CameraOutput
interface CameraOutput extends HybridObjectA CameraOutput is the base-class of all
outputs that can be connected to the CameraSession.
Discussion
You can extend the CameraOutput Nitro spec
in native and conform to the NativeCameraOutput
interface/protocol to create custom outputs which can
be connected to the CameraSession.
This is useful for building custom capture pipelines,
such as private HDR implementations, or fully custom
video pipelines (e.g. for batching/segmenting video).

Properties
currentResolution?
readonly optional currentResolution?: SizeThe resolution that the underlying capture pipeline has resolved
this CameraOutput to, in sensor-native (un-rotated) pixels,
or undefined if the output has not yet been connected to a
CameraSession.
Discussion
The selected Size may differ from the requested
Size (e.g. from PhotoOutputOptions.targetResolution),
as the CameraSession negotiates resolutions across
attached CameraOutputs, connected CameraDevice
capabilities, and enabled Constraints.
Discussion
For outputs that are not pixel-based (e.g. metadata-only outputs),
this reports the resolution of the upstream video stream feeding
the output, or undefined if no video input is attached.
mediaType
readonly mediaType: MediaTypeThe media type of the content being streamed
by this CameraOutput.
outputOrientation
outputOrientation: CameraOrientationGets or sets the output orientation of this CameraOutput.
Individual implementations of CameraOutput
may choose different strategies for implementing
output orientation, for example:
- A Photo output might apply orientation via EXIF flags.
- A Video output might apply orientation via track transform metadata.
- A Preview output might apply orientation via view transforms.
- A Frame output might not apply orientation and only pass it as a
property via the
Frameobject, unless explicitly configured to physically rotate buffers.
