FFmpeg_DLL_DIR does not exist anywhere else in the repository.
Evidently, the variable name was antiquated at some point, but it
continued to work here as a zombie.
Update the name and avoid copy issues.
This PR rearranges things in the CMake system to make compiling with Qt6 possible
1. Camera API has changed in Qt6, so the camera feature is disabled
2. A previous fix involving QLocale is now version gated.
3. QRegExp replaced with QRegularExpression, see #5343
4. Qt6_LOCATION option added to specify a location to search for Qt6
(see examples below)
5. windeployqt is used to copy Qt6 files into the build directory on Windows
Notes for Arch Linux
Arch install happened to have qt6-base qt6-declarative qt6-translations installed
mkdir build && cd build
cmake .. -GNinja -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF -DENABLE_QT6=YES -DYUZU_USE_BUNDLED_QT=NO

Qt wants users to download precompiled libraries via an online installer,
it is worth noting that the GPL/LGPL takes precendence over any ...
In the Qt Maintenance tool, under a version, such as 6.3.1
Select "MSVC 2019 64-bit"
Under Additional Libraries Qt Multimedia may be of use for Camera support
For the Web Applet I had to select the following:

[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.

If the build is from a non-repository, these functions will return empty. This
patch allows using defines to CMake to set version info such as
-DGIT_BRANCH=master.
If the local version of Qt is older than the minimum version required by
yuzu, download a pre-built binary package from yuzu-emu/ext-linux-bin
and build yuzu with it, instead.
This also requires linking yuzu to the correct libraries after building
it, and copying over the required binaries when building yuzu.
This sets the Qt requirement to 5.12, which is intentionally behind the
versions used by our toolchains since they are not all updated yet to
5.15.
Building SDL2 from externals is incompatible with Conan's version of
libiconv, a requirement of Conan's Boost package. Solution is to use the
same Boost package in use by the linux-fresh container. This tells CMake
to download boost_1_75_0.tar.xz from yuzu-emu/ext-linux-bin at CMake's
configuration step, much the same way Qt and FFmpeg are downloaded for
Windows.
Also makes DownloadExternals.cmake cross-platform. Although the CMake
code is not entirely specific to Linux, only Linux has Boost libraries
available at ext-linux-bin, whereas there is no equivalent Boost package
for Windows at ext-windows-bin. caveat emptor
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.
This also allows us to remove our dependency on Python.
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.
