Ryan C. Gordon f6eb4b07 2022-04-26T13:14:15 pulseaudio: Feed audio data in response to write callbacks. Instead of waiting until the entire buffer from the SDL callback is ready to be accepted by PulseAudio, we use pa_stream_set_write_callback and feed some portion of the buffer as callbacks come in asking for more. This lets us remove the halving of the buffer size during device open, and also (hopefully) solves several strange hangs that happen in unusual circumstances. Fixes #4387 Fixes #2262
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)

Ryan C. Gordon d713a680 2021-11-25T22:32:40 pulseaudio: wait until at least 1/8th (!) of the mixbuffer is available. This is to workaround systems where we hang in playback because the buffer does not report the space for whatever reason. The system will instead block in PlayDevice, which always immediately follows WaitDevice in modern times so this works out, and it seems to keep the device moving forward. For a future revision, we are either going to clean this up more properly, or attempt to move to PulseAudio's pa_stream_set_write_callback() API, but this will do for SDL 2.0.18. Reference #4387 for discussion and further information.
David Gow a1ffeda0 2021-08-28T22:52:13 Add SDL_HINT_APP_NAME and DBUS inhibition hint See SDL bug #4703. This implements two new hints: - SDL_APP_NAME - SDL_SCREENSAVER_INHIBIT_ACTIVITY_NAME The former is the successor to SDL_HINT_AUDIO_DEVICE_APP_NAME, and acts as a generic "application name" used both by audio drivers and DBUS screensaver inhibition. If SDL_AUDIO_DEVICE_APP_NAME is set, it will still take priority over SDL_APP_NAME. The second allows the "activity name" used by org.freedesktop.ScreenSavver's Inhibit method, which are often shown in the UI as the reason the screensaver (and/or suspend/other power-managment features) are disabled.
Ryan C. Gordon 9504bb12 2021-08-23T00:47:25 pulseaudio: Fix some function signatures that expect const pointers. This might have changed at some point in the Pulse API, or this might have always been wrong, but we didn't notice because the dynamic loading code hides it by casting things to void *. The static path, where it assigns the function pointer directly, puts out a clear compiler warning, though.
Ryan C. Gordon 736a424f 2021-07-27T13:12:57 pulseaudio: Optionally add "monitor" sources to device list. There's a new hint to enable this. Fixes #2917.
Ethan Lee 67e8522d 2021-02-27T17:37:25 Add SDL_GetAudioDeviceSpec. This API is supported by pipewire, pulseaudio, coreaudio, wasapi, and disk.
Oschowa 08547adb 2021-02-20T09:28:03 pulseaudio: Add "zerocopy" playback path
Romain Roffé ef85ed93 2021-02-17T20:53:35 pulseaudio: Initialize fragsize to fix mic recording fragsize wasn't initialized, and it is used for recording. If the value was 0 or -1, pulseaudio configures it itself. But sometimes we can get a random (and large) value that makes pulseaudio give us large sample at a very low frequency. https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/blob/master/src/pulse/def.h#L453 https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/blob/v13.0/src/pulsecore/protocol-native.c#L409

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.
Alistair Leslie-Hughes a69c61fb 2020-08-14T12:08:58 Only assign context and mainloop once we have connected successfully If we fail to connect to the the pa server, we have an assigned context and mainloop that isn't connected. So, when PULSEAUDIO_pa_context_disconnect is called, pa asserts and crashes the application. Assertion 'pa_atomic_load(&(c)->_ref) >= 1' failed at pulse/context.c:1055, function pa_context_disconnect(). Aborting.
Ryan C. Gordon 8601996f 2020-05-03T22:13:48 hints: Allow specifying audio device metadata. This is only supported on PulseAudio. You can set a description when opening your audio device that will show up in pauvcontrol, which lets you set per-stream volume levels. Fixes Bugzilla #4801.

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 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.
Ryan C. Gordon 979de761 2016-08-05T01:44:15 audio: Removed internal SDL_audiomem.h and macros. I think this was important for SDL 1.2 because some targets needed special device memory for DMA buffers or locked memory buffers for use in hardware interrupts or something, but since it just defines to SDL_malloc and SDL_free now, I took it out for clarity's sake.
Ryan C. Gordon d662bc04 2016-08-02T13:50:58 pulseaudio: Implemented audio capture support!
Ryan C. Gordon 6d5c9c1e 2016-08-02T13:48:52 audio: Made some SDL_AudioDevice fields atomic. This makes sure they're properly communicated to the audio threads.
Ryan C. Gordon 9b4db2b8 2016-04-12T18:11:36 Patched to compile on various platforms.
Ryan C. Gordon c61675dc 2016-04-12T16:45:10 threads: Move SDL's own thread creation to a new internal API. This allows us to set an explicit stack size (overriding the system default and the global hint an app might have set), and remove all the macro salsa for dealing with _beginthreadex and such, as internal threads always set those to NULL anyhow. I've taken some guesses on reasonable (and tiny!) stack sizes for our internal threads, but some of these might turn out to be too small in practice and need an increase. Most of them are simple functions, though.

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 cafd030b 2015-03-19T22:08:12 PulseAudio: Hotplug support!
Ryan C. Gordon 7c4b88f2 2015-03-18T10:29:04 PulseAudio: Improved multidevice support. Added capture device enumeration, report human-readable device name, other cleanups.
Ryan C. Gordon 43674503 2015-03-18T10:05:36 Patched to compile on C89 compilers.
Ryan C. Gordon 9a83151e 2015-03-18T09:59:22 PulseAudio: Added multiple device support, other cleanups. Thanks to Dominik Frizel for most of the effort on this! Fixes Bugzilla #2730.
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.
Ryan C. Gordon 0e02ce08 2015-03-16T02:11:39 Initial work on audio device hotplug support. This fills in the core pieces and fully implements it for Mac OS X. Most other platforms, at the moment, will report a disconnected device if it fails to write audio, but don't notice if the system's device list changed at all.
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.
Sam Lantinga 08fa8da7 2013-10-20T21:56:15 Fixed bug 2129 - fix for bug 2121 breaks linking for mingw and throws multiple warnings Andreas Ertelt The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/5486e579872e / https://bugzilla.libsdl.org/show_bug.cgi?id=2121) The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple warning: always_inline function might not be inlinable [-Wattributes] as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.
Sam Lantinga f79fc33a 2013-08-29T08:29:21 Christoph Mallon: Remove pointless if (x) before SDL_free(x)
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.
