pub fn find_by_id(id: &str) -> Option<CameraDevice>Expand description
Locate the CameraDevice whose stable id matches id by
re-probing the OS via list_cameras. Used by
super::gstreamer_video::GstreamerVideoCapture::from_camera to
resolve the picker’s camera id back to its OS-native source
element on every recording start (M-CAM.4). Returns None when
the camera has been unplugged since enumeration.
