Sam Lantinga 4ba6aeee9d A second take on HDR support with an SDR white point and HDR headroom 
This better reflects how HDR content is actually used, e.g. most content is in the SDR range, with specular highlights and bright details beyond the SDR range, in the HDR headroom.

This more closely matches how HDR is handled on Apple platforms, as EDR.

This also greatly simplifies application code which no longer has to think about color scaling. SDR content is rendered at the appropriate brightness automatically, and HDR content is scaled to the correct range for the display HDR headroom.

Anonymous Maarten cbf0b1ce81 testcamera: create window and renderer through test library 2024-02-21 00:49:15 +01:00
Ryan C. Gordon f59c66a97f testcamera: Allow app to flip between a front and back camera. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon b1ed49772c camera: Replace testcamera.c with testcameraminimal.c 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 47313bba32 camera: SDL_GetCameraDevices should not report "no devices" like an error. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 0b8617f71d test: Fixed CMake to build testcameraminimal correctly on WinRT. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 67708f9110 camera: Emscripten support! 
This also adds code to deal with waiting for the user to approve camera
access, reworks testcameraminimal to use main callbacks, etc.

Ryan C. Gordon 87e7046fca camera: Public API functions should say "Format" not "Spec" to match audio. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon d3e6ef3cc6 camera: Massive code reworking. 
- Simplified public API, simplified backend interface.
- Camera device hotplug events.
- Thread code is split up so it backends that provide own threads can use it.
- Added "dummy" backend.

Note that CoreMedia (Apple) and Android backends need to be updated, as does
the testcamera app (testcameraminimal works).

Ryan C. Gordon cb10c80aaf camera: Reworked to operate with a driver interface, like other subsystems. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 7ae955ce68 camera: Renamed everything from "video capture" to "camera", wired to CMake. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon f49ce4a15d camera: Renamed "video_capture" files to "camera" and moved to own subdir. 2024-02-20 15:56:26 -05:00

Sam Lantinga d451fcd7a7 Fixed HDR video content being too bright on Apple platforms 
This probably isn't the exact formula that we need, but it's much closer to correct.

Sam Lantinga c09daf8388 Removed unused variables 2024-02-15 14:11:04 -08:00
Sam Lantinga 2f7c24e4be Removed SDL_HINT_RENDER_SCALE_QUALITY 
Textures now default to linear filtering, use SDL_SetTextureScaleMode(texture, SDL_SCALEMODE_NEAREST) if you want nearest pixel mode instead.
 2024-02-12 09:54:33 -08:00
Sam Lantinga 7cb1ca60ec Removed SDL_HINT_RENDER_OPENGL_SHADERS

Sam Lantinga a538936821 Renamed SDL_HINT_LINUX_JOYSTICK_DEADZONES to SDL_HINT_JOYSTICK_LINUX_DEADZONES 2024-02-12 09:54:33 -08:00
Sam Lantinga 9ce7fe2848 Removed SDL_HINT_ACCELEROMETER_AS_JOYSTICK 
Sensors are a first-class object in SDL and we haven't gotten any feedback that this feature is useful these days.

Closes https://github.com/libsdl-org/SDL/pull/7879

Sam Lantinga cacac6cc34 Updated structure and field names for consistency 
Type names are camel case and field names are snake case except for fields ending in id, which are capitalized.

Sam Lantinga 3158342441 Use SDL_Color for SDL_RenderGeometryRaw() and add SDL_RenderGeometryRawFloat() 
Eventually we can re-add a fast path for that data down to the individual renderers. Setting color scale would still require converting to float, and most hardware accelerated renderers prefer to consume colors as float, so this requires some thought and performance testing.

Sam Lantinga f9c57e16b0 Don't test 10-bit pixel format conversion 
We either need to explicitly test using the sRGB colorspace or update the tests for HDR10 color conversion. We'll just disable them for now, as these formats aren't commonly used in games.
