Build with -Wfloat-conversion + fix all warnings 2024-06-03 21:33:29 +00:00
Ryan C. Gordon e23257307e Introduce formal policy for APIs that return strings. 
This declares that any `const char *` returned from SDL is owned by SDL, and
promises to be valid _at least_ until the next time the event queue runs, or
SDL_Quit() is called, even if the thing that owns the string gets destroyed
or changed before then.

This is noted in the headers as "the SDL_GetStringRule", so this will both be
greppable to find a detailed explaination in docs/README-strings.md and
wikiheaders will automatically turn it into a link we can point at the
appropriate documentation.

Fixes #9902.

(and several FIXMEs, both known and yet-undocumented.)

Ryan C. Gordon 0ec716819e thread: Reworked SDL_CreateThread to be consistent across platforms. 
Also documented missing and weird bits, rename typedefs to fit SDL standards.

Sam Lantinga 02ff85f2f3 Renamed SDL_SIMDGetAlignment() to SDL_GetSIMDAlignment() 2024-05-16 10:22:15 -07:00
Wim Taymans 55d4b44441 camera: move PipeWire camera first in list 
If it fails, we fall back to the next one, which is v4l2.

Wim Taymans a340748c06 camera: add PipeWire camera support 
The PipeWire camera will enumerate the pipewire Video/Source nodes with
their formats.

When capturing is started, a stream to the node will be created and
frames will be captured.

Sam Lantinga d4dc613559 Allow specifying only some SDL_CameraSpec fields when opening a camera 
This allows setting the size without format, or FPS without size, etc.

Sam Lantinga 861815e51d Fixed camera FPS matching 2024-05-02 12:12:20 -07:00
Sam Lantinga 33eaddc565 Cleaned up various type conversion issues 
This makes sure SDL_PixelFormatEnum flows through the internal code correctly, as well as fixing a number of other minor issues.

Ryan C. Gordon 6c080717f2 camera: Reset permissions to undecided when closing camera. 
Otherwise, the permission-granted event will not fire when reopened.
 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 70b89ab70d camera: Added SDL_GetCameraDevicePosition. 
Otherwise, as a property, you have to open each camera device to figure out
which ones are which.

Ryan C. Gordon bdcddf4810 camera: Disconnected cameras become zombies that feed blank frames. 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 99d1337de2 camera: Reenabled macOS/iOS support, with rewritten CoreMedia implementation. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon f8fa08d2b1 camera: Fix compiler warnings on some platforms. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 22dbc0f32f camera: Patched to compile after rebasing to latest in main. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 7191a97fe3 camera: Windows support, through the Media Foundation API! 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.
 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 0b5875825e camera: framerate support. 2024-02-20 15:56:26 -05:00
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 f87d536229 camera: Added more accurate timestamps. 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).
 2024-02-20 15:56:26 -05:00
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 f49ce4a15d camera: Renamed "video_capture" files to "camera" and moved to own subdir. 2024-02-20 15:56:26 -05:00
