3597f687de Continues sidling towards composite & S-Video handling. 2020-08-19 21:20:06 -04:00
Thomas Harte
8811506adf Starts towards building a compound[/composition?] buffer. 
I now need to discover whether I can use natural integer texture coordinates.

Thomas Harte
940e9e037e Adds first_scan to LineMetadata.

Thomas Harte
645c29f853 Adds an intermediate buffer to correct inter-frame smoothing.

7ac88536dd Respects machine aspect ratio. 
To an extent. Doesn't currently deal with cropping of machines when the window aspect ratio is smaller.
 2020-08-14 21:24:25 -04:00

230b9fc9e6 Permits multiple simultaneous scan reading ranges.

27ca782cac Enables blending; attempts to enable frame preservation. 
The latter seems to be evidencing a double buffer at play. More investigation required.

On the plus side, the direct route is still well within GPU budget at 4k on my Core M. So a huge improvement there.

Thomas Harte
8374a5e579 Adds superficially correct compositeSampleLuminance8Phase8 function. 
Thereby uncovering a minor error in my decoding of colour phase.
 2020-08-10 21:33:59 -04:00
Thomas Harte
525233e10b Ensures all input data types are parseable in Metal. 
Though now I need to think a bit more about the best way to compose signal-type conversions, and whether output-type calculations (i.e. gamma, brightness) are applied.

Assuming an 'RGB' output.

57fecdc09e Ties everything together in an attempt to display RGB scans. 
I'm actually just getting a mess of pixels, but it's something!
 2020-08-09 18:41:15 -04:00

f16ad8f71d Takes a shot at submitting texture changes. 2020-08-09 17:59:52 -04:00
Thomas Harte
e340685a99 Seemingly proves that proper geometry is reaching Metal by drawing scans. 
No in-buffer accumulation yet, but this is progress. If I can add accumulation and stencil clearing, I'm not doing badly.
 2020-08-08 23:11:44 -04:00
Thomas Harte
df89a8771c Makes an attempt to have the emulator fill the actual GPU buffers. 
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.
 2020-08-08 22:49:02 -04:00
Thomas Harte
bdcf266e45 Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs. 
Also thereby eliminates the need for a forced alignas(4) on various structs.
 2020-08-08 17:27:32 -04:00

edf41b06fd Eliminates the quad buffer. 
Vertices can be adduced from vertex ID.
 2020-08-08 17:12:49 -04:00
Thomas Harte
38960a08d6 Adds adjustment for display aspect ratio. 
While also realising that I appear to be getting away without an MTLVertexDescriptor for Scans. Maybe OpenGL has prejudiced me, and they're actually optional for interleaved data?
 2020-08-07 22:29:24 -04:00
Thomas Harte
fbda7aab23 Does just enough to get the correct (aspect ratio aside) output of scan outlines. 
So, up next, can I start streaming these things?

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.

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.
 2020-06-10 22:14:54 -04:00
Thomas Harte
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.

63ad1290f4 Actually, QIODevice is listed as reentrant. So no need to forward audio. 
That said, latency is still absurd for some reason.

7c7cb61d2f Corrects missing audio, at the cost of frame rate.
