dc62fec5	2022-05-20T21:07:25	audio: Fix locking in backends that manage their own callback threads. Otherwise you might get a race where an app pauses the device, but the audio callback still manages to run after the pause is in place.
501a4991	2022-05-05T18:44:32	Add clang-format on/off comments where necessary. Comments were added in places where INDENT-ON/OFF comments are. Places like stdlib's asm don't need it as clang-format doesn't try to indent it.

29694869	2022-04-28T15:56:52	audio: Revert one of the resampler optimizations. This is the one that splits the "left wing" into two for loops to bubble out the conditional that decides if it should read from the left padding or the input buffer. I still believe the optimization is good, but the basic logic of it was incorrect, and needs to be reexamined and fixed before going back into revision control.
5066910b	2022-04-10T13:44:01	audio: Make pregenerated resampler kaiser filter more precise.
111c3add	2022-04-10T13:23:51	audio: Resampler optimizations. - Calculate `j * RESAMPLER_SAMPLES_PER_ZERO_CROSSING` once per loop iteration since we use it multiple times. - Do the left-wing loop in two sections: while `srcframe < 0` and then the remaining calculations when `srcframe >= 0`. This bubbles a conditional out of every iteration of a tight loop, giving us a boost. We could _probably_ do this to the right-wing loop too, but it's less straightforward there. - The real win: Use floats instead of doubles. This almost doubles the speed of the entire function on Intel CPUs, and for embedded things without hardware-level support for doubles, the speedup is enormous. This in theory might reduce audio quality, though, and I had to put a check in place to avoid a division-by-zero that we avoided at higher precision, but this is likely to be worth keeping for at least the Sony PSP and other smaller platforms, if not everyone.
de019568	2022-04-09T23:43:57	audio: Prebake the resampler's kaiser table instead of doing it at runtime.
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
9e264b92	2022-04-18T09:20:47	Certain audio drivers, like the RME "Pro" Audio driver, have resampling quality issues when using WASAPI. We'll use SDL's resampling algorithm so we have consistent quality between platforms and drivers. Fixes https://github.com/libsdl-org/SDL/issues/5538

5b36a527	2022-02-08T12:30:28	audio: pipewire: Remove redundant locks The io_list_check_add() and io_list_remove() functions are only ever called from within the Pipewire thread loop, so the locks are redundant. io_list_sort() is called from within a lock in the device detection function, so those additional locks are redundant as well.
48b4d1c4	2022-02-08T12:20:52	audio: pipewire: Convert atomic hotplug conditional variables to SDL_bool The hotplug loop condition variables are always guarded by the loop mutex while the loop is running, so they don't need to be atomic.
53091e36	2022-02-02T12:30:34	audio: pipewire: Remove the hard upper bound on rates and buffer sizes Remove the hard upper limit of 8192 samples and instead use the buffer sizes provided by Pipewire to determine the size of the intermediate input buffer and whether double buffering is required for output streams. This allows for higher latency streams to potentially avoid double-buffering in the output case, and we can guarantee that the intermediate input buffer will always be large enough to handle whatever Pipewire may deliver. As the buffer size calculations occur in a callback in the Pipewire processing thread itself, the stream readiness check has been modified to wait on two distinct flags set when the buffers have been configured and when the stream is ready and running.
66866249	2022-02-02T11:09:02	audio: pipewire: Condition variable doesn't need to be atomic The condition variable is guarded by a mutex, so no need for it to be atomic.
0b34f180	2022-01-30T12:00:55	audio: pipewire: Don't double free properties on init failure The context and stream creation functions will destroy the passed properties object on failure, so no need to do it manually. The pw_properties_free() function pointer is no longer needed, so it can be removed.

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.

