If you ever want to use JNI in a native thread (created by "SDL_CreateThread()"),

the work-around is to find class/method, in you "main()" thread, and to use them

Instructions:
1. Open SDL.xcodeproj (located in Xcode-iOS/SDL) in Xcode.
2. Select your desired target, and hit build.
There are three build targets:
- libSDL.a:
Build SDL as a statically linked library
- testsdl:
Build a test program (there are known test failures which are fine)
- Template:
Package a project template together with the SDL for iPhone static libraries and copies of the SDL headers. The template includes proper references to the SDL library and headers, skeleton code for a basic SDL program, and placeholder graphics for the application icon and startup screen.
1. Open SDL.xcodeproj (located in Xcode/SDL) in Xcode.
2. Select your desired target, and hit build.
==============================================================================
Build SDL for iOS from the command line
==============================================================================
1. cd (PATH WHERE THE SDL CODE IS)/build-scripts
2. ./iosbuild.sh
If everything goes fine, you should see a build/ios directory, inside there's
two directories "lib" and "include".
"include" contains a copy of the SDL headers that you'll need for your project,
make sure to configure XCode to look for headers there.
"lib" contains find two files, libSDL2.a and libSDL2main.a, you have to add both
to your XCode project. These libraries contain three architectures in them,
armv6 for legacy devices, armv7, and i386 (for the simulator).
By default, iosbuild.sh will autodetect the SDK version you have installed using
xcodebuild -showsdks, and build for iOS >= 3.0, you can override this behaviour
by setting the MIN_OS_VERSION variable, ie:
MIN_OS_VERSION=4.2 ./iosbuild.sh

Using the Simple DirectMedia Layer for iOS
==============================================================================
FIXME: This needs to be updated for the latest methods
1. Run Xcode and create a new project using the iOS Game template, selecting the Objective C language and Metal game technology.
2. In the main view, delete all files except for Assets and LaunchScreen
3. Right click the project in the main view, select "Add Files...", and add the SDL project, Xcode/SDL/SDL.xcodeproj
4. Select the project in the main view, go to the "Info" tab and under "Custom iOS Target Properties" remove the line "Main storyboard file base name"
5. Select the project in the main view, go to the "Build Settings" tab, select "All", and edit "Header Search Path" and drag over the SDL "Public Headers" folder from the left
6. Select the project in the main view, go to the "Build Phases" tab, select "Link Binary With Libraries", and add SDL2.framework from "Framework-iOS"
7. Select the project in the main view, go to the "General" tab, scroll down to "Frameworks, Libraries, and Embedded Content", and select "Embed & Sign" for the SDL library.
8. In the main view, expand SDL -> Library Source -> main -> uikit and drag SDL_uikit_main.c into your game files
9. Add the source files that you would normally have for an SDL program, making sure to have #include "SDL.h" at the top of the file containing your main() function.
10. Add any assets that your application needs.
11. Enjoy!
Here is the easiest method:
1. Build the SDL library (libSDL2.a) and the iPhone SDL Application template.
2. Install the iPhone SDL Application template by copying it to one of Xcode's template directories. I recommend creating a directory called "SDL" in "/Developer/Platforms/iOS.platform/Developer/Library/Xcode/Project Templates/" and placing it there.
3. Start a new project using the template. The project should be immediately ready for use with SDL.
Here is a more manual method:
1. Create a new iOS view based application.
2. Build the SDL static library (libSDL2.a) for iOS and include them in your project. Xcode will ignore the library that is not currently of the correct architecture, hence your app will work both on iOS and in the iOS Simulator.
3. Include the SDL header files in your project.
4. Remove the ApplicationDelegate.h and ApplicationDelegate.m files -- SDL for iOS provides its own UIApplicationDelegate. Remove MainWindow.xib -- SDL for iOS produces its user interface programmatically.
5. Delete the contents of main.m and program your app as a regular SDL program instead. You may replace main.m with your own main.c, but you must tell Xcode not to use the project prefix file, as it includes Objective-C code.

Hence, in order to convert between the two, some clamping and scaling is necessary on the part of the iPhone SDL joystick driver.

