c40d858f02 Switches back to angular stuff at input resolution; ensures all S-Video modes work.
Now to roll back onto composite. Fingers crossed!

8b6879a782 Brief detour: introduces myself to C++11 multiline string literals.
A full cleaning coming soon, I imagine.

246b474a25 Removes ONE_BIG_LOCK, having effectively neutered it anyway.
Starts work on more explicit API usage validation. Maybe the issue isn't a race condition?

745797b596 Introduces a stencil buffer plus the inter-frame clearing it allows. 2020-08-16 16:42:32 -04:00

940e9e037e Adds first_scan to LineMetadata.
Also reorders `Line` fields to match `Scan` fields, just for visual consistency.
2020-08-16 08:59:37 -04:00

230b9fc9e6 Permits multiple simultaneous scan reading ranges.
Also updates the OpenGL scan target as per the latest movements of things.

637ec35d6a Adds getters for standard colour-space conversion matrices.
These are just more details on the meaning of the colour spaces, so I think they belong here.

8fa89baf54 Slightly cleans up Xcode project; reenables kiosk-for-Mac builds. 2020-08-10 21:43:32 -04:00
Thomas Harte
8374a5e579 Adds superficially correct compositeSampleLuminance8Phase8 function.
Thereby uncovering a minor error in my decoding of colour phase.

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.

eadda6a967 Further strips OpenGL from the macOS target. 2020-08-09 22:17:27 -04:00

c1dc42a094 Add comment on latent design aim.
In the hope that I don't forget why I did this.

6384ff3ee7 Add fix for data_type_size_ for owners that don't change texture pointer upon new modals. 2020-08-09 21:17:51 -04:00
Thomas Harte
ced4a75a1a Adds note on the buffering scan target's minor adaptation of data_offset. 2020-08-09 20:44:46 -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
Thomas Harte
583f6b1ba2 Modifies BufferingScanTarget to allow has-a relationship.
I might switch fully to has-a. Further consideration required.

4c9418f59a Guarantees alignof(4) on all GPU-bound structures.
Taken as given: Metal's requirement here is reasonable enough that it'll either be the same as other frameworks, or at least possibly help them down a fast path.

7b1708f0bc Gets explicit that the delegate_ doesn't need a memory barrier. 2020-07-31 18:21:47 -04:00

23f381f381 Fixes frame_is_complete_, gets rid of active_line_, explains ONE_BIG_LOCK in set_write_area. 2020-07-29 23:03:38 -04:00
Thomas Harte
51ad423eca Resolves off-by-one error in line writing, adds diagnostic one-big-lock option. 2020-07-29 22:45:13 -04:00
Thomas Harte
72a8fef989 Switches to much more straightforward Line/LineMetadata storage.
Spoiler: covering this whole segment behind producer_mutex_ seems to resolve all output issues, so clearly the existing logic isn't functioning correctly. Making it simpler seems like a pretty obvious way to get to the bottom of that.
2020-07-29 21:49:17 -04:00

02f41ee513 This has become the general producer mutex, might as well name it as such. 2020-07-29 21:34:07 -04:00
Thomas Harte
5165e65021 Reduces scan_buffer_ to a saner size.
Albeit still probably overspecified.
2020-07-28 22:36:57 -04:00

74788ccf8e Pulls the BufferingScanTarget into a separate file. 2020-07-22 22:16:47 -04:00
Thomas Harte
0da5c07942 Starts splitting ring-buffer stuff from OpenGL stuff.
Initially via two very codependent classes.
