Ethan Lee ae105ae1 2022-07-10T12:59:33 windows: Move IMMDevice work to common file, implement DirectSound enumeration support
pionere 01bfde45 2022-03-17T12:22:18 simplify SetDSerror - no need to keep the error in a static variable - always print the error code - reduce the required stack-size - reduce the number of snprintf calls (and code size)
pionere a70bb259 2022-01-20T13:16:03 drop handle parameter of OpenDevice
pionere 2eafe434 2022-01-20T12:18:59 cleanup/sync the main loop of *_OpenDevice functions to pick audio format
pionere 1043dd8c 2022-01-19T12:58:04 adjust handling of iscapture - drop iscapture parameter of OpenDevice - use SDL_bool for iscapture
pionere 0dda8a7f 2022-01-17T11:21:01 cleanup init functions of audio - use SDL_bool if possible - assume NULL/SDL_FALSE filled impl - skip zfill of current_audio at the beginning of SDL_AudioInit (done before the init() calls)

Sam Lantinga cb361896 2020-12-09T07:16:22 Fixed bug 5235 - All internal sources should include SDL_assert.h Ryan C. Gordon We should really stick this in SDL_internal.h or something so it's always available.

sezero 40b27fd5 2018-02-12T17:00:00 revert the recent typecast assignment changes (see bug #4079) also change the void* typedefs for the two vulkan function pointers added in vulkan_internal.h into generic function pointer typedefs.
Sam Lantinga 90e72bf4 2018-01-30T18:08:34 Fixed ISO C99 compatibility SDL now builds with gcc 7.2 with the following command line options: -Wall -pedantic-errors -Wno-deprecated-declarations -Wno-overlength-strings --std=c99

Ryan C. Gordon 52827361 2016-11-23T10:51:44 directsound: fixed compiler warnings.
Ryan C. Gordon f6a280ab 2016-10-07T15:13:46 audio: Don't trust audio drivers to drain pending audio. This tends to be a frequent spot where drivers hang, and the waits were often unreliable in any case. Instead, our audio thread now alerts the driver that we're done streaming audio (which currently XAudio2 uses to alert the system not to warn about the impending underflow) and then SDL_Delay()'s for a duration that's reasonable to drain the DMA buffers before closing the device.
Ryan C. Gordon b78ec974 2016-08-10T16:00:16 directsound: Implemented audio capture support.
Ryan C. Gordon 21c7fe00 2016-08-10T15:34:24 windows: directsound should also map audio device GUIDs to proper names. Moved this code from winmm into core so both can use it. DirectSound (at least on Win10) also returns truncated device names, even though it's handed in as a string pointer and not a static-sized buffer. :/
Ryan C. Gordon 7a8e4cb0 2016-08-09T19:35:46 directsound: recalculate audiospec size before creating secondary buffer. I think this was a bug before? Maybe I'm misunderstanding this, but it looks like it was working because we allocate room for 8 chunks...
Ryan C. Gordon 761a7978 2016-08-05T01:59:06 audio: changed some SDL_memset() calls to SDL_zero(), other minor corrections.
Ryan C. Gordon 9b647727 2016-08-05T01:44:41 audio: Clean up some CloseDevice() interface details. - It's now always called if device->hidden isn't NULL, even if OpenDevice() failed halfway through. This lets implementation code not have to clean up itself on every possible failure point; just return an error and SDL will handle it for you. - Implementations can assume this->hidden != NULL and not check for it. - implementations don't have to set this->hidden = NULL when done, because the caller is always about to free(this). - Don't reset other fields that are in a block of memory about to be free()'d. - Implementations all now free things like internal mix buffers last, after closing devices and such, to guarantee they definitely aren't in use anymore at the point of deallocation.

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
Ryan C. Gordon f9cfd9fa 2015-03-18T02:01:17 Bunch of reworking to how we manage audio devices. Device enumeration now happens at startup and then is managed exclusively through hotplugging instead of full redetection. The device name list now has a unique "handle" associated with each item and SDL will pass this to the backend so they don't have to figure out how a human readable name maps to real hardware for a second time. Other cleanups, fixes, improvements, plus all the audio backends updated to the new interface...largely untested at this point, though.
Edward Rudd b88ca1b4 2015-02-10T16:28:56 the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
David Ludwig 70438be2 2014-12-03T10:55:23 WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this!
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam
David Ludwig 3dcb451f 2014-04-09T21:29:19 Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
Ryan C. Gordon faf760d2 2013-08-22T13:32:27 XAudio2/DirectSound: Use the usual Windows string convert (thanks, Norfanin!).
Gabriel Jacobo 552b04c5 2013-08-20T20:34:40 More non C89 compliant comments
Gabriel Jacobo dad42067 2013-08-12T11:13:50 Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
