* Provide asynchronous property updates for sourcesChris Robinson2016-05-141-11/+37
| | | | | | | | | | | | | | | | | | | | | | | | | This necessitates a change in how source updates are handled. Rather than just being able to update sources when a dependent object state is changed (e.g. a listener gain change), now all source updates must be proactively provided. Consequently, apps that do not utilize any deferring (AL_SOFT_defer_updates or alcSuspendContext/alcProcessContext) may utilize more CPU since it'll be filling out more update containers for the mixer thread to use. The upside is that there's less blocking between the app's calling thread and the mixer thread, particularly for vectors and other multi-value properties (filters and sends). Deferring behavior when used is also improved, since updates that shouldn't be applied yet are simply not provided. And when they are provided, the mixer doesn't have to ignore them, meaning the actual deferring of a context doesn't have to synchrnously force an update -- the process call will send any pending updates, which the mixer will apply even if another deferral occurs before the mixer runs, because it'll still be there waiting on the next mixer invocation. There is one slight bug introduced by this commit. When a listener change is made, or changes to multiple sources while updates are being deferred, it is possible for the mixer to run while the sources are prepping their updates, causing some of the source updates to be seen before the other. This will be fixed in short order.
* Store the remaining context properties with the listener propertiesChris Robinson2016-05-131-6/+4
|
* Use a lockless method for updating listener and context propertiesChris Robinson2016-05-111-6/+21
| | | | | | | | | | | This uses a separate container to provide the relevant properties to the internal update method, using atomic pointer swaps. A free-list is used to avoid having too many individual containers. This allows the mixer to update the internal listener properties without requiring the lock to protect against async updates. It also allows concurrent read access to the user-facing property values, even the multi-value ones (e.g. the vectors).
* Remove the MIDI codeChris Robinson2015-10-201-96/+0
| | | | | | | The extension's not going anywhere, and it can't do anything fluidsynth can't. The code maintenance and bloat is not worth keeping around, and ideally the AL API would be able to facilitate MIDI-like behavior anyway (envelopes, start-at- time, etc).
* Avoid the ALCdevice_Lock/Unlock wrapper in some placesChris Robinson2014-11-011-2/+3
|
* Make alcSuspendContext and alcProcessContext batch updatesChris Robinson2014-10-121-72/+2
| | | | | | | | | | This behavior better matches Creative's hardware drivers and Rapture3D's OpenAL driver. A compatibility environment variable is provided to restore the old no-op behavior for any app that behaves badly from this change (set __ALSOFT_SUSPEND_CONTEXT to "ignore"). If too many apps have a problem with this, the default behavior may need to be changed to ignore, with the env var providing an option to defer/batch instead.

* Use a RWLock to help protect the source's buffer queueChris Robinson2014-05-101-0/+4
| | | | | In some instances this allows to to remove the device/mixer lock, or reduce how long it's held.

* Add a method to set and get soundfontsChris Robinson2013-12-271-4/+48
| | | | | The main purpose of this is to select soundfonts for playback, eventually, instead of the existing method that takes a filename.

* Rename VCALL and VCALL0 to V and V0Chris Robinson2013-11-021-1/+1
|
* Modify how VCALL is handledChris Robinson2013-10-281-1/+1
| | | | | | | | | | | Now instead of specifying the arguments as a third argument to the macro, like VCALL(object,function,(arg1, arg2)); they are specified separately after the macro, like VCALL(object,function)(arg1, arg2); Also, VCALL_NOARGS has been removed in favor of VCALL0, which behaves like above but expects an empty argument list (a separate macro is needed to work around preprocessor limitations).
