* Don't update the channel format if all JACK ports were allocatedChris Robinson2014-12-231-9/+11
|
* Try the device-specified channel configuration firstChris Robinson2014-12-231-3/+15
| | | | | This does basically no checking that the channel config is correct, but should be good enough for when non-stereo modes are requested.
* Use the custom ringbuffer instead of JACK'sChris Robinson2014-12-231-41/+20
|
* Add a lockless ringbufferChris Robinson2014-12-232-0/+290
| | | | | | Largely copied from JACK, it's extended to work with user-specified element sizes instead of bytes. This is necessary to be able to work with 6- and 7- channel output modes.
* Don't set unused pointers to NULL, don't try to write 0 samplesChris Robinson2014-12-231-7/+8
|
* At least measure the ringbuffer size for JACK's latencyChris Robinson2014-12-231-1/+17
| | | | | | We should also add the port latency, but there's currently no way to ensure it's synchronized with the ringbuffer (the ringbuffer will update before the port latency gets updated).

| | | | | | | | | | | | | | | | | | | | | | | | A few notes about it: The OpenAL device's requested buffer metrics are ignored, and instead the device will keep one JACK-sized buffer's worth of audio prepared for JACK's next process request. Output is restricted to 32-bit float stereo. Part of this is because JACK requires a buffer size that's a power of 2 (measured in samples), and the ringbuffer requires a buffer size that's a power of 2 (measured in bytes). A channel count of 6 (5.1) or 7 (6.1) will not work without causing a sample to split over the edge of the ringbuffer. Additioanlly, JACK doesn't provide information about what channel configuration a device or set of ports has, so there's no way to know what ports 3 and up map to (even the first two ports are unknown, but assuming stereo seems to work well enough). There is no device latency measurement (for AL_SOFT_source_latency) due to the non-atomicity between the ringbuffer's read size and port latency. A method is needed to ensure the ringbuffer's read size and port latency can both be measured between the end of a JACK update cycle (when the port latency has been updated with the newly-retrieved audio) and the following ringbuffer read update.