# Mac OS X (aka macOS).
These instructions are for people using Apple's Mac OS X (pronounced
"ten"), which in newer versions is just referred to as "macOS".
From the developer's point of view, macOS is a sort of hybrid Mac and
Unix system, and you have the option of using either traditional
command line tools or Apple's IDE Xcode.
# Command Line Build
To build SDL using the command line, use the standard configure and make
process:
```bash
mkdir build
cd build
../configure
make
sudo make install
```
CMake is also known to work, although it continues to be a work in progress:
```bash
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
sudo make install
```
You can also build SDL as a Universal library (a single binary for both
64-bit Intel and ARM architectures), by using the build-scripts/clang-fat.sh
script.
```bash
mkdir build
cd build
CC=$PWD/../build-scripts/clang-fat.sh ../configure
make
sudo make install
```
This script builds SDL with 10.6 ABI compatibility on 64-bit Intel and 11.0
ABI compatibility on ARM64 architectures. For best compatibility you
should compile your application the same way.
Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
(even if you target back to 10.6 systems). PowerPC support for Mac OS X has
been officially dropped as of SDL 2.0.2. 32-bit Intel, using an older Xcode
release, is still supported at the time of this writing, but current Xcode
releases no longer support it, and eventually neither will SDL.
To use the library once it's built, you essential have two possibilities:
use the traditional autoconf/automake/make method, or use Xcode.
# Caveats for using SDL with Mac OS X
If you register your own NSApplicationDelegate (using [NSApp setDelegate:]),
SDL will not register its own. This means that SDL will not terminate using
SDL_Quit if it receives a termination request, it will terminate like a
normal app, and it will not send a SDL_DROPFILE when you request to open a
file with the app. To solve these issues, put the following code in your
NSApplicationDelegate implementation:
```objc
- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
{
if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_QUIT;
SDL_PushEvent(&event);
}
return NSTerminateCancel;
}
- (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
{
if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_DROPFILE;
event.drop.file = SDL_strdup([filename UTF8String]);
return (SDL_PushEvent(&event) > 0);
}
return NO;
}
```
# Using the Simple DirectMedia Layer with a traditional Makefile
An existing autoconf/automake build system for your SDL app has good chances
to work almost unchanged on macOS. However, to produce a "real" Mac binary
that you can distribute to users, you need to put the generated binary into a
so called "bundle", which is basically a fancy folder with a name like
"MyCoolGame.app".
To get this build automatically, add something like the following rule to
your Makefile.am:
```make
bundle_contents = APP_NAME.app/Contents
APP_NAME_bundle: EXE_NAME
mkdir -p $(bundle_contents)/MacOS
mkdir -p $(bundle_contents)/Resources
echo "APPL????" > $(bundle_contents)/PkgInfo
$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
```
You should replace `EXE_NAME` with the name of the executable. `APP_NAME` is
what will be visible to the user in the Finder. Usually it will be the same
as `EXE_NAME` but capitalized. E.g. if `EXE_NAME` is "testgame" then `APP_NAME`
usually is "TestGame". You might also want to use `@PACKAGE@` to use the
package name as specified in your configure.ac file.
If your project builds more than one application, you will have to do a bit
more. For each of your target applications, you need a separate rule.
If you want the created bundles to be installed, you may want to add this
rule to your Makefile.am:
```make
install-exec-hook: APP_NAME_bundle
rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
mkdir -p $(DESTDIR)$(prefix)/Applications/
cp -r $< /$(DESTDIR)$(prefix)Applications/
```
This rule takes the Bundle created by the rule from step 3 and installs them
into "$(DESTDIR)$(prefix)/Applications/".
Again, if you want to install multiple applications, you will have to augment
the make rule accordingly.
But beware! That is only part of the story! With the above, you end up with
a barebones .app bundle, which is double-clickable from the Finder. But
there are some more things you should do before shipping your product...
