* Use a busy-wait when synchronizing against the mixerChris Robinson2020-03-161-2/+2
| | | | | | | | The mixer should have higher priority than any thread that can make AL calls, so even on single-core systems, it shouldn't stall the mix. It will, however, return back to the caller as soon as it can, while yielding will give up the timeslice if there's any other thread waiting to process even if the mix is almost done.
* Fix voices being forced to update without valid propertiesChris Robinson2020-03-042-16/+10
| | | | | | | | | | | | | | | | When starting a voice, the source ID was set before its first update struct was provided, creating a small window where a listener or effect slot update could force a voice to update without it having any valid properties to update with. Supplying the update struct first would create a different race, where the mixer could see a voice without a source but with an update struct, causing the update struct to be 'freed' without being applied. The fix here is to provide the update struct before setting the source ID, and change the mixer to ignore update structs for voices without a source ID. This can pseudo-orphan the updates that get set on a voice just as it stops, leaving the struct unusable until the voice is used again, or the voice gets deleted which will clear it. But it allows the update struct to stay in place and get applied once the voice gets a source ID.

* Handle playing voices after disconnectionChris Robinson2020-02-241-5/+11
|
* Improve searching for the next voice when playing multiple sourcesChris Robinson2020-02-241-4/+5
| | | | | Instead of searching from the beginning of the voice list for each source, just continue searching from the last source's voice.
* Ignore VoiceChange objects while disconnectedChris Robinson2020-02-242-1/+34
| | | | | And try to improve ALvoice/VoiceChange handling when attempting to recover a lost device.
* Simplify replaying a sourceChris Robinson2020-02-233-13/+32
|
* Remove AL_SOFT_map_buffer from alffplay and add AL_SOFT_callback_bufferChris Robinson2020-02-231-153/+365
| | | | | | | The former doesn't really help too much since buffers still need to be (re)filled and (de)queued individually. A callback buffer, on the other hand, allows for greater efficiency since it just needs to write into a ring buffer that the mixer will directly read from.
* Fix voice allocation increase amountChris Robinson2020-02-221-1/+1
|
* Remove a couple unnecessary type aliasesChris Robinson2020-02-223-5/+3
|
* Avoid a single function call in a loopChris Robinson2020-02-211-68/+66
|
* Use an array of ALvoice pointers for the active voicesChris Robinson2020-02-215-112/+130
| | | | | | This allows growing the array atomically with the mixer since the ALvoice objects themselves don't move, and a new larger array of them can be swapped in without blocking the mixer.
* Set the voice's property update after the source IDChris Robinson2020-02-211-3/+3
| | | | Otherwise the mixer has a chance to throw it out before realizing it's needed.

| | | | Pending/asynchronous stops to be implemented soon.

* Flag the voice as callback-based when given a callback bufferChris Robinson2020-02-171-1/+7
|
* Don't bother looping the calculated source offsetChris Robinson2020-02-171-14/+6
| | | | | The offset shouldn't be in a non-wrapped state when playing, and when not playing it's always 0 anyway.
* Don't allow setting a source offset for a callbackChris Robinson2020-02-171-0/+6
|
* Handle running the buffer callback in the voiceChris Robinson2020-02-175-25/+83

* Add a callback flag for voicesChris Robinson2020-02-172-6/+17
|
* Prevent queueing a callback bufferChris Robinson2020-02-171-3/+10
| | | | Also prevent setting it on multiple sources
