UsbCameraInput()

std::shared_ptr< simaai::neat::Node > simaai::neat::nodes::UsbCameraInput (simaai::neat::UsbCameraInputOptions opt)

Live USB (UVC) MJPEG camera source.

Opens the camera whose stable ID is opt.camera_name (see usb_camera_ids()), requires the exact MJPEG mode opt.width x opt.height at opt.framerate_num/opt.framerate_den, and captures through V4L2.

The node outputs the camera's JPEG frames for VideoSender passthrough (MJPEG) and SimaDecode (MJPEG) on the same Graph. The camera captures into CMA DMA-BUFs that the hardware decoder reads in place, so no frame is copied between capture and decode.

Building a Graph again after the camera was unplugged, moved or renumbered throws; call UsbCameraInput again to open it.

Exceptions

std::invalid_argument	for a missing camera ID or buffer name, or a zero size or rate.
std::runtime_error	when the camera is not connected, is in use, lacks the mode, or sends no decodable frame. The message names the camera ID and lists the connected IDs or the camera's MJPEG modes.

Definition at line 94 of file UsbCameraInput.h.

UsbCameraInput()

std::shared_ptr< simaai::neat::Node > simaai::neat::nodes::UsbCameraInput (simaai::neat::UsbCameraInputOptions opt, const simaai::neat::UsbCameraInfo & info)

UsbCameraInput for a camera that usb_camera_info(opt) already checked.

Reuses info instead of opening the camera again: it validates opt like the overload above and confirms, from sysfs only, that info.device still belongs to the camera ID opt.camera_name. Pass the same opt that produced info; the mode is not checked again.

Exceptions

std::invalid_argument	for invalid options, as the overload above.
std::runtime_error	when info is stale (the camera was unplugged, moved or renumbered since) or describes another camera; call usb_camera_info again.

Definition at line 107 of file UsbCameraInput.h.