1. The bundle right now probably is dynamically linked against SDL. That
means that when you copy it to another computer, *it will not run*,
unless you also install SDL on that other computer. A good solution
for this dilemma is to static link against SDL. On OS X, you can
achieve that by linking against the libraries listed by
```bash
sdl-config --static-libs
```
instead of those listed by
```bash
sdl-config --libs
```
Depending on how exactly SDL is integrated into your build systems, the
way to achieve that varies, so I won't describe it here in detail
2. Add an 'Info.plist' to your application. That is a special XML file which
contains some meta-information about your application (like some copyright
information, the version of your app, the name of an optional icon file,
and other things). Part of that information is displayed by the Finder
when you click on the .app, or if you look at the "Get Info" window.
More information about Info.plist files can be found on Apple's homepage.
As a final remark, let me add that I use some of the techniques (and some
variations of them) in [Exult](https://github.com/exult/exult) and
[ScummVM](https://github.com/scummvm/scummvm); both are available in source on
the net, so feel free to take a peek at them for inspiration!
# Using the Simple DirectMedia Layer with Xcode
These instructions are for using Apple's Xcode IDE to build SDL applications.
## First steps
The first thing to do is to unpack the Xcode.tar.gz archive in the
top level SDL directory (where the Xcode.tar.gz archive resides).
Because Stuffit Expander will unpack the archive into a subdirectory,
you should unpack the archive manually from the command line:
```bash
cd [path_to_SDL_source]
tar zxf Xcode.tar.gz
```
This will create a new folder called Xcode, which you can browse
normally from the Finder.
## Building the Framework
The SDL Library is packaged as a framework bundle, an organized
relocatable folder hierarchy of executable code, interface headers,
and additional resources. For practical purposes, you can think of a
framework as a more user and system-friendly shared library, whose library
file behaves more or less like a standard UNIX shared library.
To build the framework, simply open the framework project and build it.
By default, the framework bundle "SDL.framework" is installed in
/Library/Frameworks. Therefore, the testers and project stationary expect
it to be located there. However, it will function the same in any of the
following locations:
* ~/Library/Frameworks
* /Local/Library/Frameworks
* /System/Library/Frameworks
## Build Options
There are two "Build Styles" (See the "Targets" tab) for SDL.
"Deployment" should be used if you aren't tweaking the SDL library.
"Development" should be used to debug SDL apps or the library itself.
## Building the Testers
Open the SDLTest project and build away!
## Using the Project Stationary
Copy the stationary to the indicated folders to access it from
the "New Project" and "Add target" menus. What could be easier?
## Setting up a new project by hand
Some of you won't want to use the Stationary so I'll give some tips:
(this is accurate as of Xcode 12.5.)
* Click "File" -> "New" -> "Project...
* Choose "macOS" and then "App" from the "Application" section.
* Fill out the options in the next window. User interface is "XIB" and
Language is "Objective-C".
* Remove "main.m" from your project
* Remove "MainMenu.xib" from your project
* Remove "AppDelegates.*" from your project
* Add "\$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
* Add "\$(HOME)/Library/Frameworks" to the frameworks search path
* Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
* Add your files
* Clean and build
## Building from command line
Use `xcode-build` in the same directory as your .pbxproj file
## Running your app
You can send command line args to your app by either invoking it from
the command line (in *.app/Contents/MacOS) or by entering them in the
Executables" panel of the target settings.
# Implementation Notes
Some things that may be of interest about how it all works...
## Working directory
In SDL 1.2, the working directory of your SDL app is by default set to its
parent, but this is no longer the case in SDL 2.0. SDL2 does change the
working directory, which means it'll be whatever the command line prompt
that launched the program was using, or if launched by double-clicking in
the finger, it will be "/", the _root of the filesystem_. Plan accordingly!
You can use SDL_GetBasePath() to find where the program is running from and
chdir() there directly.
## You have a Cocoa App!
Your SDL app is essentially a Cocoa application. When your app
starts up and the libraries finish loading, a Cocoa procedure is called,
which sets up the working directory and calls your main() method.
You are free to modify your Cocoa app with generally no consequence
to SDL. You cannot, however, easily change the SDL window itself.
Functionality may be added in the future to help this.

Mac OS X
==============================================================================
These instructions are for people using Apple's Mac OS X (pronounced
"ten").
From the developer's point of view, OS X is a sort of hybrid Mac and
Unix system, and you have the option of using either traditional
command line tools or Apple's IDE Xcode.
