capture_camera()

BufferOperation MayaFlux::Kriya::BufferOperation::capture_camera ( const std::shared_ptr< IO::IOManager > &  io_manager, const IO::CameraConfig &  config, BufferCapture::CaptureMode  mode = BufferCapture::CaptureMode::TRANSIENT, uint32_t  cycle_count = 1, std::optional< Portal::Graphics::RenderConfig >  render = std::nullopt  )

static

Open and capture a camera through IOManager.

Parameters

render

Draws the live camera when given; a camera buffer that already renders is left as it is. Without it the capture only routes the frames.
