|
* Use a semaphore to signal the event handlerChris Robinson2018-02-012-3/+4
| | | | | | | | | | | Semaphores allow for semi-persistent signals, compared to a condition variable which requires a mutex for proper detection. A semaphore can be 'post'ed after writing some data on one thread, and another thread will be able to recognize it quickly even if the post occured in between checking for data and waiting. This more correctly fixes a race condition with events since the mixer shouldn't be using mutexes, and arbitrary wake-ups just to make sure an event wasn't missed was quite inefficient.
* Send buffer completed events when enabledChris Robinson2018-02-012-11/+38
|
* Add a thread to marshal events from the mixerChris Robinson2018-01-311-1/+19
| | | | | | To avoid having unknown user code running in the mixer thread that could significantly delay the mixed output, a lockless ringbuffer is used for the mixer to provide events that a secondary thread will pop off and process.
* Rename EventLock to make it more clear it's protecting the callbackChris Robinson2018-01-301-2/+2

* Don't bother with an explicit stop backend methodChris Robinson2018-01-2918-348/+209

* Store effects in an array of listsChris Robinson2018-01-271-10/+12
|
* Use a vector to store the effect slot pointersChris Robinson2018-01-271-12/+13
| | | | And make the ID a simple index into it (1-base, to avoid ID 0).
* Use an array lookup for source IDsChris Robinson2018-01-271-37/+48
| | | | | This is now similar to buffers, being stored in groups of 64 in a vector with the ID providing the array indices.
* Use a different method for storing and looking up buffersChris Robinson2018-01-271-10/+12
| | | | | | | | | | | | | | | | | Rather than each buffer being individually allocated with a generated 'thunk' ID that's used with a uint:ptr map, buffers are allocated in arrays of 64 within a vector. Each group of 64 has an associated 64-bit mask indicating which are free to use, and the buffer ID is comprised of the two array indices which directly locate the buffer (no searching, binary or otherwise). Currently no buffers are actually deallocated after being allocated, though they are reused. So an app that creates a ton of buffers once, then deletes them all and uses only a couple from then on, will have a bit of waste, while an app that's more consistent with the number of used buffers won't be a problem. This can be improved by removing elements of the containing vector that contain all-free buffers while there are plenty of other free buffers. Also, this method can easily be applied to other resources, like sources.
* Don't rely on alMain.h in alBuffer.hChris Robinson2018-01-261-0/+78

* Construct error messages using parameterized valuesChris Robinson2018-01-259-170/+176

* Report AL_SOFTX_events as an in-progress extensionChris Robinson2018-01-241-0/+1

* Add a deprecated event type for alDopplerVelocityChris Robinson2018-01-241-0/+1

* Provide messages for the remaining AL errorsChris Robinson2018-01-249-261/+188
|
* Handle event propertiesChris Robinson2018-01-231-0/+18
| | | | | This just implements the event methods insofar as tracked state. No events are generated/reported yet.
* Use a new proper buffer function with a flags parameterChris Robinson2018-01-231-0/+4
| | | | | | Rather than hackily combining bit flags with the format, to increase the number of potential flags. alBufferData now behaves as if calling alBufferStorageSOFT with a flags value of 0.
* More cleanup for buffer loadingChris Robinson2018-01-211-4/+0
| | | | | Don't bother with unnecessary and unused converters, and remove some unsupported queries.
* Handle double-precision buffers in the mixerChris Robinson2018-01-211-0/+5
|
* Remove the old buffer_samples functionsChris Robinson2018-01-211-45/+0
| | | | | | | The symbols are still there and exported to retain ABI compatibility, but they no longer do anything except set an AL_INVALID_OPERATION error. They're also removed from the function and enum tables, since they're not part of any supported extension.
* Expose a preliminary AL_SOFT_map_buffer extension for testingChris Robinson2018-01-201-8/+33

* Store 8-bit sample types directly as unsigned byteChris Robinson2018-01-191-4/+4

* Remove unnecessary private AL_SOFT_buffer_samples2 definitionsChris Robinson2018-01-191-9/+0
|
* Store mulaw and alaw samples directly in the bufferChris Robinson2018-01-171-9/+18
| | | | | | | They're now decompressed on the fly in the mixer. This is not a significant performance issue given that it only needs a 512-byte lookup table, and the buffer stores half as much data (it may actually be faster, requiring less overall memory).