Command Line Build
==================
To build SDL using the command line, use the standard configure and make
process:
./configure
make
sudo make install
You can also build SDL as a Universal library (a single binary for both
32-bit and 64-bit Intel architectures), on Mac OS X 10.7 and newer, by using
the gcc-fat.sh script in build-scripts:
mkdir mybuild
cd mybuild
CC=$PWD/../build-scripts/gcc-fat.sh CXX=$PWD/../build-scripts/g++-fat.sh ../configure
make
sudo make install
This script builds SDL with 10.5 ABI compatibility on i386 and 10.6
ABI compatibility on x86_64 architectures. For best compatibility you
should compile your application the same way.
Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK
(even if you target back to 10.5 systems). PowerPC support for Mac OS X has
been officially dropped as of SDL 2.0.2.
To use the library once it's built, you essential have two possibilities:
use the traditional autoconf/automake/make method, or use Xcode.
==============================================================================
Caveats for using SDL with Mac OS X
==============================================================================
Some things you have to be aware of when using SDL on Mac OS X:
- If you register your own NSApplicationDelegate (using [NSApp setDelegate:]),
SDL will not register its own. This means that SDL will not terminate using
SDL_Quit if it receives a termination request, it will terminate like a
normal app, and it will not send a SDL_DROPFILE when you request to open a
file with the app. To solve these issues, put the following code in your
NSApplicationDelegate implementation:
- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender
{
if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_QUIT;
SDL_PushEvent(&event);
}
return NSTerminateCancel;
}
- (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename
{
if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) {
SDL_Event event;
event.type = SDL_DROPFILE;
event.drop.file = SDL_strdup([filename UTF8String]);
return (SDL_PushEvent(&event) > 0);
}
return NO;
}
==============================================================================
Using the Simple DirectMedia Layer with a traditional Makefile
==============================================================================
An existing autoconf/automake build system for your SDL app has good chances
to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
that you can distribute to users, you need to put the generated binary into a
so called "bundle", which basically is a fancy folder with a name like
"MyCoolGame.app".
To get this build automatically, add something like the following rule to
your Makefile.am:
bundle_contents = APP_NAME.app/Contents
APP_NAME_bundle: EXE_NAME
mkdir -p $(bundle_contents)/MacOS
mkdir -p $(bundle_contents)/Resources
echo "APPL????" > $(bundle_contents)/PkgInfo
$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
You should replace EXE_NAME with the name of the executable. APP_NAME is what
will be visible to the user in the Finder. Usually it will be the same
as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME
usually is "TestGame". You might also want to use `@PACKAGE@` to use the package
name as specified in your configure.ac file.
If your project builds more than one application, you will have to do a bit
more. For each of your target applications, you need a separate rule.
If you want the created bundles to be installed, you may want to add this
rule to your Makefile.am:
install-exec-hook: APP_NAME_bundle
rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
mkdir -p $(DESTDIR)$(prefix)/Applications/
cp -r $< /$(DESTDIR)$(prefix)Applications/
This rule takes the Bundle created by the rule from step 3 and installs them
into "$(DESTDIR)$(prefix)/Applications/".
Again, if you want to install multiple applications, you will have to augment
the make rule accordingly.
But beware! That is only part of the story! With the above, you end up with
a bare bone .app bundle, which is double clickable from the Finder. But
there are some more things you should do before shipping your product...

Joysticks in SDL2:
------------------
The joystick code in SDL2 is a direct forward-port from the SDL-1.2 version.
Here is the original documentation from SDL-1.2:
The Joystick detection only works for standard joysticks (2 buttons, 2 axes
and the like). Therefore, if you use a non-standard joystick, you should
specify its features in the SDL_OS2_JOYSTICK environment variable in a batch
file or CONFIG.SYS, so SDL applications can provide full capability to your
device. The syntax is:
SET SDL_OS2_JOYSTICK=[JOYSTICK_NAME] [AXES] [BUTTONS] [HATS] [BALLS]
So, it you have a Gravis GamePad with 4 axes, 2 buttons, 2 hats and 0 balls,
the line should be:
SET SDL_OS2_JOYSTICK=Gravis_GamePad 4 2 2 0
If you want to add spaces in your joystick name, just surround it with
quotes or double-quotes:
SET SDL_OS2_JOYSTICK='Gravis GamePad' 4 2 2 0
or
SET SDL_OS2_JOYSTICK="Gravis GamePad" 4 2 2 0
Note however that Balls and Hats are not supported under OS/2, and the
value will be ignored... but it is wise to define these correctly because
in the future those can be supported.
