--     This function returns a hardcoded number. This never returns a negative value; if there are no drivers compiled into this build of SDL, this function returns zero. The presence of a driver in this list does not mean it will function, it just means SDL is capable of interacting with that interface. For example, a build of SDL might have v4l2 support, but if there\'s no kernel support available, SDL\'s v4l2 driver would fail if used.

--
--     This returns a list of all formats and frame sizes that a specific camera can offer. This is useful if your app can accept a variety of image formats and sizes and so want to find the optimal spec that doesn\'t require conversion.
--
--     This function isn\'t strictly required; if you call SDL_OpenCamera with a NULL spec, SDL will choose a native format for you, and if you instead specify a desired format, it will transparently convert to the requested format on your behalf.
--

--
--     Note that it\'s legal for a camera to supply an empty list. This is what will happen on Emscripten builds, since that platform won\'t tell /anything/ about available cameras until you\'ve opened one, and won\'t even tell if there /is/ a camera until the user has given you permission to check through a scary warning popup.

-- | Open a video recording device (a \"camera\").

--
--     If you would rather accept whatever format the device offers, you can pass a NULL spec here and it will choose one for you (and you can use SDL_Surface\'s conversion\/scaling functions directly if necessary).
--
--     You can call @SDL_GetCameraFormat()@ to get the actual data format if passing a NULL spec here. You can see the exact specs a device can support without conversion with @SDL_GetCameraSupportedFormats()@.
--
--     SDL will not attempt to emulate framerate; it will try to set the hardware to the rate closest to the requested speed, but it won\'t attempt to limit or duplicate frames artificially; call @SDL_GetCameraFormat()@ to see the actual framerate of the opened the device, and check your timestamps if this is crucial to your app!
--
--     Note that the camera is not usable until the user approves its use! On some platforms, the operating system will prompt the user to permit access to the camera, and they can choose Yes or No at that point. Until they do, the camera will not be usable. The app should either wait for an SDL_EVENT_CAMERA_DEVICE_APPROVED (or SDL_EVENT_CAMERA_DEVICE_DENIED) event, or poll @SDL_GetCameraPermissionState()@ occasionally until it returns non-zero. On platforms that don\'t require explicit user approval (and perhaps in places where the user previously permitted access), the approval event might come immediately, but it might come seconds, minutes, or hours later!

-- | Query if camera access has been approved by the user.
--
--     Cameras will not function between when the device is opened by the app and when the user permits access to the hardware. On some platforms, this presents as a popup dialog where the user has to explicitly approve access; on others the approval might be implicit and not alert the user at all.
--
--     This function can be used to check the status of that approval. It will return SDL_CAMERA_PERMISSION_STATE_PENDING if waiting for user response, SDL_CAMERA_PERMISSION_STATE_APPROVED if the camera is approved for use, and SDL_CAMERA_PERMISSION_STATE_DENIED if the user denied access.
--
--     Instead of polling with this function, you can wait for a SDL_EVENT_CAMERA_DEVICE_APPROVED (or SDL_EVENT_CAMERA_DEVICE_DENIED) event in the standard SDL event loop, which is guaranteed to be sent once when permission to use the camera is decided.

{-# NOINLINE sDL_ReleaseCameraFrame #-}

-- | Release a frame of video acquired from a camera.
--
--     Let the back-end re-use the internal buffer for camera.
--
--     This function /must/ be called only on surface objects returned by @SDL_AcquireCameraFrame()@. This function should be called as quickly as possible after acquisition, as SDL keeps a small FIFO queue of surfaces for video frames; if surfaces aren\'t released in a timely manner, SDL may drop upcoming video frames from the camera.
--
--     If the app needs to keep the surface for a significant time, they should make a copy of it and release the original.
--
--     The app should not use the surface again after calling this function; assume the surface is freed and the pointer is invalid.
--
--     [@camera@]: opened camera device.
--
--     [@frame@]: the video frame surface to release.
--
--     [Thread safety]: It is safe to call this function from any thread.
