The new OpenGL ES 2.0 YUV Texture support does not correctly display padded, non-contiguous YUV data.
I am using SDL2 95bd3d33482e (as provided by 'hg id --id') from Mercurial.
The YUV data I am using is provided by the FFMPEG family of libraries. According to FFMPEG's documentation, "The linesize [pitch] may be larger than the size of usable data -- there may be extra padding present for performance reasons."
The dimensions of the video file that I am using are 480x360. What I get from FFMPEG is a Ypitch of 512, and Upitch and Vpitch are both 256.
When I pack new Y, U and V buffers with only the "usable" data (Ypitch is 480 and Upitch and Vpitch are both 240), and use those new buffers, the image is display correctly.
It appears that the Ypitch, Upitch and Vpitch parameters are not being used by SDL_UpdateYUVTexture().
I use SDL_PIXELFORMAT_YV12 for my YUV texture, however, the same results are seen when I use SDL_PIXELFORMAT_IYUV.
Not sure if this is related or not, but when I render the YUV texture (padded and unpadded) to a RGB24 texture, the resulting image is greyscale (or could by just the Y channel).
The URL field for this bug entry is set to my email (SDL mailing list archive) which includes an example image of what I see when rendering padded, non-contiguous YUV data.

On systems with vsnprintf call SDL_SetError fails when passed a NULL as an argument. SDL's implementation checks for NULL (as seen in the commit: https://hg.libsdl.org/SDL/rev/835403a6aec8), but system implementation may crash.

Fix win32 build which was failing due to missing PRIs64.
This change adds definitions for the C99 PRIs16 and PRIu64
which are missing from <stdint.h> on at last win32 and
possibly other platforms.
These already existed in testgesture.c so I removed them
from there also.
Add V=1 to the make command line will show the full commands but by default
we just show the tool-type and the output file. This is generally much easier
on the eye and makes warnings and errors more clearly visible.

If you play with the TouchScreen with +3 fingers randomly / pressing simultaneously all fingers.
You triggers FINGER DOWN events, but not always all the associated FINGER UP events.
So, after a while SDL_GetNumFingers() can report a wrong number of fingers pressed !
The explanation is hidden there : http://developer.android.com/reference/android/view/MotionEvent.html
Each pointer has a unique id that is assigned when it first goes down (indicated by ACTION_DOWN or ACTION_POINTER_DOWN).
A pointer id remains valid until the pointer eventually goes up (indicated by ACTION_UP or ACTION_POINTER_UP) or when the gesture is canceled (indicated by ACTION_CANCEL).
in ACTION_CANCEL :
The current gesture has been aborted. You will not receive any more points in it. You should treat this as an up event, but not perform any action that you normally would.
Constant Value: 3 (0x00000003)

Local files that are dropped onto a window under X11
are not going through a URI decoding step, resulting in the following
in my test application:
Dropped file /home/meklu/Pictures/Screenshot%20from%202013-10-30%2014:04:50.png
Couldn't load /home/meklu/Pictures/Screenshot%20from%202013-10-30%2014:04:50.png
Expected result:
Dropped file /home/meklu/Pictures/Screenshot from 2013-10-30 14:04:50.png
Loaded /home/meklu/Pictures/Screenshot from 2013-10-30 14:04:50.png successfully
I've attached a patch that fixes the issue by doing URI decoding in-place on
the file string buffer.

The GL Renderer current context tracking fails when one window is used with an SDL renderer but another separate window is used with a user handled OpenGL context.
Attached is a small program that reproduces this bug, at least in some Linux machines where an OpenGL renderer is provided by default.
Expected Output:
-"First window" should be blue.
-"Second window" should be green.
Gotten Output:
- "First window" black.
- "Second window" blue.
What happened:
The renderer created for the "first window" ends rendering into the "second window" OpenGL context.
Bug location:
SDL_render_gl.c - line 286 on hg:
static SDL_GLContext SDL_CurrentContext = NULL;
When making SDL_GL_MakeCurrent from the user perspective, that variable or the GL renderer is not notified about the OpenGL context change.
Solution proposal:
- Move the current GL context cache into another place global.

If you #define NO_SDL_GLEXT before including SDL_opengl.h, it still includes the platform-provided glext.h. The comments indicate that this define is intended to be used when you provide your own glext.h (quote from SDL_opengl.h: "Define this if you have your own version of glext.h and want to disable the version included in SDL_opengl.h.")
This is a problem because glext.h depends on the contents of gl.h, and it's practical to let SDL_opengl.h pick the right #include for gl.h for our platform.

The Xcode Instruments Leak tool reports a leak from IODisplayCreateInfoDictionary in Cocoa_GetDisplayName.
This happened after upgrading to Xcode 5.

Add a gamepad mapping entry for Bluetooth DualShock 4 controllers on Linux.
The button mapping is the same as the USB controller, but the GUID is
different.

if the variable NDK_MODULE_PATH is set to a relative path (like "../"),
compiling of a static SDL lib fails with an error similar to this:
make: *** No rule to make target
`..//android_libs/SDL/..//android_libs/SDL/src/main/android/SDL_android_main.c',
needed by
`obj/local/armeabi/objs/SDL2_static/__//android_libs/SDL/src/main/android/SDL_android_main.o'.
Stop.
Regarding the shared lib, this is already prevented by a "subst" command
in the /Android.mk, which removes all occurences of "$(LOCAL_PATH)/".
The attached patch does the same with the additional
"SDL_android_main.c", which is included for build the static SDL lib.
Added missing files to SDL2 project
Added missing Visual Studio 2008 tests to the solution
Added output paths which match the 2010+ projects
Added SDL project references instead of old style project dependencies
Removed post-build copy step and added data files to projects
It was simpler to just have the polling (actually: hotplug detection)
functions return immediately if it's not an appropriate time to poll.
Note that previously, if any joystick/controller was opened, we would poll
every time anyhow, skipping this function.