Also the number of buttons is limited to 2 when using two joysticks,
4 when using one joystick with 4 axes, 6 when using a joystick with 3 axes
and 8 when using a joystick with 2 axes. Notice however these are limitations
of the Joystick Port hardware, not OS/2.

RISC OS
=======
Requirements:
* RISC OS 3.5 or later.
* [SharedUnixLibrary](http://www.riscos.info/packages/LibraryDetails.html#SharedUnixLibraryarm).
* [DigitalRenderer](http://www.riscos.info/packages/LibraryDetails.html#DRendererarm), for audio support.
* [Iconv](http://www.netsurf-browser.org/projects/iconv/), for `SDL_iconv` and related functions.
Compiling:
----------
Currently, SDL2 for RISC OS only supports compiling with GCCSDK under Linux. Both the autoconf and CMake build systems are supported.
The following commands can be used to build SDL2 for RISC OS using autoconf:
./configure --host=arm-unknown-riscos --prefix=$GCCSDK_INSTALL_ENV --disable-gcc-atomics
make
make install
The following commands can be used to build SDL2 for RISC OS using CMake:
cmake -Bbuild-riscos -DCMAKE_TOOLCHAIN_FILE=$GCCSDK_INSTALL_ENV/toolchain-riscos.cmake -DRISCOS=ON -DCMAKE_INSTALL_PREFIX=$GCCSDK_INSTALL_ENV -DCMAKE_BUILD_TYPE=Release -DSDL_GCC_ATOMICS=OFF
cmake --build build-riscos
cmake --build build-riscos --target install
Current level of implementation
-------------------------------
The video driver currently provides full screen video support with keyboard and mouse input. Windowed mode is not yet supported, but is planned in the future. Only software rendering is supported.
The filesystem APIs return either Unix-style paths or RISC OS-style paths based on the value of the `__riscosify_control` symbol, as is standard for UnixLib functions.
The audio, loadso, thread and timer APIs are currently provided by UnixLib.
GCC atomics are currently broken on some platforms, meaning it's currently necessary to compile with `--disable-gcc-atomics` using autotools or `-DSDL_GCC_ATOMICS=OFF` using CMake.
The joystick, locale and power APIs are not yet implemented.

Using SDL with Microsoft Visual C++
===================================
### by [Lion Kimbro](mailto:snowlion@sprynet.com) with additions by [James Turk](mailto:james@conceptofzero.net)
You can either use the precompiled libraries from the [SDL](https://www.libsdl.org/download.php) web site, or you can build SDL
yourself.
### Building SDL
0. To build SDL, your machine must, at a minimum, have the DirectX9.0c SDK installed. It may or may not be retrievable from
the [Microsoft](https://www.microsoft.com) website, so you might need to locate it [online](https://duckduckgo.com/?q=directx9.0c+sdk+download&t=h_&ia=web).
_Editor's note: I've been able to successfully build SDL using Visual Studio 2019 **without** the DX9.0c SDK_
1. Open the Visual Studio solution file at `./VisualC/SDL.sln`.
2. Your IDE will likely prompt you to upgrade this solution file to whatever later version of the IDE you're using. In the `Retarget Projects` dialog,
all of the affected project files should be checked allowing you to use the latest `Windows SDK Version` you have installed, along with
the `Platform Toolset`.
If you choose *NOT* to upgrade to use the latest `Windows SDK Version` or `Platform Toolset`, then you'll need the `Visual Studio 2010 Platform Toolset`.
3. Build the `.dll` and `.lib` files by right clicking on each project in turn (Projects are listed in the _Workspace_
panel in the _FileView_ tab), and selecting `Build`.
