Provided structure APVDecoderConfigurationRecord that specifies the decoder configuration information for APV video content

This patch adds the pad_cuda video filter. A filter similar to the existing pad filter but accelerated by CUDA.
The filter shares the same options as the software pad filter.
Example usage:
ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i input.mp4 -vf "pad_cuda=w=iw+100:h=ih+100:x=-1:y=-1:color=red" out.mp4

libjxl supports animated encoding, so we add a wrapper to the
library using the receive_packet callback method.
This code was based largely on a patch sent by Zsolt Vadász,
although it was updated to use more recent coding practices
and many of the leaks and issues were fixed.