3bf7994f	2021-09-27T14:38:12	Add and use `SDL_FALLTHROUGH` for fallthroughs Case fallthrough warnings can be suppressed using the __fallthrough__ compiler attribute. Unfortunately, not all compilers have this attribute, or even have __has_attribute to check if they have the __fallthrough__ attribute. [[fallthrough]] is also available in C++17 and the next C2x, but not everyone uses C++17 or C2x. So define the SDL_FALLTHROUGH macro to deal with those problems - if we are using C++17 or C2x, it expands to [[fallthrough]]; else if the compiler has __has_attribute and has the __fallthrough__ attribute, then it expands to __attribute__((__fallthrough__)); else it expands to an empty statement, with a /* fallthrough / comment (it's a do {} while (0) statement, because users of this macro need to use a semicolon, because [[fallthrough]] and __attribute__((__fallthrough__)) require a semicolon). Clang before Clang 10 and GCC before GCC 7 have problems with using __attribute__ as a sole statement and warn about a "declaration not declaring anything", so fall back to using the / fallthrough / comment if we are using those older compiler versions. Applications using SDL are also free to use this macro (because it is defined in begin_code.h). All existing / fallthrough */ comments have been replaced with this macro. Some of them were unnecessary because they were the last case in a switch; using SDL_FALLTHROUGH in those cases would result in a compile error on compilers that support __fallthrough__, for having a __attribute__((__fallthrough__)) statement that didn't immediately precede a case label.
abc12a83	2021-11-11T15:58:44	Revert "Add and use `SDL_FALLTHROUGH` for fallthroughs" This reverts commit 66a08aa3914a98667f212e79b4f0b9453203d656. This causes problems with older compilers: https://github.com/libsdl-org/SDL/pull/4791#issuecomment-966630997

But for many cases, that is likely complete sufficient. In either case, this cleaned up the code to no longer need a semaphore at startup. Fixes #4862.

2423c514	2021-10-13T09:33:51	Work around hang in AAudioStream_write() during extended shared object loading while running in a debugger. Observed on a OnePlus 8T (KB2005) running Oxygen OS 11.0.10.10.KB05AA. The observed behavior is that any nonzero timeout value would hang until the device was paused and resumed. And a zero timeout value would always return 0 frames written even when audio fragments could be heard. Making a manual timeout system unworkable. None of the straightforward systems imply that there's a detectable problem before the call to AAudioStream_write(). And the callback set within AAudioStreamBuilder_setErrorCallback() does not get called as we enter the hang state. I've found that AAudioStream_getTimestamp() will report an error state from another thread. So this change codifies that behavior a bit until a better fix or more root cause can be found.

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.
7d90df0e	2021-08-29T15:24:23	Restore previous behavior of empty SDL_AUDIODRIVER trying all drivers. The recent change to make SDL_AUDIODRIVER support comma-separated lists broke the previous behavior where an SDL_AUDIODRIVER that was empty behaved the same as if it was not set at all. This old behavior was necessary to paper over differences in platforms where SDL_setenv may or may not actually delete the env var if an empty string is specified. This patch just adds a simple check to ensure SDL_AUDIODRIVER is not empty before using it, restoring the old interpretation of the empty var.
3261f7f6	2021-08-26T16:15:30	audio: Support "pulse" as an alias for "pulseaudio" Originally, SDL 1.2 used "pulse" as the name for its PulseAudio driver. While it now supports "pulseaudio" as well for compatibility with SDL 2.0 [1], there are still scripts and distro packages which set SDL_AUDIODRIVER=pulse [2]. While it's possible to remove this in most circumstances or replace it with "pulseaudio" or a comma-separated list, this may still conflict if the environment variable is set globally and old binary builds of SDL 1.2 (e.g. packaged with older games) are being used. To fix this on SDL 2.0, add a hardcoded check for "pulse" as an audio driver name, and replace it with "pulseaudio". This mimics what SDL 1.2 does (but in reverse). Note that setting driver_attempt{,_len} is safe here as they're reset correctly based on driver_attempt_end on the next loop. [1] https://github.com/libsdl-org/SDL-1.2/commit/d9514097846381cd30fe08df65dbdd48de92a058 [2] https://bugzilla.opensuse.org/show_bug.cgi?id=1189778

Don't use "#pragma clang attribute" since it is only available in relatively recent versions, there's no obvious way to check if it's supported, and just using __attribute__ directly (for gcc as well) results in simpler code anyway.

audio: Revert one of the resampler optimizations. This is the one that splits the "left wing" into two for loops to bubble out the conditional that decides if it should read from the left padding or the input buffer. I still believe the optimization is good, but the basic logic of it was incorrect, and needs to be reexamined and fixed before going back into revision control.

audio: Resampler optimizations. - Calculate `j * RESAMPLER_SAMPLES_PER_ZERO_CROSSING` once per loop iteration since we use it multiple times. - Do the left-wing loop in two sections: while `srcframe < 0` and then the remaining calculations when `srcframe >= 0`. This bubbles a conditional out of every iteration of a tight loop, giving us a boost. We could _probably_ do this to the right-wing loop too, but it's less straightforward there. - The real win: Use floats instead of doubles. This almost doubles the speed of the entire function on Intel CPUs, and for embedded things without hardware-level support for doubles, the speedup is enormous. This in theory might reduce audio quality, though, and I had to put a check in place to avoid a division-by-zero that we avoided at higher precision, but this is likely to be worth keeping for at least the Sony PSP and other smaller platforms, if not everyone.