You may get a few warnings, but you should not get any errors.
Later, we will refer to the following `.lib` and `.dll` files that have just been generated:
- `./VisualC/Win32/Debug/SDL2.dll` or `./VisualC/Win32/Release/SDL2.dll`
- `./VisualC/Win32/Debug/SDL2.lib` or `./VisualC/Win32/Release/SDL2.lib`
- `./VisualC/Win32/Debug/SDL2main.lib` or `./VisualC/Win32/Release/SDL2main.lib`
_Note for the `x64` versions, just replace `Win32` in the path with `x64`_
### Creating a Project with SDL
- Create a project as a `Win32 Application`.
- Create a C++ file for your project.
- Set the C runtime to `Multi-threaded DLL` in the menu:
`Project|Settings|C/C++ tab|Code Generation|Runtime Library `.
- Add the SDL `include` directory to your list of includes in the menu:
`Project|Settings|C/C++ tab|Preprocessor|Additional include directories `
*VC7 Specific: Instead of doing this, I find it easier to add the
include and library directories to the list that VC7 keeps. Do this by
selecting Tools|Options|Projects|VC++ Directories and under the "Show
Directories For:" dropbox select "Include Files", and click the "New
Directory Icon" and add the [SDLROOT]\\include directory (e.g. If you
installed to c:\\SDL\\ add c:\\SDL\\include). Proceed to change the
dropbox selection to "Library Files" and add [SDLROOT]\\lib.*
The "include directory" I am referring to is the `./include` folder.
Now we're going to use the files that we had created earlier in the *Build SDL* step.
Copy the following file into your Project directory:
- `SDL2.dll`
Add the following files to your project (It is not necessary to copy them to your project directory):
- `SDL2.lib`
- `SDL2main.lib`
To add them to your project, right click on your project, and select
`Add files to project`.
**Instead of adding the files to your project, it is more desirable to add them to the linker options: Project|Properties|Linker|Command Line
and type the names of the libraries to link with in the "Additional Options:" box. Note: This must be done for each build configuration
(e.g. Release,Debug).**
### Hello SDL2
Here's a sample SDL snippet to verify everything is setup in your IDE:
```
#include "SDL.h"
int main( int argc, char* argv[] )
{
const int WIDTH = 640;
const int HEIGHT = 480;
SDL_Window* window = NULL;

### That's it!
I hope that this document has helped you get through the most difficult part of using the SDL: installing it.
Suggestions for improvements should be posted to the [Github Issues](https://github.com/libsdl-org/SDL/issues).

PS Vita
=======
SDL port for the Sony Playstation Vita and Sony Playstation TV
Credit to
* xerpi, cpasjuste and rsn8887 for initial (vita2d) port
* vitasdk/dolcesdk devs
* CBPS discord (Namely Graphene and SonicMastr)
Building
--------
To build for the PSVita, make sure you have vitasdk and cmake installed and run:
```
cmake -S. -Bbuild -DCMAKE_TOOLCHAIN_FILE=${VITASDK}/share/vita.toolchain.cmake -DCMAKE_BUILD_TYPE=Release
cmake --build build
cmake --install build
```
Notes
-----
* gles1/gles2 support and renderers are disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PVR=ON`
These renderers support 720p and 1080i resolutions. These can be specified with:
`SDL_setenv("VITA_RESOLUTION", "720", 1);` and `SDL_setenv("VITA_RESOLUTION", "1080", 1);`
* gles2 support via PIB is disabled by default and can be enabled by configuring with `-DVIDEO_VITA_PIB=ON`
* By default SDL emits mouse events for touch events on every touchscreen.
Vita has two touchscreens, so it's recommended to use `SDL_SetHint(SDL_HINT_TOUCH_MOUSE_EVENTS, "0");` and handle touch events instead.
Individual touchscreens can be disabled with:
`SDL_setenv("VITA_DISABLE_TOUCH_FRONT", "1", 1);` and `SDL_setenv("VITA_DISABLE_TOUCH_BACK", "1", 1);`
* Support for L2/R2/R3/R3 buttons, haptic feedback and gamepad led only available on PSTV, or when using external ds4 gamepad on vita.
