As described in
https://github.com/yuzu-emu/yuzu/pull/9395#discussion_r1047456172
checking for PKG_CONFIG_FOUND before calling pkg_search_module() is
unneeded, and some find modules (like FindFFmpeg.cmake) don't do this
already. Consequently, this patch removes these checks.
Uses find_package_handle_standard_args to handle the find_package call
from the root CMakeLists. Removes all the unnecessary logic after the
find_package and just sets it to REQUIRED.
With this patch I've deleted a few find modules that are now unused
since the vcpkg transition, as the CMake code now forces CONFIG mode for
Catch2, fmt and nlohmann_json.
I've then simplified the lz4, opus, and zstd modules by exclusively
using pkg-config. They were using it already, but were ignoring the
result. Also, I believe that manually looking for libraries was required
for Conan to work, and it is thus not needed anymore.
Lastly, I believe that there is no platform that ships these system libs
without pkg-config/pkgconf, so requiring it should be fine.
[REUSE] is a specification that aims at making file copyright
information consistent, so that it can be both human and machine
readable. It basically requires that all files have a header containing
copyright and licensing information. When this isn't possible, like
when dealing with binary assets, generated files or embedded third-party
dependencies, it is permitted to insert copyright information in the
`.reuse/dep5` file.
Oh, and it also requires that all the licenses used in the project are
present in the `LICENSES` folder, that's why the diff is so huge.
This can be done automatically with `reuse download --all`.
The `reuse` tool also contains a handy subcommand that analyzes the
project and tells whether or not the project is (still) compliant,
`reuse lint`.
Following REUSE has a few advantages over the current approach:
- Copyright information is easy to access for users / downstream
- Files like `dist/license.md` do not need to exist anymore, as
`.reuse/dep5` is used instead
- `reuse lint` makes it easy to ensure that copyright information of
files like binary assets / images is always accurate and up to date
To add copyright information of files that didn't have it I looked up
who committed what and when, for each file. As yuzu contributors do not
have to sign a CLA or similar I couldn't assume that copyright ownership
was of the "yuzu Emulator Project", so I used the name and/or email of
the commit author instead.

We had used conan for opus before, but there was a bug in the AVX detection.
However we still had the Findopus.cmake file within the repository, but not used.
This patch reenables the Findopus helper and prefer the system wide installation of opus.
Sets YUZU_USE_BUNDLED_FFMPEG as a CMake dependent option that is OFF on
Linux and ON for WIN32 targets. If FFmpeg is not found when
YUZU_USE_BUNDLED_FFMPEG is OFF, the bundled module/binaries are used
instead.
Reverts earlier changes to FindFFmpeg a bit, mostly to keep parity with
it's Citra version a bit. Now _FFmpeg_ALL_COMPONENTS lists all
components. We overwrite FFmpeg_LIBRARIES and FFmpeg_INCLUDE_DIR after
using the module.
Also renames related CMake variables to match both the Find*FFmpeg* and
variables defined within the file. Fixes odd errors produced by the old
FindFFmpeg.
Citra's FindFFmpeg is slightly modified here: adds Citra's copyright at
the beginning, renames FFmpeg_INCLUDES to FFmpeg_INCLUDE_DIR, disables a
few components in _FFmpeg_ALL_COMPONENTS, and adds the missing avutil
component to the comment above.
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.
