}

A profiling event corresponding to a single camera frame. This message collects important details and timestamps involved in producing a single camera frame. Next ID: 17

Fields

session_id: Option<u64>

Identifier for the CameraCaptureSession this frame originates from. See: https://developer.android.com/reference/android/hardware/camera2/CameraCaptureSession

camera_id: Option<u32>

Identifier for the camera sensor that is the source of this frame. This may be either a physical or logical camera (up to vendor interpretation).

frame_number: Option<i64>

The frame number identifying this frame on this camera.

request_id: Option<i64>

Identifier for the CaptureRequest. See: https://developer.android.com/reference/android/hardware/camera2/CaptureRequest

If multiple cameras are streaming simultaneously, the request_id may be used to identify which frames were captured in service of the same request.

request_received_ns: Option<i64>

The CLOCK_BOOTTIME timestamp at which the camera framework request is received by the camera HAL pipeline. Note that this request may wait for some time before processing actually begins. See also request_processing_started_ns.

request_processing_started_ns: Option<i64>

The CLOCK_BOOTTIME timestamp at which the framework request is accepted for processing by the camera HAL pipeline. This is the time at which the pipeline actually begins to work on the request.

start_of_exposure_ns: Option<i64>

The CLOCK_BOOTTIME timestamp at which the sensor begins its exposure.

start_of_frame_ns: Option<i64>

The CLOCK_BOOTTIME timestamp corresponding to the sensor start of frame event.

responses_all_sent_ns: Option<i64>

The CLOCK_BOOTTIME timestamp at which the camera HAL has sent all responses for the frame.

capture_result_status: Option<i32>

skipped_sensor_frames: Option<i32>

The number of sensor frames that were skipped between this frame and the previous frame. Under normal operation, this should be zero. Any number greater than zero indicates dropped sensor frames.

capture_intent: Option<i32>

The value of CONTROL_CAPTURE_INTENT. See: https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#CONTROL_CAPTURE_INTENT

num_streams: Option<i32>

The number of streams in the capture request.

node_processing_details: Vec<CameraNodeProcessingDetails>

vendor_data_version: Option<i32>

These fields capture vendor-specific additions to this proto message. In practice vendor_data typically contains a serialized message of the vendor’s design, and vendor_data_version is incremented each time there is a backwards incompatible change made to the message.

vendor_data: Option<Bytes>
