* Camera device active session interface.
* Obtained via ICameraDevice::open(), this interface contains the methods to
* configure and request captures from an active camera device.
interface ICameraDeviceSession extends @3.3::ICameraDeviceSession {
* configureStreams_3_4:
* Identical to @3.3::ICameraDeviceSession.configureStreams, except that:
* - The requested configuration includes session parameters.
* @return Status Status code for the operation, one of:
* OK:
* On successful stream configuration.
* If there has been a fatal error and the device is no longer
* operational. Only close() can be called successfully by the
* framework after this error is returned.
* If the requested stream configuration is invalid. Some examples
* of invalid stream configurations include:
* - Including more than 1 INPUT stream
* - Not including any OUTPUT streams
* - Including streams with unsupported formats, or an unsupported
* size for that format.
* - Including too many output streams of a certain format.
* - Unsupported rotation configuration
* - Stream sizes/formats don't satisfy the
* camera3_stream_configuration_t->operation_mode requirements
* for non-NORMAL mode, or the requested operation_mode is not
* supported by the HAL.
* - Unsupported usage flag
* The camera service cannot filter out all possible illegal stream
* configurations, since some devices may support more simultaneous
* streams or larger stream resolutions than the minimum required
* for a given camera device hardware level. The HAL must return an
* ILLEGAL_ARGUMENT for any unsupported stream set, and then be
* ready to accept a future valid stream configuration in a later
* configureStreams call.
* @return halConfiguration The stream parameters desired by the HAL for
* each stream, including maximum buffers, the usage flags, and the
* override format.
