The ffmpeg submodule held prebuilt libraries for every platform next to the
sources (about 1.5 GB checked out), and nothing uses those any more. Only the
needed sources are copied in, from the submodule's commit, along with every
header and template they include. The path is new, so checking out commits on
either side of this works.
It's also cut down to what PPSSPP uses: the H.264, AAC, MP3, ATRAC3 and ATRAC3+
decoders, the H.264 parser, the demuxers as before, and the FFV1 encoder, AVI
muxer and file protocol for AVI dumping. config.h takes its CONFIG_ values from
FFmpeg 3.0.2's own configure run with just those enabled. The raw H.264 demuxer
stays even though nothing opens raw H.264: probing PSMF data uses it to identify
the video stream's codec, which otherwise comes out as none.
On top of that:
- The files nothing links (configure would build them, but they're never pulled
out of the static library, going by the GCC link map) are left out: mostly
libavutil's crypto and hashing and the alternative DCT/IDCT/FFT versions.
- libswresample isn't built, now that nothing uses it.
- The H.264 decoder only does 8-bit video, which is all the PSP has. The SPS
parser rejects any other bit depth, and the DSP files no longer build their 9-
to 16-bit variants, which the linker kept because the init functions pick one
by bit depth at run time.
That's 160 files to compile instead of 277, and 391 of FFmpeg's vendored, about
5.8 MB. The README in ext/ffmpeg has what was done, the PPSSPP patches in the
copy, how to add a component, and the tradeoffs.

ext/ffmpeg-build/ffmpeg.vcxproj (and UWP/ffmpeg_UWP for UWP) builds the same
sources as CMake, copied from sources.mk by update_vcxproj.py. It's optimized in
Debug too, and without /Zc:inline, since MSVC otherwise keeps references to
disabled components that FFmpeg expects the compiler to drop.
The projects that linked the prebuilt libraries reference it instead, and take
the headers from the source tree.

It has done nothing since 2017. iCade input came through iCadeReaderView,
a hidden UIKeyInput view that decoded the controller's keystrokes, and
f0ba66fcd6 ("add support for smart keyboard") commented out the code
that created it. Nothing has made one since, so the view controller's
iCadeEventDelegate methods and the ICadeTracker behind them were never
called.
iCade controllers present themselves to iOS as Bluetooth keyboards, so
their keys still arrive as hardware keyboard presses, which can be
mapped like any other keys. Modern controllers go through
GameController.framework anyway.

Windows now uses the same host interface as SDL and iOS: sceUsbMic sends
startRecording/stopRecording/deviceChanged, and drains buffered input on
the CPU thread with pollRecording. A capture thread asks WASAPI for mono
16-bit at the game's rate (it converts from the mix format, so no more
ffmpeg resampling), and copies packets into a lock-free ring buffer.
It reopens the device when the selection changes, and retries once a
second if the device is missing or gets unplugged.
The device list comes from the active capture endpoints. Their friendly
names are the ones Media Foundation reported, so existing MicDevice
settings still match. An empty setting, now selectable as Auto like on
SDL, means the default capture device.
The Media Foundation audio capture code is removed; the camera still
uses it.

Sideloaded builds read hardware keyboard events from the private
UIEvent._gsEvent, at offsets hardcoded for iOS 7 and 9, through a
UIApplication subclass. The UIPress path the App Store build uses works
from iOS 13.4, so use it in all builds, and delete the hack along with
PPSSPPUIApplication and SmartKeyboardMap.
System_Vibrate asked the private UIDevice feedbackSupportLevel whether
to use the feedback generator, in App Store builds too, and sideloaded
builds fell back to the private AudioServicesPlaySystemSoundWithVibration.
The feedback generator just does nothing on devices without a Taptic
Engine, so always use it. That leaves the iPhone 6s and first SE
without virtual button vibration in sideloaded builds.

Oboe uses AAudio on Android 8.1+ and falls back to OpenSL ES on older
devices. Output and microphone input both go through it. The mic now gets
resampled by Oboe from the device's rate to whatever the game asks for.
New: when a stream is disconnected (headphones unplugged, Bluetooth device
going away), it's reopened on the new default device instead of going
silent.
Oboe 1.11.0 is added as a submodule, built through ext/oboe-build for CMake
and as a module in Android.mk.

