CameraComponent

CameraComponent abstracts ColorCamera and MonoCamera nodes and supports mocking the camera when recording is passed during OakCamera initialization. When using :ref:`Replaying` feature, this component will mock the camera by sending frames from the host to the OAK device (via XLinkIn node).

Usage

from depthai_sdk import OakCamera

with OakCamera() as oak:
    # Create color camera
    color = oak.create_camera('color')

    # Visualize color camera frame stream
    oak.visualize(color.out.main, fps=True)
    # Start the pipeline, continuously poll
    oak.start(blocking=True)

Component outputs

• :attr:`main <depthai_sdk.components.CameraComponent.Out.main>` - Uses one of the outputs below.
• :attr:`camera <depthai_sdk.components.CameraComponent.Out.camera>` - Default output. Streams either ColorCamera's video (NV12) or MonoCamera's out (GRAY8) frames. Produces :ref:`FramePacket`.
• :attr:`replay <depthai_sdk.components.CameraComponent.Out.replay>` - If we are using :ref:`Replaying` feature. It doesn't actually stream these frames back to the host, but rather sends read frames to syncing mechanism directly (to reduce bandwidth by avoiding loopback). Produces :ref:`FramePacket`.
• :attr:`encoded <depthai_sdk.components.CameraComponent.Out.encoded>` - If we are encoding frames, this will send encoded bitstream to the host. When visualized, it will decode frames (using cv2.imdecode for MJPEG, or pyav for H.26x). Produces :ref:`FramePacket`.
