d08ffd6c8b Makes sure the timer really, really is on a different thread. 
Thereby allows me substantially to reduce audio latency.

Thomas Harte
79833deeaf With some attempt at vsync prediction, seeks to smooth audio/video output. 
There's plenty more work to do here, but hopefully it takes the issue immediately off the table.

405e9e7c68 Shunts audio into its own QThread. 
For the record, this was the first means I found of attempting that which actually seemed to work. A plain QThread, with something `connect`ed to its `started` signal didn't seem to work (perhaps `connect` is smart at thread confinement?), `moveToThread` didn't work on the audio output after the fact, etc.

5f13ee7c19 Simplifies AudioBuffer by consolidating logic into writes. 
This is kind of fiddling in the margins though; I'm having a lot of difficulty determining the semantically-correct way to get Qt not to funnel all activity through a single thread.
 2020-06-09 23:56:08 -04:00
Thomas Harte
d9f02aecdf Adds an additional buffer. To reduce latency. No, really. 
Specifically: there's no way to guarantee no overbuffering due to the startup race, other than having QAudioOutput obtain data by pull rather than push. But if it's pulling then that implies an extra buffer. And since the sizes it may pull are not explicit, there's guesswork involved there.

So: no extra buffer => uncontrollable risk of over-buffering. Extra buffer => a controllable risk of over-buffering.

bcb23d9a15 Attempt to reduce audio latency. Unsuccessfully. 2020-06-08 21:30:35 -04:00
Thomas Harte
d027450502 Consolidates timer/thread ownership for the timer. 2020-06-07 00:31:46 -04:00
Thomas Harte
63ad1290f4 Actually, QIODevice is listed as reentrant. So no need to forward audio. 
That said, latency is still absurd for some reason.
 2020-06-06 23:47:57 -04:00
Thomas Harte
7c7cb61d2f Corrects missing audio, at the cost of frame rate. 
I'm now spinning on the ability of QAudioOutput to accept additional data.
 2020-06-06 22:35:50 -04:00
Thomas Harte
68b165e244 QIODevice isn't guaranteed thread safe, so use of it is now thread confined. 2020-06-06 21:14:04 -04:00
Thomas Harte
fe1b6812f1 Fixes processing cap and attempts full-rate video output. 
Audio now seems to be present, though hugely stuttered.
 2020-06-06 19:47:35 -04:00
Thomas Harte
378ff39e5e Makes an unsuccessful attempt at producing audio. 
On the plus side, it does seem successfully to sniff out an appropriate audio format and to communicate mono/stereo onward.

ead32fb6b2 Return to old behaviour if --logical-keyboard isn't specified.

b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
