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.

camera: turn OFF `DEBUG_CAMERA` debug logging. 2024-02-20 16:09:02 -05:00
Ryan C. Gordon 6296677bc9 camera: Fixed Android hotplug. 2024-02-20 15:56:26 -05:00
Ryan C. Gordon 6c080717f2 camera: Reset permissions to undecided when closing camera. 
Otherwise, the permission-granted event will not fire when reopened.

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 2613e3da24 camera: Rewrote Android support. 
This does something a little weird, in that it doesn't care what
`__ANDROID_API__` is set to, but will attempt to dlopen the system
libraries, like we do for many other platform-specific pieces of SDL.

This allows us to a) not bump the minimum required Android version, which is
extremely ancient but otherwise still working, doing the right thing on old
and new hardware in the field, and b) not require the app to link against
more libraries than it previously did before the feature was available.

The downside is that it's a little messy, but it's okay for now, I think.

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 8db2a3b27a camera: Add an optional property that reports if a camera is back or front. 
This is useful for iOS and Android, so an app can find the camera it cares
about in the list of devices.

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 3dca8a03da camera: Removed some debug logging. 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 2cdff93578 v4l2: Corrected SDL_UDEV_AddCallback return check after #8694. 2024-02-20 15:56:26 -05:00

Ryan C. Gordon 9ae39d52de camera: Add sources to Xcode and Visual Studio projects. 
This still needs updates to actually compile on macOS/iOS, though!
 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).

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 2ad44bd162 camera: Made a pass over all the sources, cleaning up for SDL3 style, etc. 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