The Ant build hasn't been runnable since the SDK dropped tools/ant/, so build.xml,
custom_rules.xml, ab-ant.sh, ant-build.bat, project.properties and
proguard-project.txt all go. Plus some orphans: buildassets.sh (nothing called it),
build.sh (still referred to "phoenix"), symx86.cmd (x86 isn't in APP_ABI) and
README.TXT (Eclipse import instructions).
ab.sh and ab.cmd no longer copy assets into android/assets - only the Ant/Eclipse
packaging ever read that directory. Gradle packages the repo-root assets/ directly
and ndk-build doesn't look at assets at all, so the stray copy only made it unclear
where the APK's assets come from. Noted how that actually works in docs/building.md.

Our Qt backend has long been left behind and doesn't even support Vulkan
currently. There would be a lot of work to make it viable, and I don't
think anyone is really interested.
ImGui on SDL will soon fulfill the need for a more classic user interface
with a menu bar on Linux, and on Mac we already have a native UI.
libretro/libretro_vulkan.cpp got PPSSPP's libretro core working with
RetroArch's Vulkan integration by globally monkey-patching PPSSPP's Vulkan
loader function pointers (vkCreateInstance, vkCreateDevice,
vkCreateSwapchainKHR, vkAcquireNextImageKHR, vkQueuePresentKHR,
vkQueueSubmit, etc.) so the unmodified VulkanContext class would end up
wrapping RetroArch's already-existing VkInstance/VkDevice instead of
creating its own, and so a fake VkSwapchainKHR (a self-managed array of
images synced against RetroArch's retro_hw_render_interface_vulkan
callbacks) could stand in for the real swapchain that libretro's Vulkan
model doesn't have. Flagged in-code as "a wacky wrapper".
Replaces that with first-class support in VulkanContext for the two things
libretro actually needs:
- Adopting an externally-created instance/device instead of faking
vkCreateInstance/vkCreateDevice: VulkanContext::CreateInstanceExternal()
adopts RetroArch's VkInstance; CreateDevice() gained optional
extraDeviceExtensions/extraRequiredFeatures params so RetroArch's
requirements get merged into a real vkCreateDevice() call;
ownsInstance_/ownsDevice_ flags (the latter set via
SetDeviceExternallyOwned()) mean DestroyInstance()/DestroyDevice() skip
the real vkDestroy* calls when something else owns the object, without
needing to intercept anything. VulkanLoader gained
VulkanLoadFromGetInstanceProcAddr() for bootstrapping from a
host-supplied proc-addr getter instead of dlopen/dlsym-ing the loader
ourselves - vkGetDeviceProcAddr is resolved via the real instance handle
(not NULL), since per the Vulkan spec it's not one of the handful of
commands queryable with a NULL instance.
- A pluggable presentation backend (Common/GPU/Vulkan/VulkanPresentation.h)
for hosts with no real VK_KHR_swapchain, replacing the fake-swapchain-
handle trick. VulkanContext::GetPresentation() is null by default, so
every existing platform's real-swapchain code path is untouched;
libretro/LibretroVulkanPresentation implements this interface directly
against retro_hw_render_interface_vulkan, as real class state instead of
file-scope globals. Several pieces of state that are normally only
populated as a side effect of ReinitSurface()/InitSwapchain() - the
graphics queue/queue family index (ChooseQueue() is entangled with
real-surface presentation-support checks), the swapchain format, and
the available present modes - needed presentation-aware fallbacks since
libretro never calls that real-surface path at all.
libretro/LibretroVulkanContext.cpp now drives VulkanContext's real, public
API directly - no more hijacked function pointers, no more fake surface or
swapchain. libretro/libretro_vulkan.cpp is deleted.
Verified with a full build+run in RetroArch (not just compile-time
checks): the libretro Makefile doesn't track header dependencies
(cl.exe doesn't support -MMD/-MP, and Makefile.common never sets up an
equivalent), so a `make clean` full rebuild is required after any header
change to avoid linking stale object code from before the change - several
of the fixes above were initially masked by exactly that.
Since we no longer support pre-Vista Windows, DirectSound support is no
longer needed. WASAPI is always going to be best.
Soon I'll upgrade our WASAPI backend with a new low-latency mode.
* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
