Accesing Stream State

[LBoullosa]

Hi!,

Is there a way to get the stream state to know exactly is the camera is streaming, is closed or whatever state could exists?

I see this kind of messages in the log,

[CameraStateMachine] New public camera state CameraState{type=CLOSING, error=null} from CLOSING and null
[CameraStateMachine] Publishing new public camera state CameraState{type=CLOSING, error=null}
[Camera2CameraImpl] {Camera@558aa2d[id=0]} Resetting Capture Session
[Camera2CameraImpl] {Camera@558aa2d[id=0]} Releasing session in state CLOSING
[StreamStateObserver] Update Preview stream state to IDLE

Camera2CameraImpl] {Camera@558aa2d[id=0]} Transitioning camera internal state: CLOSING --> INITIALIZED
[CameraStateRegistry] Recalculating open cameras:
[CameraStateRegistry] Camera State
[CameraStateRegistry] -------------------------------------------------------------------
[CameraStateRegistry] Camera@558aa2d[id=0] CLOSED
[CameraStateRegistry] Camera@8f4cbae[id=1] UNKNOWN
[CameraStateRegistry] -------------------------------------------------------------------
[CameraStateRegistry] Open count: 0 (Max allowed: 1)
[CameraStateMachine] New public camera state CameraState{type=CLOSED, error=null} from CLOSED and null
[CameraStateMachine] Publishing new public camera state CameraState{type=CLOSED, error=null}

Thanks in advance,

I found a way, not too pretty but works. This needs to be done under platform code for android

while (platformView.PreviewStreamState.Value != PreviewView.StreamState.Streaming)
     await Task.Delay(200);

As a possible new feature could be published with have some events or something. This will be in the direction to avoid initialization failures due to concurrency/synchronicity natural issues when we want to integrate this great library with our apps.
