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.
For Linux, instructs CMake to use the FFmpeg submodule in externals.
This is HEAVILY based on our usage of the late Unicorn. Minimal change
to MSVC as it uses the yuzu-emu/ext-windows-bin. MinGW now targets the
same ext-windows-bin libraries as MSVC for FFmpeg. Adds FFMPEG_LIBRARIES
to WIN32 and simplifies video_core/CMakeLists.txt a bit.
Given these are only used as function existence checks, we can simplify
some usages of declval, given they aren't particularly useful here.
Reduces a few template instantiations, which at most reduces compile
times a tiny bit.
An identifier containing a starting underscore followed by a capital
letter is reserved by the standard. It's trivial to avoid this by moving
the underscore to the end of the identifier.
While the likelihood of clashing here being minimal, we can turn a
"should not break" scenario into a definitive "will not break" one, so
why not?.
This commit aims to address an exception that occurs when trying to join the Analog object's update_thread.
By using an atomic bool for the status of the update thread, we ensure its value is consistent across the threads accessing it.