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

audio: pipewire: Remove the hard upper bound on rates and buffer sizes Remove the hard upper limit of 8192 samples and instead use the buffer sizes provided by Pipewire to determine the size of the intermediate input buffer and whether double buffering is required for output streams. This allows for higher latency streams to potentially avoid double-buffering in the output case, and we can guarantee that the intermediate input buffer will always be large enough to handle whatever Pipewire may deliver. As the buffer size calculations occur in a callback in the Pipewire processing thread itself, the stream readiness check has been modified to wait on two distinct flags set when the buffers have been configured and when the stream is ready and running.

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.

Add and use `SDL_FALLTHROUGH` for fallthroughs Case fallthrough warnings can be suppressed using the __fallthrough__ compiler attribute. Unfortunately, not all compilers have this attribute, or even have __has_attribute to check if they have the __fallthrough__ attribute. [[fallthrough]] is also available in C++17 and the next C2x, but not everyone uses C++17 or C2x. So define the SDL_FALLTHROUGH macro to deal with those problems - if we are using C++17 or C2x, it expands to [[fallthrough]]; else if the compiler has __has_attribute and has the __fallthrough__ attribute, then it expands to __attribute__((__fallthrough__)); else it expands to an empty statement, with a /* fallthrough */ comment (it's a do {} while (0) statement, because users of this macro need to use a semicolon, because [[fallthrough]] and __attribute__((__fallthrough__)) require a semicolon). Clang before Clang 10 and GCC before GCC 7 have problems with using __attribute__ as a sole statement and warn about a "declaration not declaring anything", so fall back to using the /* fallthrough */ comment if we are using those older compiler versions. Applications using SDL are also free to use this macro (because it is defined in begin_code.h). All existing /* fallthrough */ comments have been replaced with this macro. Some of them were unnecessary because they were the last case in a switch; using SDL_FALLTHROUGH in those cases would result in a compile error on compilers that support __fallthrough__, for having a __attribute__((__fallthrough__)) statement that didn't immediately precede a case label.

Work around hang in AAudioStream_write() during extended shared object loading while running in a debugger. Observed on a OnePlus 8T (KB2005) running Oxygen OS 11.0.10.10.KB05AA. The observed behavior is that any nonzero timeout value would hang until the device was paused and resumed. And a zero timeout value would always return 0 frames written even when audio fragments could be heard. Making a manual timeout system unworkable. None of the straightforward systems imply that there's a detectable problem before the call to AAudioStream_write(). And the callback set within AAudioStreamBuilder_setErrorCallback() does not get called as we enter the hang state. I've found that AAudioStream_getTimestamp() will report an error state from another thread. So this change codifies that behavior a bit until a better fix or more root cause can be found.

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.

Restore previous behavior of empty SDL_AUDIODRIVER trying all drivers. The recent change to make SDL_AUDIODRIVER support comma-separated lists broke the previous behavior where an SDL_AUDIODRIVER that was empty behaved the same as if it was not set at all. This old behavior was necessary to paper over differences in platforms where SDL_setenv may or may not actually delete the env var if an empty string is specified. This patch just adds a simple check to ensure SDL_AUDIODRIVER is not empty before using it, restoring the old interpretation of the empty var.

audio: Support "pulse" as an alias for "pulseaudio" Originally, SDL 1.2 used "pulse" as the name for its PulseAudio driver. While it now supports "pulseaudio" as well for compatibility with SDL 2.0 [1], there are still scripts and distro packages which set SDL_AUDIODRIVER=pulse [2]. While it's possible to remove this in most circumstances or replace it with "pulseaudio" or a comma-separated list, this may still conflict if the environment variable is set globally and old binary builds of SDL 1.2 (e.g. packaged with older games) are being used. To fix this on SDL 2.0, add a hardcoded check for "pulse" as an audio driver name, and replace it with "pulseaudio". This mimics what SDL 1.2 does (but in reverse). Note that setting driver_attempt{,_len} is safe here as they're reset correctly based on driver_attempt_end on the next loop. [1] https://github.com/libsdl-org/SDL-1.2/commit/d9514097846381cd30fe08df65dbdd48de92a058 [2] https://bugzilla.opensuse.org/show_bug.cgi?id=1189778
