Thereby allows me substantially to reduce audio latency.

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.

Thomas Harte
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.

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.

Actually, QIODevice is listed as reentrant. So no need to forward audio.
...
That said, latency is still absurd for some reason.

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

QIODevice isn't guaranteed thread safe, so use of it is now thread confined.

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.
