Property Descriptions
Current
The current camera driver, or nil if no driver has been initialized..
class property Current: TSdlCameraDriver read GetCurrent
Type: TSdlCameraDriver
Remarks
It is safe to use this property from any thread
DriverCount
The number of built-in camera drivers.
This property 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.
By default, SDL tries all drivers, in its preferred order, until one is found to be usable.
class property DriverCount: Integer read GetDriverCount
Type: Integer

Remarks
It is safe to use this property from any thread
Drivers
The built in camera drivers.
The list of camera drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list.
class property Drivers[const AIndex: Integer]: TSdlCameraDriver read GetDriver
Type: TSdlCameraDriver

Remarks
It is safe to use this property from any thread
Name
The name of a built in camera driver.
The list of camera drivers is given in the order that they are normally initialized by default; the drivers that seem more reasonable to choose first (as far as the SDL developers believe) are earlier in the list.
The names of drivers are all simple, low-ASCII identifiers, like "v4l2", "coremedia" or "android". These never have Unicode characters, and are not meant to be proper names.
