b5483f2c	2022-12-01T18:03:36	Fix formatting on Wayland and Pipewire function signatures Fixes the formatting on some function signatures that clang-format missed. (cherry picked from commit 378b1c286a9c3206e827a47f0147384e92c4c2b2)
d0bbfdbf	2022-12-01T16:07:03	Clang-Tidy fixes (#6725) (cherry picked from commit 3c501b963dd8f0605a6ce7978882df39ba76f9cd)
b8d85c69	2022-11-30T12:51:59	Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)

37aecda2	2022-07-14T11:38:51	pipewire: Use PW_KEY_TARGET_OBJECT to specify stream connection nodes Pipewire 0.3.44 introduced PW_KEY_TARGET_OBJECT, which is to be used to specify target connection nodes for streams. This parameter takes either a node path (PW_KEY_NODE_NAME) or serial number (PW_KEY_OBJECT_SERIAL) to specify a target node. The former is used in this case since the path is already being retrieved and stored for other purposes. The target_id parameter in pw_stream_connect() is now deprecated and should always be PW_ID_ANY when PW_KEY_TARGET_OBJECT is used.
36d8460c	2022-07-11T16:59:23	pipewire: Dynamically allocate the buffer for node strings Calculate and allocate the buffer for the IO node name and path strings dynamically instead of using arbitrary sized static buffers.

60da11f0	2022-07-11T14:31:20	pipewire: Remove deprecated configuration key With Pipewire now requiring a minimum version 0.3.24, the PW_KEY_CONTEXT_PROFILE_MODULES value is no longer required for legacy compatability and can be safely removed.

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.

9da9e85c	2022-02-08T12:59:01	audio: pipewire: Reset all hotplug values and pointers on shutdown Ensure that all hotplug variables and pointers are reset to NULL or their original value when shutting down.
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.

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.

8deb4063	2021-03-28T17:22:59	audio: pipewire: Avoid redundant locking The pw_thread_loop already locks and unlocks the thread mutex at the start and end of each loop iteration, so these locks are unnecessary.
5bb2bbd4	2021-03-28T17:17:00	audio: pipewire: Don't use uninitialized variables in callbacks Some of the SDL_AudioDevice struct members aren't initialized until after returning from the OpenDevice function. Since Pipewire uses it's own processing threads, the callbacks can be entered before all members of SDL_AudioDevice are initialized, such as work_buffer, callbackspec and the processing stream, which creates a race condition. Don't use these members when in the paused state to avoid potentially using uninitialized values and memory.
4fbd60b8	2021-03-09T12:22:48	audio: pipewire: Remove the nickname portion of sink/source names Removes the node nickname from sink/source nodes as it doesn't provide any useful information and names now match those used in Pulseaudio, so any stored configuration data will be compatible between the two audio backends.

9afd7570	2021-02-20T13:33:12	audio: pipewire: Always buffer source audio The latency of source nodes can change depending on the overall latency of the processing graph. Incoming audio must therefore always be buffered to ensure uninterrupted delivery. The SDL_AudioStream path was removed in the input callback as the only thing it was used for was buffering audio outside of Pipewire's min/max period sizes, and that case is now handled by the omnipresent buffer.
106dc009	2021-02-19T17:18:36	audio: pipewire: Pass proper parameter to user audio callback The audio callbacks should pass the callbackspec.userdata parameter to the callback, not spec.userdata Co-authored-by: Oschowa <Oschowa@web.de>
f3ebbc06	2021-02-19T16:02:20	audio: pipewire: Retrieve the channel count and default sample rate for sinks/sources Extend device enumeration to retrieve the channel count and default sample rate for sink and source nodes. This required a fairly significant rework of the enumeration procedure as multiple callbacks are involved now. Sink/source nodes are tracked in a separate list during the enumeration process so they can be cleaned up if a device is removed before completion. These changes also simplify any future efforts that may be needed to retrieve additional configuration information from the nodes.

The SDL_AudioStream path was removed in the input callback as the only thing it was used for was buffering audio outside of Pipewire's min/max period sizes, and that case is now handled by the omnipresent buffer.

audio: pipewire: Pass proper parameter to user audio callback The audio callbacks should pass the callbackspec.userdata parameter to the callback, not spec.userdata Co-authored-by: Oschowa <Oschowa@web.de>

audio: pipewire: Retrieve the channel count and default sample rate for sinks/sources Extend device enumeration to retrieve the channel count and default sample rate for sink and source nodes. This required a fairly significant rework of the enumeration procedure as multiple callbacks are involved now. Sink/source nodes are tracked in a separate list during the enumeration process so they can be cleaned up if a device is removed before completion. These changes also simplify any future efforts that may be needed to retrieve additional configuration information from the nodes.
